Three-WayControl Valve
Three-WayControl Valve
Inlet Outlet
With the cover chamber vented to atmosphere, thevalve will open from line pressure under the disc.
A simple control which either opens the valve wide orcloses it tightly is a three-way valve. The type of opera-tion this control gives is called “non-modulating” becausethe valve cannot pause in a partially open position.
Once the control is turned to either position, operatingfluid flows into or out of the cover chamber until the valveis open or closed. For example...
To open...Control is turned to exhaustcover chamber pressure.
To close...Control is turned toapply pressure tocover chamber.
If inlet pressure is connected into the cover chamber, thevalve closes tightly. In this example, the 400 pound differ-ence is the force which pushes the disc against the seatand causes the valve to seal drip-tight.
Ordinary three-way valves usual-ly are not satisfactory becausethey require so much force tooperate. An easy-turning controlwhich can be operated in a vari-ety of ways is usually used. Hereare some of them and how theyare operated...
By hand
With a solenoid By pressure
By a difference intwo pressures
By a float
When no pressure is in the valve, thespring and the weight of the diaphragmassembly hold the valve closed.

Valve ClosedWhen the modulating control closes sufficiently to direct agreat enough pressure into the cover chamber to over-come opening forces of line pressure, the main valve clos-es.
Valve OpenWhen the throttling control opens to a point where morepressure is relieved from the cover chamber than therestriction can supply, cover pressure is reduced and thevalve opens.
Valve ThrottlingThe main valve modulates to any degree of opening in responseto changes in the throttling control. At an equilibrium point themain valve opening and closing forces hold the valve in balance.This balance holds the valve partially open, but immediatelyresponds and readjusts its position to compensate for anychange in the controlled condition.
So far only valves that either open wide or close tightly (non-modulating) have been illustrated. TheCLA-VAL Automatic Valve modulates if the cover pressure is held between the inlet and outlet pressure.To do this requires a slightly different kind of control system.

Q What is the spring for ina Hytrol valve?
A To provide enough forceto close the valve whenno difference existsbetween inlet, coverand outlet pressures.When the inlet pressureis greater than outletpressure (even by asmall amount) thehydraulic forces, NOTTHE SPRING hold thevalve tightly closed.
Q Can pressure other than line pressure be used to operate CLA-VAL Valves?
A Yes. Frequently, when line fluid is too dirty or otherwise unsuitable, a separatesource of pressure is desired. Clean water, air (with some limitations), or oilare suitable. The important point is to make sure the operating pressure isequal or greater than inlet pressure AT ALL TIMES.
Q What should be done if line pressure is very low? (Below 10 psi)
A Usually a separate source of operating pressure is required. A spring to openthe valve may be necessary. Consult the factory for recommendations.
Q Can the opening and closing speed of a CLA-VALValve be controlled?
A Yes. It is a matter of controlling the rate at whichoperating fluid flows into or out of the cover chamber.
Here is a typical valve equipped with both openingand closing speed controls. A simple needle valvecan be used for these controls.
Q Which way should fluid flow through a CLA-VAL Valve?
A Just as with any globe valve, the usual way is “under–the–disc” as shown. Themain exception to the “under-the-disc” rule of thumb is the check valve.

Hytrol Valve
Principle of Operation
Full Open OperationWhen pressure in the cover chamberis relieved to a zone of lower pres-sure, the line pressure at the valveinlet opens the valve, allowing fullflow.
Modulating ActionThe valve holds any intermediateposition when operating pressuresare equal above and below thediaphragm. A Cla-Val “Modulating”Pilot Control will allow the valve toautomatically compensate for linepressure changes.
Tight Closing OperationWhen pressure from the valve inletis applied to the cover chamber, thevalve closes drip-tight.
• Drip - Tight, Positive Seating• Service Without Removal From Line• Threaded, Flanged or Grooved Ends• Globe or Angle Pattern• 100% Factory-Tested
The Cla-Val Model 100-01 Hytrol Valve is a hydraulicallyoperated, diaphragm actuated, globe or angle pattern valve.It consists of three major components: body, diaphragmassembly, and cover. The diaphragm assembly is the onlymoving part.
The diaphragm assembly is guided top and bottom by aprecision machined stem. It utilizes a non-wickingdiaphragm of nylon fabric bonded with synthetic rubber. Aresilient synthetic rubber disc retained on three and one halfsides by a disc retainer forms a drip-tight seal with the renewableseat when pressure is applied above the diaphragm.
The Model 100-01 is the basic valve used in nearly allCla-Val Automatic Control Valves. It is the valve of choicefor system applications requiring remote control, pressureregulation, solenoid operation, rate of flow control, liquidlevel control or check valve operation. The rugged simplicityof design and packless construction assure a long life ofdependable, trouble-free operation. It is available in variousmaterials and in a full range of sizes, with either threaded,flanged or grooved ends. Its applications are unlimited.

Viton® Rubber Parts - suffix KBOptional diaphragm, disc and o-ring fabri-cated with Viton® synthetic rubber. Viton® iswell suited for use with mineral acids, saltsolutions, chlorinated hydrocarbons, andpetroleum oils; and is primarily used in hightemperature applications up to 250° F. Donot use with epoxy coatings above 175° F.
Epoxy Coating - suffix KCAn FDA approved fusion bonded epoxycoating for use with cast iron, ductile ironor steel valves. This coating is resistant tovarious water conditions, certain acids,chemicals, solvents and alkalies. Epoxycoatings are applied in accordance withAWWA coating specifications C550-90.Do not use with temperatures above 175° F.
Dura-Kleen® Stem - suffix KDThis stem is designed for applicationswhere water supplies containing dissolvedminerals create deposits that build-up on astandard stem and hamper valve opera-tion. A patented self-cleaning design onthe stem allows all valve sizes to operatefreely in the harshest conditions.
Delrin® Sleeved Stem - suffix KGThe Delrin® sleeved stem is designed forapplications where water supplies containdissolved minerals which can formdeposits that build up on the valve stemand hamper valve operation. Scale build-upwill not adhere to the Delrin® sleeve stem.Delrin® sleeved stems are not recommend-ed for valves in continuous operation wheredifferential pressures are in excess of 80 psi(2" and larger Hytrol valves).
Heavy Spring - suffix KHThe heavy spring option is used in applica-tions where there is low differential pres-sure across the valve, and the additionalspring force is needed to help the valveclose. This option is best suited for valvesused in on-off (non-modulating) service.
Anti-Cavitation Trim- suffix KOAnti-Cavitation Trim components consist ofa stainless steel radial slotted disc guideand seat. This system is used when highdifferentials are present across the valve.
Water Treatment Clearance - suffix KWThis additional clearance is beneficial inapplications where water treatment com-pounds can interfere with the closing of thevalve. The smaller outside diameter discguide provides more clearance betweenthe disc guide and the valve seat. Thisoption is best suited for valves used in on-off (non-modulating) service.

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positions are acceptable. Due tocomponent size and weight of 8 inch and larger valves, installation with cover UP is advisable. We recommend isolation valves be installed on inlet and outlet for maintenance.Adequate space above and around the valve for service personnel should be considered essential. A regular maintenance program should be established based on the specificapplication data. However, we recommend a thorough inspection be done at least once a year. Consult factory for specific recommendations.

• Virtually Cavitation Free Operation
• Severe Service Design - High Pressure Differentials
• Reduced Noise and Vibration
• 316 Stainless Steel Disc Guide and Seat Standard
• Drip -Tight, Positive Sealing
• Service Without Removal From Line
• Retrofit to Standard Hytrol Valves
The Cla-Val Model 100-01KO Anti-Cavitation Hytrol Valve is designed for appli-cations where there is a high potential for damage from cavitation. Specify thisvalve series for a wide variety of control valve applications having pressure dif-ferentials up to 300 PSID or for relief valves having atmospheric discharge up to150 PSID.
The 100-01KO Hytrol main valve provides optimum internal pressure controlthrough a unique anti-cavitation trim (patent-pending) design. Constructed of 316Stainless Steel, the seat and disc guide trim components feature dual interlockedsleeves containing radial slots that deflect internal flow to impinge upon itself inthe center of the flow path, harmlessly dissipating the potential cavitation dam-age. This unique design also lessens the possibility of fouling if large particles inthe water are present due to the large flow path of the radial slots.
The 100-01KO Hytrol is the basic valve used in Cla-Val Automatic Control Valvesfor high differential applications requiring remote control, pressure regulation,solenoid operation, rate of flow control, or liquid level control.
The Anti-Cavitation Trim components can be retrofitted to existing valves if theapplication indicates an appropriate need. Please consult factory for details.

100-01KO Hytrol Main Valve with Anti-Cavitation Trim Purchase Specifications
FunctionThe valve shall be hydraulically operated, single diaphragm actuated, globe pattern. The valve shall consist of three major compo-nents: the body with seat installed, the cover with bearing installed, and the diaphragm assembly. The diaphragm assembly shall bethe only moving part and shall form a sealed chamber in the upper portion of the valve, separating operating pressure from line pres-sure. Packing glands and/or stuffing boxes are not permitted and there shall be no pistons operating the main valve or pilot controls.Valve body and cover shall be of cast material manufactured in North America. Ductile Iron is standard, other materials shall be avail-able. No fabrication or welding shall be used in the manufacturing process.
DescriptionThe anti-cavitation features of the seat and disc guide detail shall have flow slots equally spaced around their perimeters.The seat slots shall beorientated around the perimeter of the seat so that fluid entering the valve shall flow through the seat slot detail such that the fluid flow convergesin the center chamber of the seat allowing potential cavitation to dissipate. The disc guide slots shall be positioned around the perimeter of thedisc guide, configured and oriented in an angular direction so that fluid flow exiting through the slots is diverted away from direct impact into pres-sure boundary surfaces. Flow exiting the disc guide slots is directed in an angular path to increase the distance between the slot geometry andpressure boundary surfaces. If cavitation conditions exist, the increased distance between the slots and pressure boundary surfaces minimizesthe potential for damage by allowing the cavitation bubbles to dissipate before they come in contact with pressure boundary surfaces. Anti-cavi-tation characteristics shall be controlled by the described slotted seat and disc guide components.The disc guide shall slide in the seat and allowcontrolled flow through the seat slots into the central seat chamber where flow shall continue from the seat chamber and exit through the angu-larly oriented slots of the disc guide.The seat and disc guide features used together shall provide anti-cavitation characteristics suitable for appli-cations where a large controlled pressure drop is desired.The flexible, non-wicking, FDA approved diaphragm shall consist of nylon fabric bonded with synthetic rubber compatible with theoperating fluid. The diaphragm must withstand a Mullins burst test of a minimum of 600 psi per layer of nylon fabric and shall be cycletested 100,000 times to insure longevity. The diaphragm shall be fully supported in the valve body and cover by machined surfaceswhich support no less than one-half of the total surface area of the diaphragm in either the fully open or fully closed position.The valve seat in six inch and smaller size valves shall be threaded into the body. Valve seat in eight inch and larger size valves shallbe retained by flat head machine screws for ease of maintenance. The seat shall be of the solid, one piece design and shall have aminimum of a five degree taper on the seating surface for positive drip tight shut-off. Pressed-in bearings and/or multi-piece seatsshall not be permitted.To insure proper alignment of the valve stem, the valve body and cover shall be machined with a locating lip. No "pinned" covers tothe valve body shall be permitted. All necessary repairs and/or modifications other than replacement of the main valve body shall bepossible without removing the valve from the pipeline.The valve manufacturer shall warrant the valve to be free of defects in material and workmanship for a period of three years from dateof shipment, provided the valve is installed and used in accordance with all applicable instructions. The valve manufacturer shall beable to supply a complete line of equipment from 1 1/4" through 36" sizes and a complete selection of complementary equipment.

Powertrol Valve
The Cla-Val Model 100-02 is a hydraulically operated, diaphragmactuated, globe, or angle pattern valve. It consists of four majorcomponents: body, intermediate chamber, diaphragm assembly,and cover. The diaphragm assembly is the only moving part.
The diaphragm assembly which is guided top and center by a pre-cision machined stem, utilizes a non-wicking diaphragm of nylonfabric bonded with synthetic rubber. The diaphragm forms a sealbetween the cover chamber and intermediate chamber. A syn-thetic rubber disc retained on three and one half sides forms adrip-tight seal with the renewable seat when pressure is appliedabove the diaphragm. As pressure above the diaphragm isrelieved and pressure is applied below the diaphragm, the valveopens wide for full flow. The rate of closing or opening can be con-trolled by modulating flow into or out of the diaphragm chambers.
The Model 100-02 is recommended where independent operatingpressure is desired. Available in various materials and in a fullrange of sizes, with either threaded or flanged ends, its applica-tions are many and varied.
Full Open OperationWhen operating pressure below thediaphragm is applied and operating,pressure is relieved from the coverchamber, the valve is held open,allowing full flow.
Modulating ActionThe valve holds any intermediateposition when operating pressure isequal above and below thediaphragm. A Cla-Val four-way pilotcontrol with "lock" position can main-tain this balance by stop-ping flow in the pilot con-trol system.
Tight Closing OperationWhen pressure below the diaphragmis relieved and operating pressure isapplied to the cover chamber, thevalve closes drip-tight.

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positionsare acceptable. Due to component size and weight of 8 inch and larger valves, installation with cover UP is advisable. We recommend isolationvalves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be consideredessential. A regular maintenance program should be established based on the specific application data. However, we recommend a thoroughinspection be done at least once a year. Consult factory for specific recommendations.
600 SeriesHytrol Valve

TM
• Reduced Cavitation Design• Drip-tight, Positive Seating Action• Service Without Removal From Line• Globe or Angle Pattern• Every Valve Factory-Tested
The Cla-Val Model 100-20 Hytrol Valve is a hydraulically operated,diaphragm actuated, globe or angle pattern valve. It consists of threemajor components: body, diaphragm assembly and cover. Thediaphragm assembly is the only moving part.
The diaphragm assembly is guided top and bottom by a precisionmachined stem which utilizes a non-wicking diaphragm of nylon fab-ric bonded with synthetic rubber. A resilient synthetic rubber disc,retained on three and one-half sides by a disc retainer, forms a drip-tight seal with the renewable seat when pressure is applied abovethe diaphragm.
The reduced cavitation characteristics of the 100-20 Hytrol Valve isthe basis for the Cla-Val 600 Series. The rugged simplicity of designand packless construction assure a long life of dependable, trouble-free operation. It's smooth flow passages and fully guided disc anddiaphragm assembly assure optimum control when used in pipingsystems requiring remote control, pressure regulation, solenoidoperation, rate of flow control or check valve operation.
Available in various materials and in a wide range of sizes. It's appli-cations are unlimited.
100-20
Principle of Operation
Full Open OperationWhen pressure in the cover chamberis relieved to a zone of lower pres-sure, the line pressure at the valveinlet opens the valve, allowing fullflow.
Modulating ActionThe valve holds any intermediateposition when operating pressure isequal above and below thediaphragm. Using a Cla-Val“Modulating” Control will allow thevalve to automatically compensatefor line pressure changes.
Tight Closing OperationWhen pressure from the valve inletis applied to the cover chamber, thevalve closes drip-tight.

Do not use withtemperatures above 175° F.
Dura-Kleen® Stem - suffix KDThis stem is designed for applicationswhere water supplies containing dissolvedminerals create deposits that build-up on astandard stem and hamper valve opera-tion. A patented self-cleaning design onthe stem allows all valve sizes to operatefreely in the harshest conditions.
Delrin® Sleeved Stem - suffix KGThe Delrin® sleeved stem is designed forapplications where water supplies contain
dissolved minerals which can formdeposits that build up on the valve stemand hamper valve operation. Scale build-upwill not adhere to the Delrin® sleeve stem.Delrin® sleeved stems are not recommend-ed for valves in continuous operation wheredifferential pressures are in excess of 80 psi(2" and larger Hytrol valves).
Water Treatment Clearance - suffix KWThis additional clearance is beneficial inapplications where water treatment com-pounds can interfere with the closing of thevalve. The smaller outside diameter discguide provides more clearance betweenthe disc guide and the valve seat. Thisoption is best suited for valves used in on-off (non-modulating) service.
Viton® Rubber Parts - suffix KBOptional diaphragm, disc and o-ring fabri-cated with Viton® synthetic rubber. Viton® iswell suited for use with mineral acids, salt
solutions, chlorinated hydrocarbons, andpetroleum oils; and is primarily used in hightemperature applications up to 250° F. Donot use with epoxy coatings above 175° F.
Heavy Spring - suffix KHThe heavy spring option is used in applica-tions where there is low differential pres-sure across the valve, and the additionalspring force is needed to help the valveclose. This option is best suited for valvesused in on-off (non-modulating) service.

Service and InstallationCla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other positionsare acceptable. Due to component size and weight of 10 inch and larger valves, installation with cover UP is advisable. We recommend isolationvalves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should be consideredessential. A regular maintenance program should be established based on the specific application data. However, we recommend a thoroughinspection be done at least once a year. Consult factory for specific recommendations.

Principle of Operation
Model 100-42 Valvein Closed Position
Upstream pressure is introduced to thecontrol chamber (the chamber formedbehind the liner) of the Cla-Val Model100-42 Roll Seal valve through the con-trol piping and restrictor. When the pilotis closed, full inlet pressure is suppliedto the control chamber, thus balancingthe force developed by inlet pressureacting on the upstream face on theliner. Under these conditions, the linerremains in the fully closed position.Since the operating pressure in thecontrol chamber is greater than the out-let pressure, an additional closing forceis developed across the liner, pressingthe liner against the surrounding slottedgrillwork area and seating surface.
Model 100-42 Valve in Partially Open Position
As loading pressure is lowered slightlybelow inlet pressure, the central portionof the liner is forced to invert and cometo rest against the tip of the controlchamber cavity. Reducing the loadingpressure further (but still higher thanoutlet pressure) causes the liner todrape over the cone shaped portion ofthe control chamber cavity. This actioncauses the outer section of the liner toroll off the seating surface and a portionof the grillwork to partially open thevalve.
Model 100-42 Valve in Fully Open Position
The valve is fully opened when loadingpressure is sufficiently reduced to allowthe liner to roll back completely andexpose the full slot area. Restoringloading pressure reverses the linerrolling action to return the liner to thefully closed position.

The Cla-Val Model 100-42 Roll Seal valve is a hydraulically operated valve usedto control liquid flow by means of a flexible control element: the liner.The basic valve consists of only two parts: a one piece, investment cast bodyand an elastomeric liner. The valve body is constructed with internal ribs andslots forming a grillwork which surrounds the liner to provide support. A normallyclosed type valve is formed by the installed liner which covers the grillwork andseats against the raised seating surface in the valve body.Upstream pressure actuates the valve to produce valve opening by rolling theliner off the seating surface and the slotted grillwork.The valve is actuated by upstream pressure as the loading pressure (pressuresupplied to the control chamber) is varied by an external pilot control system.A typical pilot control system used to operate the Model 100-42 valve consistsof a restriction and a suitable pilot connected to the valve.

The Cla-Val Model 100-43 Tubular Diaphragm Valve is a pressure-operated, in-line axial valve. A tube diaphragm actuates the valve,which is comprised of three major components: 1) Tube 2) Barrier and3) Body. There is only one moving part in the valve — the tubediaphragm. There are no shafts, packing, stem guides or springs.The tube diaphragm is a one piece, homogeneous nitrile rubber partwhich is extremely durable. The ends of the tube are thick solid rubber,designed to fit between mating flanges. This design eliminates the pos-sibility of cutting the tube diaphragm due to over-tightening or pipingmisalignment during installation.The tube forms a drip tight seal around the barrier when the pressureis equalized between the valve inlet and the control chamber. Whenpressure is removed from the control chamber, the valve is open. Theminimum recommended operating pressure is 40 P.S.I. of inlet pressure.
Modulating ActionThe valve tube diaphragm holds any inter-mediate position when a quantity of wateris exhausted from the control chamber viathe pilot. The quantity of water in the con-trol chamber is established by the “setpressure” of the pilot.The control chamber is filledor exhausted to atmosphere,maintaining “set pressure.”
Principle of Operation
Full Open OperationThe valve opens when pilot set
pressure is reached and pressurein the control chamber is relieved.
Tight Closing OperationWater pressure (equal to inlet pres-sure) from valve inlet or fromupstream of valve is applied to thecontrol chamber. Valve closes bub-ble tight.

Valve Sizing Coefficient - CvA very useful expression often used in determining the head loss and/or flow rate capacity of con-trol valves is the Cv factor. Commonly referred to as the flow coefficient or valve sizing coefficient,this empirically determined factor describes the flow capacity of a valve.
The Cv factor is defined as the number of U.S. gallons per minute of water (at 60°F flowing temper-ature) discharged through a flow restriction with a head loss of one psi. In the case of a control valve,the Cv value is normally stated for the valve in the fully open position. For conditions other than fullopen, (i.e. modulating valves), contact Cla-Val Technical Services.
CV Factors
NOTE:The flow rate vs. head loss data presented here is based on a fully open valve condition.The maximum recommended velocity is 20 ft./sec.

• All 316 Stainless Steel
• Reduced Cavitation Design
• Drip-tight, Positive Sealing Action
• Service Without Removal From Line
• Every Valve Factory Tested
• Three-Year Warranty
The Cla-Val Model 100-44 Hytrol 316SS Valve is a hydraulically operated,diaphragm actuated, globe pattern valve with all 316 Stainless Steel metalparts. Specially designed 316 Stainless Steel removable slip-on flanges pro-vide 150 or 300 ANSI class flange connections that meet ANSI and ISO stan-dards. This valve is ideal for control valve applications where fluid compati-bility is often a problem. The standard Electropolish finish on the 316Stainless Steel parts offers extreme corrosion resistance to many industrialfluids such as seawater, high alkyl or high acid concentrations or otheraggressive or corrosive fluids.
The Model 100-44 Hytrol consists of these major components: body, flanges,diaphragm assembly and cover. The diaphragm assembly is the only mov-ing part and is guided top and bottom by a precision-machined stem. A non-wicking diaphragm of nylon fabric reinforced-synthetic rubber creates the con-trol chamber for the valve. A resilient, synthetic rubber disc forms a drip-tightseal, with the renewable seat, when pressure is applied to the control cham-ber. The rugged simplicity of design and packless construction assure a longlife of dependable, trouble-free operation. Smooth flow passages and fullyguided diaphragm assembly assure optimum control, when used in pipingsystems requiring remote control, pressure regulation, solenoid operation,rate of flow control or check valve operation.
100-44
Principle of Operation
Full Open OperationWhen pressure in the cover chamber isrelieved to a zone of lower pressure,the line pressure at the valve inletopens the valve, allowing full flow.
Modulating ActionThe valve holds any intermediateposition when operating pressure isequal above and below thediaphragm. Using a Cla-Val“Modulating” Control willallow the valve to automati-cally compensate for linepressure changes.
Tight Closing OperationWhen pressure from the valve inletis applied to the cover chamber, thevalve closes drip-tight.

The Cla-Val Model 800GS Deluge Valve is a pressure operated, in-line axial valve. A tube diaphragm actuates the valve, which is com-prised of three major components: 1) Tube 2) Barrier and 3) Body.There is only one moving part in the valve - the tube diaphragm.Thereare no shafts, packing, stem guides or springs.The tube diaphragm is a one piece, homogeneous nitrile rubber partwhich is extremely durable. The ends of the tube are thick solid rubber,designed to fit between mating flanges. This design eliminates thepossibility of cutting the tube diaphragm due to over-tightening or pip-ing misalignment during installation.The tube forms a drip tight seal around the barrier when the pressureis equalized between the valve inlet and the control chamber. Whenpressure is removed from the control chamber, the valve is open. Theminimum recommended operating pressure is 40 P.S.I. of inlet pressure.
Principle of Operation
Full Open Operation
When pressure in control chamberis relieved, the valve is open.
Tight Closing Operation
Water pressure from valve inlet isapplied to the control chamber. Valvecloses bubble tight.

• U.L. Listed / U.L.C. Listed• Globe or Angle Pattern• Proven Reliable Design
The Cla-Val Model 100G/2100G Deluge Valve is designed for use in controllingwater flow to Deluge, Pre-Action, or Foam-Water type fire protection sprinklersystems. This valve is U.L. Listed in "Special Systems Water Control ValvesClass I (VLFT)".The Model 100G-2100G is a hydraulically-operated, diaphragm-actuated, globeor angle pattern Deluge Valve. It consists of three major components: the body,the cover, and the diaphragm assembly. The only moving part is the diaphragmassembly. Packless construction and simplicity of design assures long servicelife and dependable low maintenance for this valve. All ferrous parts are fusionepoxy coated internally and externally for added corrosion resistance, along witha delrin sleeve stem and teflon coated removable seat.
Typical ApplicationThe Model 100G/2100G is installed to control the water flow to the
sprinklers in Deluge, Pre-Action, or Foam-Water type systems. Asimplified system is used to illustrate typical operation.
The Model 100G/2100G Deluge Valve (3) ismaintained in the closed position by means ofsystem water pressure controlled by a pilotcontrol (4). When the pilot control valvereceives a signal from the fire detection sys-tem, it allows the deluge valve to open.Firefighting water (1) then enters systempiping (5) and discharges fromsprinklers (6).

• Drip - tight, positive seating• Service without removal from line• Threaded or flanged ends• Globe or angle pattern• Every valve factory-tested
The Cla-Val Model 100S/2100S Seawater Service Hytrol Valveis a hydraulically operated, diaphragm actuated, globe or anglepattern valve. It consists of three major components: body,diaphragm assembly and cover. The diaphragm assembly isthe only moving part.
The body (ductile iron or cast steel) is epoxy coated and containsa removable seat insert. The diaphragm assembly is guided topand bottom by a precision machined stem. It utilizes a non-wick-ing diaphragm of nylon fabric bonded with synthetic rubber. Aresilient synthetic rubber disc retained on three and one half sidesby a disc retainer forms a drip-tight seal with the renewable seatwhen pressure is applied above the diaphragm.
The Model 100S/2100S Seawater Service Hytrol Valve is thebasic valve used for seawater applications. It is the valve ofchoice for system applications requiring deluge, pressure regu-lation, pressure relief, solenoid operation, rate of flow control, liq-uid level control or check valve operation. The rugged simplicityof design and packless construction assure a long life ofdependable, trouble-free operation. It is available in variousmaterials and in a full range of sizes, with either threaded orflanged ends. Its applications are unlimited.
Modulating ActionThe valve holds any intermediate positionwhen operating pressures are equal aboveand below the diaphragm. A Cla-Val “modu-lating” pilot control will allow thevalve to automatically compen-sate for line pressure changes.
Principle of Operation
Full Open OperationWhen pressure in the cover chamberis relieved to a zone of lower pres-sure, the line pressure at the valveinlet opens the valve, allowing full flow.
Tight Closing OperationWhen pressure from the valve inletis applied to the cover chamber, thevalve closes drip-tight.

Cla-Val Control Valves operate with maximum efficiency when mounted in horizontal piping with the main valve cover UP, however, other posi-tions are acceptable. Due to component size and weight of 8 inch and larger valves, installation with cover UP is advisable. We recommendisolation valves be installed on inlet and outlet for maintenance. Adequate space above and around the valve for service personnel should beconsidered essential. A regular maintenance program should be established based on the specific application data. However, we recommenda thorough inspection be done at least once a year. Consult factory for specific recommendations.

• Packless design--no lubrication• Precisely engineered--close drip-tight• Full line-sized opening--low flow resistance• No internal or external orifice• Diaphragm is fully supported for longer life• Movable parts & seat ring replaceable without
removing valve from line
The Cla-Val Model 7100 Valve is a diaphragm actuated, hydraulicallyoperated valve designed for low original cost and long life. Its simple,rugged construction allows it to perform dependably under the mostsevere operating conditions. Its compact design makes it easy to install.
The 7100 Valve is ideal for any application where the need is for On-Off control, the controlling medium of which is usually the liquid itself,passing through a remote control. The control pressure, when appliedagainst the flexible diaphragm, produces a drip-tight seal between thevalve disc and its seat. In the open position, the diaphragm assemblylifts to provide full flow.
The 7100 Valve provides all the advantages of an automatic controlvalve at a cost comparable to manual valves of the same size andquality.
Purchase Specification Valve shall be full line size, diaphragm actuated. It shall be hydraulicallyoperated by employing the fluid flowing through it to open as well asclose the valve. The diaphragm shall be fabricated of nylon reinforcedsynthetic rubber, and shall be fully supported in both the open andclosed positions and not be used as a disc or seating element. Thereshall be no packing glands, internal orifice, or continuous bleeding.
The disc shall be synthetic rubber and have a cross section retainedon 31/2 sides. The disc shall close drip-tight against the valve seat.The seat ring shall be replaceable and all necessary repairs shall bepossible without removing valve from the line. Valve shall be similar inall respects to the Model 7100 Valve as manufactured by Cla-Val,Newport Beach, California, or approved equal.

• Accurate Pressure Control• Optional Check Feature• Fast Opening – maintains line pressure• Slow Closing – prevents surges• Completely Automatic Operation
The Cla-Val Model 50-01/650-01 Pressure Relief Valve is a hydraulicallyoperated, pilot-controlled, modulating valve designed to maintain con-stant upstream pressure within close limits. This valve can be used forpressure relief, pressure sustaining, back pressure, or unloading func-tions in a by-pass system.
In operation, the valve is actuated by line pressure through a pilot controlsystem, opening fast to maintain steady line pressure but closing gradu-ally to prevent surges. Operation is completely automatic and pressuresettings may be easily changed.
If the optional check feature “D” is added, and a pressure reversal occurs,the valve closes to prevent return flow.

Pressure Sustaining ServiceWhen installed in a line between an upper zone and alower area of heavy demand, the valve acts to maintain desiredupstream pressure to prevent "robbing" of the upperzone. Water in excess of pressure setting flows to areaof heavy demand; control is smooth, and pressure reg-ulation is positive.
Pressure Relief ServiceTo provide protection for the system against high pressure surgeswhen pumps are shut down, this fast opening – slow closing reliefvalve dissipates the excess pressure.

• Accurate Pressure Control• Wide Adjustment Ranges• Optional Check Feature Available• Quick Acting Solenoid Shutoff• Easy Installation and Maintenance
The Cla-Val Model 58-01/658-01 valve performs two separate functions. Itmaintains a constant back pressure by discharging excess pressure down-stream and when the solenoid is activated the valve closes drip tight.
In operation, the valve is actuated by hydraulic line pressure through thepilot control system. When inlet pressure is greater than the control set-ting, the valve opens. When inlet pressure is equal to the control setting,the pilot modulates the valve maintaining the pre-selected back pres-sure. When inlet pressure is less than the control setting, the pilot sys-tem closes the valve drip tight. Changing the pressure setting simplyinvolves turning an adjusting screw on the pilot control.
The solenoid control is available in energize to open or de-energizeto open models.
Back Pressure Maintenance ServiceA frequent application of this valve is to maintain minimumback pressure in the system while supplying water toa reservoir. The electrode in the storage tank activatesthe solenoid shutoff feature when the tank reaches apre-set level.
Electronic Control ServiceUsing a timer connected to the solenoid control of the valve, flowfrom the high pressure system to the low pressure system can becontrolled at certain times during the day.

750-01Pressure Relief, Sustaining & Back Pressure Valve
Description The Cla-Val Model 750-01 is a hydraulically operated pilot actuatedautomatic control valve for pressure sustaining, relief and/or backpressure service.The main valve consists of only two parts, a stainlesssteel body and an elastomeric liner or control element.
The main valve will open when inlet pressure begins to exceed a presetpressure and will allow enough flow to maintain that inlet pressure. Inpressure sustaining service, Model 750-01 will conserve pressure inan upper system during periods of high demand in a system below. Inpressure relief service, the Model 750-01 will modulate to exhaust linepressure to keep it below a set point maximum. On a pump bypasssystem, the valve will allow flow back to the pump suction when pumpdischarge pressure exceeds the set point.
Cla-Val Model 750-01 will control from no flow to full open flow withoutany chattering or slamming under low flow conditions. For this reason,on by-pass, relief, and pressure sustaining service, there is never aregion of control instability. There is no slip-type friction because thevalve has no bearings. Cla-Val Model 750-01 valves have excellentresistance to cavitation with a Cf factor of 0.9.These valves can be supplied as combination control valve withcheck. Pilot controls, options, and accessories are fully piped at thefactory and the Cla-Val Model 750-01 is shipped ready for installation.
Purchase Specification Valve and control system shall maintain inlet pressure at a predeterminedset point; shall open as pressure starts to increase above the setpoint, and close as pressure falls below the set point. Control valveshall be constructed of two parts: a stainless steel body and anelastomeric liner or control element. Minimum rangability shall be500:1 based on capacity at flowing pressure conditions. Cf shall begreater than or equal to 0.9. Valve and control system shall be similarin all respects to Cla-Val Model 750-01 as manufactured by Cla-Val,Newport Beach, California.

On a chill water circulating loop system the 250-01/605-01Differential Pressure Relief Valve is installed between loop supplyand return lines to maintain a constant differentialacross the loop. The loop differential pressure remainsconstant regardless of the loop demand change there-by increasing cooling system efficiency.
• Accurate Differential Pressure Control• Controls Maximum Flow Through Pumps• Circulating Loop Flow Control• Completely Automatic Operation
The Cla-Val Model 250-01/605-01 Differential Pressure Relief Valve isa hydraulically operated, pilot controlled, modulating valve. It isdesigned to maintain a constant pressure differential between any twopressure points in a system where the closing of the valve directly caus-es the differential pressure to increase. The valve tends to open on anincrease in differential pressure and close on a decrease in differentialpressure.
In operation, the valve is actuated by line pressure through a pilot con-trol system sensing from two points across which a differential is to bemaintained. Operation is completely automatic and pressure settingsmay be easily changed.

790-01
DescriptionThe Cla-Val Model 790-01 is a hydraulically operated, pilot actuatedautomatic control valve for pressure reducing service. The mainvalve consists of only two parts: a stainless steel body, and anelastomeric liner or control element.
Pressure reducing valves are used to lower pipeline pressure to apredetermined set point. Cla-Val Model 790-01 automaticallycontrols downstream pressure, from no flow to full open flow, withoutregard to changes in inlet pressure. Outlet pressure control issmooth and precise since the friction and hysteresis of the valve andpilot is negligible.
Because the valve will not chatter or slam under low flow conditions,it is not necessary to parallel Cla-Val Model 790-01 with a secondsmaller size control valve to obtain accurate pressure control at lowflow rates. In any size, Cla-Val Model 790-01 will control pressureright down to shutoff.
Pressure reducing valves can be supplied as a combination withcheck valve. Control systems are fully piped at the factory and theCla-Val Model 790-01 is shipped ready for installation.
Purchase SpecificationValve and control system shall lower line pressure to a predeterminedset point and shall maintain that set point regardless of variations inflow or inlet pressure. Control valve shall be constructed of twoparts: a stainless steel body, and an elastomeric liner or control element.Minimum rangability shall be 500:1 based on capacity at flowingpressure conditions. Cf shall be greater than or equal to 0.9. Valveand control system shall be similar in all respects to Cla-Val Model790-01 as manufactured by Cla-Val, Newport Beach, California.

• Modulating Control• Maintains Constant Outlet Pressure Over a
Wide Range of Flows• Durable Construction• Convenient — Space Saver
The Cla-Val Model 90-48/690-48 Pressure Reducing Valve with LowFlow By-Pass automatically reduces a higher inlet pressure to asteady lower downstream pressure regardless of changing flow rate.The low flow by-pass capability is achieved by using the Cla-ValModel CRD-40 Direct Acting Pressure Reducing Valve as an integralpart of the main valve. By doing this, space is saved and installationand maintenance become much easier.
The pressure reducing valve is hydraulically operated and controlledby a Cla-Val CRD pilot control, which senses pressure at the mainvalve outlet. An increase in outlet pressure forces the CRD pilot con-trol to close and a decrease in outlet pressure opens the control.Thiscauses the main valve cover pressure to vary, modulating the mainvalve and thereby maintaining constant outlet pressure.
The Model CRD-40 low flow pressure reducing by-pass is preset toa higher pressure than the CRD pilot control. The CRD-40 respondsto pressure changes at the main valve outlet. When the CRD closes,the Model CRD-40 remains open allowing low flow, to by-pass themain valve. The CRD-40 closes when the flow decreases and thedownstream pressure reaches its set point .

The pressure reducing control responds to slight variations in down-stream pressure and immediately repositions the main valve tomaintain the desired downstream pressure.The pressure sustainingcontrol is normally held open by the upstream pressure, but closesshould the pressure drop to the control set point. This in turn closesthe main valve to sustain the desired upstream pressure.
If a check feature is added, and a pressure reversal occurs, thedownstream pressure is admitted into the main valve cover chamberand the valve closes to prevent return flow.

990Balanced Direct ActingPressure Reducing Valve
Typical Applications
High rise buildings use 990 Pressure Reducing Valvesin various water systems (potable water, boiler feedair conditioning, etc.) to control pressure fluctuations betweenfloors.
Industrial plants use 990 Pressure Reducing Valves betweena high pressure supply system and equipment requiring lowerpressure. Typically 990 Pressure Reducing Valves are used atsupply connections for water heaters, boiler feed water orother process water systems.
Municipal water systems use 990 Pressure Reducing Valvesat service connections in a high pressure distribution zone.
Depending on flow requirements, 990's may be installed inparallel. One 990 provides desired outlet pressure while thesecond 990 handles low flow conditions. If necessary, addi-tional 990's can be added for more flow capacity. Also, the 990is ideal for a low flow bypass around a larger Cla-Val 90 SeriesPressure Reducing Valve.
• Balanced, Single Seat Design• Operates In Any Position• Easy Installation• Stainless Steel Trim Standard• Gauge Connections Standard• All Bronze Body and Cover
The Cla-Val Model 990 Pressure Reducing Valve automaticallyreduces a higher inlet pressure to a steady lower downstream pres-sure due to unique balanced design. This valve is an accurate regu-lator capable of holding downstream pressure to a predeterminedamount, regardless of upstream pressure fluctuations.
Periodic maintenance consist of regular cleaning of internal strainerthat is accessed by removing bottom plug. There are no user serv-iceable components.

• Accurate and Repeatable Level Control• Proportional Flow• Reliable Hydraulic Operation• Drip Tight Positive Shut-off• Completely Automatic Operation
The Cla-Val Model 129-01/629-01 Float Valve maintains a relativelyconstant level in storage tanks and reservoirs by admitting flow into thetank in direct proportion to the flow out of the tank. It is a hydraulicallyoperated, pilot controlled, diaphragm valve. The rotary disc type floatoperated pilot control is installed at the high liquid level in the reservoirand is connected via tubing or pipe to the main valve. As the liquid levelchanges, the float control proportionally opens or closes the mainvalve, keeping the liquid level nearly constant. If the check featureoption is added and a pressure reversal occurs, the downstream pres-sure is admitted into the main valve cover chamber and the valve clos-es to prevent return flow.
The "D" feature on a vertically installed 6" andlarger valve must be horizontally installed.

• Accurate Level Control• Completely Automatic Operation• Simple Operation• Drip-Tight Shut-Off• Easy Installation and Maintenance
The Cla-Val Model 428-01/628-01 Float Valve modulates to maintain aconstant liquid level in a storage tank by compensating for variations insupply or demand. It can be installed to control the flow into or out of thetank by either closing on a rising level or opening on a rising level. Thisvalve is a hydraulically-operated, pilot-controlled diaphragm valve.
The Pilot Control System consists of an integral variable orifice in the mainvalve cover and a remotely mounted float control. A slight change in liquidlevel moves the float control. This action varies the pressure in the valvecover, causing the main valve to seek a new position. The integral variableorifice automatically regulates the flow into the cover chamber until thevalve reaches a position that is in direct relation to the position of the floatcontrol.

The Model 133-01/633-01 Metering and Flow Rate Controller is typically installed ina fluid delivery system where the flow rate is measured or changed from a remotelocation such as a SCADA system.
The Cla-Val Model 133-01/633-01 Metering Valve is a completely selfcontained valve and control system that accurately meters and/or con-trols flow rate when used on valves with pressure differentials of less than100 PSID.Using a 131VC-3 Cla-Val Microprocessor, data from differential pressureand position transmitters are assimilated into a proprietary algorithm pro-gram that is based on valve size and configuration to arrive at a flowmeasurement. This information can then be used for retransmissionand/or compared with a local or remote set point for valve flow control.The 131VC-3 Control System can also be installed on new or existinghydraulic pilot control valves such as: pressure reducing, pressure sus-taining, flow limiting and level control to transmit flow rate without dis-turbing the valves primary hydraulic function(s). Specify 131VC-3KT Kitfor these applications.For all applications, specify voltage, minimum / maximum pressures &flow rates, valve size, pressure class and optional features. Consult yourlocal representative or the factory for engineering assistance and valveselection if required.
Please refer to the 131VC “Electronic Control Systems” brochurefor specific information regarding valve theory of operation, stan-dard & optional features, control parameters and electrical compo-nent specifications.

The valve is designed to be used with supervisory control systems havinga isolated remote analog setpoint output and a process variable upstreampressure input. When installed in a line between an upper zone and alower area of demand, the valve acts to maintain desired upstream pressureto prevent “robbing” of the upper zone. Water in excess of pressure settingflows to area of demand, control is smooth, and pressure regulation ispositive.It is also an effective solution for lowering costs associated with “confinedspace” requirements by eliminating need for entry into valve structure forsetpoint adjustments and system information.Additional Pilot Controls, hydraulic and/or electronic, can be easily addedto perform multiple control functions to fit exact system requirements.

The CRD-31 consists of a hydraulic pilot and integral controller thataccepts a 4-20 mA remote setpoint and precisely positions the pilot tomaintain a valve outlet pressure within a predetermined zero and span set-ting. Default settings are set to minimum spring range adjustment at 4 mAand maximum at 20 mA. Pressure settings are linear between these val-ues. Optional Range Parameter Kit is required to change pressure rangelimits.
A separate pressure sensor signal (customer supplied) may also be sentto a supervisory control system for verification of pressure setting.
Continuous internal monitoring (pat. pend) of actuator position results inaccurate pressure changes with no backlash or dithering. Built-in elec-tronic limits prevent over ranging. In the event of a power or control inputfailure, the CRD-31 pilot remains in hydraulic control assuring system sta-bility under changing conditions.

CLA-VAL ECO-TIMER and ECO-SWITCH
• Compact• Multi-Functional• Tamper-Proof Programming
The Cla-Val ECO-TIMER and ECO-SWITCH are stand-alone elec-tronic valve controllers designed for many water system control appli-cations, including flushing a filter screen on a regular time basis, con-trolling a reservoir level or controlling water flow in pressure man-agement systems.
They consist of an internal clock with an operating program, one sole-noid output and two independent contact inputs (ECO-SWITCH only)in a waterproof enclosure. The enclosure has an "Action Zone"(magnetically activated) for manual override and LED's displayingvalve operation state and battery condition. The ECO-SWITCH hastwo additional external inputs for remote signaling valve operation.The ECO-TIMER and ECO-SWITCH use a three-way latching sole-noid pilot valve to control the Cla-Val control valve. Depending on theapplication, the ECO-TIMER and ECO-SWITCH are programmed tocontrol the valve to be open-closed or to be switched between two dif-ferent control set points. Safe operation is assured with internal bat-tery-operation.
The ECO-TIMER and ECO-SWITCH use a separate programmerdevice connected only when program changes are necessary.Programming information is downloaded using intrinsically safeinfrared signals. Once programmed, the device is disconnected toprevent unauthorized changes. After programming, the ECO-TIMERor ECO-SWITCH can control the Cla-Val valve with any combinationof internal timing sequences, external switch inputs, or manual"Action Zone" inputs.
THREE PROGRAMMABLE MODES
• Time ControlOne to four time periods (minimum one-minute increment) of valve activation programmed for up to seven days per week.
• Remote ControlTwo inputs allow valve control separate from time control mode using remotely located switches.

Series 582 Pressure Loss Curve
The Cla-Val Series 582 Two-Door Wafer Check Valve has torsionsprings that force the two doors to shut before flow reversal, reduc-ing the water hammer potential that normally occurs with single-door swing check valves. To help reduce water hammer, thetwo-door design also reduces the travel distance from open toshutoff for a quicker response. Extremely short in lay length, thevalve is both a compact and an economical solution. Two-DoorWafer Check Valves are available in sizes 2” to 48” with either a125 lb. or 250 lb. pressure class rating.
Although lighter in weight than globe style swing check valves,Cla-Val Two-Door Wafer Check Valves are designed for heavy-dutyapplications. For ease of installation, valves 6” and larger aresupplied with a tapped hole for installing a lifting eye bolt. Allmaterials conform to ASTM specifications, ensuring long lastingreliable performance. As a confirmation of Cla-Val’s commitmentto quality, 2” to 12” 125 lb. class Series 582 valves are FactoryMutual approved.

Cla-Val “Tite Seal” foot valves provide years of trouble free opera-tion at low or high pressures. The special Buna-N® seal allows ini-tial contact to the metal plug, for zero leakage, then as pressurebuilds, the Buna-N® seal is compressed only slightly until the plugfully contacts the metal seat preventing further compression ofthe Buna-N® seal. In this manner the seal cannot be damagedfrom compression and pump prime is always assured. A 360degree stainless steel strainer (not plated steel) is providedstandard with at least, three times flow-thru area of the foot valvesize. This greatly enlarged flow thru area strainer means full flowcan be maintained even should some small particles collectagainst the strainer. Cla-Val “Tite Seal” Foot Valves provide non-shock and silent shut-off.

• Simple Proven Design• No-Slam Operation• Drip Tight Shut Off• Dual Speed Control• No Packing Glands or Stuffing Boxes• Available in a Variety of MaterialsThe Cla-Val Model 81-02/681-02 Check Valve is a hydraulically operatedNo-Slam Check Valve with dual speed controls. This valve opens when thepressure at the inlet exceeds the discharge pressure. A gradual rate ofopening prevents sudden opening surges. When a pressure reversaloccurs the higher downstream pressure is applied to the cover chamberthrough the control tube lines, and the valve closes drip tight.
This valve is ideally suited for use where a positive shutoff is required. Therubber disc assures tight sealing even if the fluid contains grit or othersmall-size particles. The simple packless design insures reliable operationand freedom from leaks.
Note: The effectiveness of this valve is related to pipeline velocity. We rec-ommend a maximum flow based on pipeline velocity of 6 feet per second.If pipeline velocities exceed 6 feet per second, consideration should begiven to adding a Cla-Val Model 50-01 Pressure Relief Valve or a Cla-ValModel 52 Series Surge Control Valve to the system.

The Cla-Val Model 60-11/660-11 Booster Pump Control Valve is apilot-operated valve designed for installation on the discharge ofbooster pumps to eliminate pipeline surges caused by the startingand stopping of the pump.
The pump starts against a closed valve. When the pump is start-ed, the solenoid control is energized and the valve begins to openslowly, gradually increasing line pressure to full pumping head.When the pump is signaled to shut-off, the solenoid control is de-energized and the valve begins to close slowly, gradually reducingflow while the pump continues to run. When the valve is closed, alimit switch assembly, which serves as an electrical interlockbetween the valve and the pump, releases the pump starter andthe pump stops.
Should a power failure occur, a built-in lift-type check valve closesthe moment flow stops, preventing reverse flow regardless of sole-noid or diaphragm assembly position.

• Prevent Surges in Pipelines• Simple Hydraulic Operation• Adjustable Opening & Closing Speeds• Solenoid Control Can Be Operated Manually• Proven Reliable Design
The Cla-Val Model 61-02/661-02 Deep Well Pump Control Valveis designed to protect pipelines from surges caused by the start-ing and stopping of deep well pumps.This is a hydraulically oper-ated diaphragm valve which is controlled by a solenoid pilotvalve. Separate adjustable flow control valves in the pilot systemregulate the opening and closing rates. A limit switch on thevalve stem serves as an electrical interlock between the valveand the pump motor.
The operation of the valve is completely automatic and con-trolled by the solenoid valve. With the pump off, the valve is wideopen. When the pump is started, the solenoid is energized andthe valve begins to close slowly, discharging air and the initialrush of sand and water from the pump column to atmosphere. Asthe valve closes the pump output is gradually diverted into themain line preventing the development of a starting surge.
When it is time to shut off the pump the solenoid is de-energized.The pump continues to run while the pump control valve opensslowly diverting pump output to atmosphere. As pump pressuregradually decreases the main line check valve closes slowly, pre-venting shock or slam during the pump stopping cycle. When thepump control valve is wide open the limit switch assemblyreleases the pump starter and the pump stops.

The Cla-Val 834-05 Deluge Valve is a pressure-operated, in-line axialvalve. A tube diaphragm actuates the valve, which is comprised ofthree major components: 1) Tube 2) Barrier and 3) Body. There is onlyone moving part in the valve - the tube diaphragm. There are noshafts, packing, stem guides or springs.The tube diaphragm is a one piece, homogeneous nitrile rubber partwhich is extremely durable. The ends of the tube are thick solid rubber,designed to fit between mating flanges. This design eliminates thepossibility of cutting the tube diaphragm due to over-tightening or pip-ing misalignment during installation.The tube forms a drip tight seal around the barrier when the pressureis equalized between the valve inlet and the control chamber. Whenpressure is removed from the control chamber, the valve is open. Theminimum recommended operating pressure is 40 P.S.I. of inlet pressure.
Principle of Operation
Full Open Operation
When pressure in control chamberis relieved, the valve is open.
Tight Closing Operation
Water pressure from valve inlet isapplied to the control chamber.Valve closes bubble tight.

The Cla-Val 403 Series Remote Control Valve is used where “on-off” con-trol is required. Pressure signals from a remote control “open or close” asmall auxiliary valve installed on the main valve cover, which in turn opensor closes the main valve. Only the small amount of fluid in the auxiliaryvalve cover must pass through the remote control pilot in order to fullyopen or close the larger main valve.
The Model 403 Series consists of a 100-01 Hytrol main valve and a smallHytrol auxiliary valve. Both the main valve and the auxiliary valve are sin-gle-seated, diaphragm operated globe type valves. Line pressure appliedto the auxiliary valve cover closes the main valve drip tight.

Pressure Relief Valve is designed specifically to automati-
cally relieve excess pressure in fire protection pumping sys-
tems. Pilot controlled, it maintains constant system pres-
sure at the pump discharge within very close limits as
demands change.
At pump start, Cla-Val Relief Valve modulates to relieveexcess pump capacity, maintaining positive system pres-sure at the pump discharge.
When fire demand slows or ceases, Cla-Val Model50B-4KG-1 opens, diverting entire pump output to dis-charge, allowing fire pump to be stopped without causingsurging in the lines.
(Please note that if the Model 50B-4KG-1 is to be used ona continuous duty basis to maintain fire-system pressure,suitable back pressure must be provided on the valve toprevent cavitation damage. Consult the factory for details.)

The Cla-Val Model 850B-4 Fire Relief Valve is a pressure-operated, in-line axial valve. A tube diaphragm actuates the valve, which is com-prised of three major components: 1) Tube 2) Barrier and 3) Body.Thereis only one moving part in the valve — the tube diaphragm. There areno shafts, packing, stem guides or springs.The tube diaphragm is a one piece, homogeneous nitrile rubber partwhich is extremely durable. The ends of the tube are thick solid rubber,designed to fit between mating flanges. This design eliminates the pos-sibility of cutting the tube diaphragm due to over-tightening or pipingmisalignment during installation.The tube forms a drip tight seal around the barrier when the pressureis equalized between the valve inlet and the control chamber. Whenpressure is removed from the control chamber, the valve is open. Theminimum recommended operating pressure is 40 P.S.I. of inlet pres-sure.
Modulating ActionThe valve tube diaphragm holds any inter-mediate position when a quantity of wateris exhausted from the control chamber viathe pilot. The quantity of water in the con-trol chamber is established by the “setpressure” of the pilot.The control chamber is filledor exhausted to atmosphere,maintaining “set pressure.”
Principle of Operation
Full Open OperationThe valve opens when pilot setpressure is reached and pressurein the control chamber is relieved.
Tight Closing OperationWater pressure (equal to inlet pres-sure) from valve inlet or fromupstream of valve is applied to thecontrol chamber. Valve closes bub-ble tight.

The Model 55L is normally held closed by the force of the compressionspring above the diaphragm. When the controlling pressure appliedunder the diaphragm exceeds the spring setting, the disc is lifted off itsseat, permitting flow through the control. When control pressure dropsbelow the spring setting, the spring forces the control back to its normal-ly closed position. The controlling pressure is applied to the chamberbeneath the diaphragm through an external tube on the 55L.
Pressure adjustment is simply a matter of turning the adjusting screw tovary the spring load on the diaphragm. The 55L is available in two pres-sure ranges; 0 to 75 psi, 20 to 200 psi. To prevent tampering, the adjust-ment cap can be wire sealed by using the lock wire holes provided in thecap and cover.

• Accurately Monitors Valve Position
• Environmentally Sealed to IP-68
• Featured on Electronic Control Valves
• Easy Field Adjustments
• Compact and Rugged Construction
The Cla-Val Model X117D Valve Position Transmitter is an accuratemonitor of valve position. Through an industry standard 4-20 mAoutput, the X117D delivers the accuracy required for computer-guided control valve systems (SCADA type). The electronic com-ponents are enclosed in a rugged, sealed aluminum and stainlesssteel housing. The assembly is mounted externally on the cover ofa Cla-Val main valve. An extension of the valve stem projects out-side of the cover at the center boss and is mechanically linked tothe electronic components with an extensible wire rope. As thevalve stem rises and lowers, the X117D provides an output signalin direct proportion to the valves position. An internal spring main-tains constant tension on the wire rope for virtually no hysteresis errorthroughout valve stroke.
Typical InstallationWiring DiagramThe signal from the position sensing mechanism wire rope isconverted to a two-wire 4 to 20 mA current output. The voltagecompliance range is 14 to 35 VDC. The required, but not sup-plied, maximum load resistance can be calculated using thefollowing formula:

Valve and Control
The Cla-Val Model CF1-C1 Float Control is a float-actuated multiportpilot control which provides non-modulating, two-position, on-offoperation. It is used primarily to operate remotely located Cla-Valvalves requiring three-way or four-way pilot valve operation.Designed for used in open tanks, this control operates on a mini-mum level change of approximately 1". Maximum level change is19". This level adjustment can be located up to 111⁄2 feet from thecontrol by adding float rod extensions.
The float moves freely on the float rod. On rising liquid level, the floatcontacts the upper stop and lifts the float linkage to the "UP" posi-tion. As the liquid level lowers, the control stays in the "UP" positionuntil the float contacts the lower stop. The control then shifts to the"DOWN" position.

Pressure Reducing Control Valves• Direct Acting• Hydraulic or Pneumatic Operation• Simplified Design, Easy Adjustments• Operates in Any Position• Gauge Connection Port
The Cla-Val Models CRA and CRD Pressure Reducing Control auto-matically reduce a higher inlet pressure to a lower outlet pressure.They are direct acting, spring loaded,diaphragm type control regula-tors that operate hydraulically or pneumatically. These valves are heldopen by the force of the compression spring above the diaphragm, andclose when the downstream pressure acting on the underside of thediaphragm exceeds the spring setting. The CRD senses downstreampressure directly and the CRA senses downstream pressure remote-ly.
Flow through the control responds to changes in downstream pres-sure. Turning the adjusting screw clockwise increases the deliverypressure, and turning it counterclockwise decreases the pressure. Aresilient disc assures tight shut-off on dead-end service.
The Model CRA and CRD may be installed in any position. There isone inlet port and two outlets for either straight or angle installation.The second outlet port can be used for a gauge connection.
These valves are ideal small capacity regulators for applications suchas water coolers, fountains, humidifiers, gas refrigerators, and air sup-ply to tools and instruments (remote pressure sensing is available withthe CRA). They also have numerous applications as pilot controls onmany Cla-Val Automatic Control Valves.

• Direct Acting - Precise Pressure Control• Positive Dependable Opening• Drip Tight Closure• No Packing Glands or Stuffing Boxes• Sensitive to Small Pressure Variations
The Cla-Val Model CRL and 55F Pressure Relief Valves are direct-act-ing, spring loaded, diaphragm type relief valves. Often used as pilot con-trols for Cla-Val hytrol valves, they can also be used as self-containedpressure relief valves. These valves may be installed in any position andopen and close within very close pressure limits.
The Model CRL & 55F are normally held closed by the force of the com-pression spring above the diaphragm; control pressure is applied underthe diaphragm.When the controlling pressure exceeds the spring setting,the disc is lifted off its seat, permitting flow through the control. Whencontrol pressure drops below the spring setting, the spring forces thecontrol back to its normally closed position. The controlling pressure isapplied to the chamber beneath the diaphragm through an external tubeon the 55F model and a sensing port on the CRL.
Pressure adjustment is simply a matter of turning the adjusting screw tovary the spring pressure on the diaphragm. The CRL & 55Fare available in three pressure ranges; 0 to 75 psi, 20 to 200 psi, and100 to 300 psi. To prevent tampering, the adjustment cap can be wiresealed by using the lock wire holes provided in the cap and cover.

Air Release &Vacuum Breaker Valve
• Sizes 1” - 4”• Automatically Protects Pipelines• Easily Serviced Without Removal from Pipeline• Simple, Effective Patented Design• Corrosion Resistant Internal Parts• Engineered For Lasting Service
Designed to protect pipelines from air lock and vacuum collapse, theCla-Val Model 33A Air Release and Vacuum Breaker Valve elimi-nates air and prevents vacuum formations in pipelines. It has a largeventing orifice and large float clearances to freely exhaust or admitair during pipeline filling or draining.
During normal pipeline operation, air accumulation and buoyancycause the float ball to lower or lift. As the water level lowers inside thevalve, small amounts of accumulated air are released through thesmall orifice. Once air is released, the patented float poppet systemcloses drip tight.
Valve servicing is simple because the entire float poppet system, canbe replaced without removal of the valve body from the pipeline.

OperationAir Release Mode—Valve is normally open.When line is filled or pump started, air is exhausted through thenormally open 33A valve.As liquid fill the valve, float ball rises to form a drip-tight closureand remaining air is exhausted through small orifice.
Note:Available for Sea Water ServiceSee Material Specifications
Vacuum Prevent Mode When line pressure drops below posi-tive pressure and the liquid level lowers, the float drops, unseat-ing the valve and allowing air into the line, thus preventing avacuum.
Installation
Series 33A Air Release and Vacuum Breaker Valves aretypically installed at high points in pipelines for air release, or atanticipated pipeline vacuum occurrence locations. Install Series33A at regular intervals (approximately 1/2 mile) along uniformgrade line pipe. Mount the unit in the vertical position on top ofthe pipeline, and include an isolation/shutoff valve.
Series 33A is often installed upstream of check valves in pumpdischarges to vent air during start-up and to allow air reentrywhen the pump stops.

• Engineered For Drip Tight Seal At Low Pressures
The Cla-Val Series 34 Air Release Valve is designed to protectpipelines from entrained air that collects at high points in a pipeline.This valve continuously eliminates air from a system by releasing smallqualities of air before large air pockets can occur. In many installations,continuing accumulations of air in the pipeline (lacking air releasevalves); causing flow capacity to slowly decrease; power consumptionslowly increases; un-noticeable at first, until flow drops dramatically,even stopping due to air blocks in the piping. Another problem result-ing from excessive air accumulation is un-explained pipeline rupture.These ruptures are passed off as the result of ground settling or defec-tive pipe, Where as in reality its large air pockets that greatly increasepressure surges (normally occurring) when flow stops and starts caus-ing the rupture. During normal pipeline operation, air accumulation atthe high point will displace the liquid within the air valve and lower thewater level in relation to the float. As level of the liquid lowers, where thefloat is no longer buoyant, the float drops and opens the valve orifice seatand permits the accumulated air to be exhausted to atmosphere. Afterair is released, the liquid level in the air valve rises and closes the valveorifice seat. This cycle automatically repeats as air accumulates insidethe air release valve, thereby preventing the formation of air pockets
Air Release Valves
InstallationSeries 34 Air Release Valves are typically installed at high-points in pipelines and at regular intervals, of approximate1/2 mile, along uniform grade line pipe.
Mount the unit in the vertical position on top of the pipelinewith an isolation valve installed below each valve in theevent servicing is required. A vault with adequate air ventingand drainage is recommended.
Note:Vacuum check valves can be supplied on the discharge ofall size air release valves to prevent air re-entering the systemduring negative pressure conditions
Purchase SpecificationsThe air release valve shall be of the float operated, simplelever or compound lever design, and capable ofautomatically releasing accumulated air from a fluid systemwhile the system is pressurized and operating.
An adjustable designed orifice button shall be used to sealthe valve discharge port with drip-tight shut-off. The orificediameter must be sized for use within a given operatingpressure range to insure maximum air venting capacity.

• Provides High Capacity Venting for Pipeline Protection
• Stainless Steel Trim Standard
• Stainless Steel Floats Guaranteed
• Fully Ported Valves - No Restrictions
• Designed For Drip Tight Seal At Low Pressures
The Cla-Val Series 35 Air and Vacuum Valve is designed to performtwo separate functions. First, it will allow large quantities of air to beexhausted from the pipeline as it is being filled with water. Whenthis air has been vented completely, water will enter the valvecausing the float to seal tightly against the seat to prevent waterflow. Secondly, if the line is being drained, either intentionally or asa result of pipeline breakage, the valve responds to the loss inpressure and opens. This allows air to re-enter the pipeline andprevents potentially damaging vacuum from developing.
Note: The Series 35 does not open under pressure to exhaustsmall quantities of air which may collect at high points duringsystem normal operation. Series 34 Air Release Valve is requiredfor this function.

• Engineered For Drip Tight Seal At Low PressuresSeries 37 Well Service Air Valves regulate air discharge from thepump column to prevent shock and air entering the system witheach start. Conversely with each pump stop, full flow unrestrictedair, is allowed back into the column preventing vacuum forming,which can damage pump steals, but also to prevent the pumprestarting against a full head in the column because vacuum willprevent the pump column to drain. Under this condition severedamage to the pump, controls and piping can occur.
All the preceding is accomplished by means of a unique air throt-tling device (double port) and an arrestor check with built in anti-shock feature.
Well service air vacuum valves, once closed and pressured do notopen to release under pressure.
See series 34 Air Release Valves page 5.

Series 37 Well Service Valves (Heavy Duty) are sup-plied with air throttling devices. These devices permitregulating the volume of air discharge from the verti-cal pump column thereby to cushion the shock fromthe rising water column, as it impacts against aclosed pump, discharge check valve or control valve.By utilizing this type air valve damage to the verticalturbine pump. Piping and controls will be prevented.Field adjustment of this air throttling device is quitesimple and requires no special tools.Note: Light duty well service valves are supplied with-out air throttle device. Instead it is fitted with a waterdiffuser that function like a water faucet bubbler tobreak down a solid column of water into smallstreams there by allowing the water to raise the airvalve float slowly into the closed position.Recommended where operating pump pressure arebelow 40 PSI and GPM velocities less than 5’ per/sec
Flanged Series 37 Well & Pipeline service airvalves are supplied with Arrestor Check Valves,function to stop the flow of water, (For a fractionof a second) entering the upper chamber of theair valve. The Arrestor Check then opens instant-ly, water enters the air valve, all air is exhaustedand the air valve shuts. This Arrestor Checkaction allows for a slow non shock air valve shut-off. To prevent pump or pipeline damage theshut-off/open action of the arrestor check occurspractically instantaneously. It is self regulatingand requires no adjustment in the field. ArrestorCheck air valves are recommended at highpoints where velocities exceed 10’ / second in themain line.

VACUUM PREVENTION AND SLOW AIR RELEASE FORPRESSURE SURGE CONTROL
Cla-Val Vacuum Breakers are reliable and economical pipeline surgecontrol components, requiring no regular maintenance.
The Vacuum Breaker Valve (Large orifice combined with Air ReleaseValve (small orifice) are normally closed. But when installed at pointswhere water column separation can occur, both orifices open admittingair into pipeline, then instantly close to trap air and thereby cushioningrejoining of the water column. In this manner severe pressure surge/waterhammer is prevented as the system returns to normal operation.
Simultaneously the small orifice Air Release Valve opened...due to vac-uum and stays open...venting the discharge of trapped air from pipelineslowly until gradual normal pipeline pressure is achieved. Various smallorifice are available. See small orifice chart, Page 45.
Water column separation in a pipeline may create high levels of vacuumonly momentarily, but the severe damage,such as a pipeline rupture canoccur when the water column rejoins. Also momentarily vacuum condi-tions can easily cause a thin wall pipeline or sealed water tank to col-lapse due to vacuum when draining fluid. Metal to Buna-N® insures “droptight” seal at any pressure. For these reasons it is sound engineeringpractice to use Cla-Val Vacuum Breaker Air Release Valves to preventwater column separation in pipelines and collapse of tanks.

The Cla-Val series 34WW Air Release Valve is speciallydesigned for sewage service. It will protect pipelines fromentrained air or gases that collect at high points in sewagepipelines. This valve effectively eliminates air from a system byreleasing small amounts of air before large air pockets canoccur. In extreme cases, the continued accumulation of air with-out release valves can actually stop flow completely. Increasedpower consumption and associated power costs can beanticipated if systems are not properly designed to releaseaccumulated air.
During normal operation, air and gas accumulation will displacethe liquid within the valve and lower the liquid level in relation tothe float. When the level of the liquid lowers to where the float isno longer buoyant, the float will lower and using a mechanicallever will open the valve seat to permit the accumulated air to beexhausted to atmosphere. As air is released, liquid level in thevalve raises the float and closes the valve seat. This cycle isautomatically repeated as often as necessary.
Installation
Series 34WW Air Release Valves are typically installed at highpoints in pipelines and at regular intervals of approximately 1/2mile, along horizontal pipelines.
Mount the unit in the vertical position on top of the pipeline withan isolation valve installed below each valve in the eventservicing is required. A vault with adequate venting and drainageshould also be provided.
For regular cleaning to keep sewage equipment in good workingcondition use the optional customer installed BWKT BackwashKit with back flushing hose and quick disconnect couplings.
Purchase SpecificationsThe air release valve shall be of the float operated, compoundlever design, and capable of automatically releasing accumulatedair, gas or vapor from a pressurized fluid system while it is inoperation.
An adjustable featured orifice shall be used to seal the valvedischarge port with drip-tight shut-off. The orifice diametermust be sized for use within a given operating pressure rangeto insure maximum discharge capacity.

The Cla-Val Series 35WW Air and Vacuum Valve is designed toperform two separate functions in a sewage or wastewater system.First, it will allow large quantities of air to be exhausted from thepipeline as it is being filled. When this air has been ventedcompletely, liquid will enter the valve causing the float to seal tightlyagainst the seat. Secondly, if the line is being drained, the valveresponds to the loss in pressure and opens. This allows air tore-enter the pipeline and prevents potentially damaging vacuumfrom developing.
Note: The Series 35WW does not open under pressure to exhaustsmall quantities of air which may collect at high points duringsystem normal operation. Model 34WW Air Release Valve isrequired for this function. For both functions, select Model 36WWCombination Air Release and Vacuum Valve.

Sizing GuideWhen selecting valve size, consideration should be given to requirements for airrelease due to filling conditions and for air inlet due to draining conditions.1. Determine system fill rate. If fill rate can be controlled to a flow rate less than
actual system design flow during initial fill or refilling, then this rate can be used for selection from the Step One Table.
2. Determine pipeline potential collapsing factor when draining.A. Calculate rate of flow (using Hazen-Williams or similar formulas) for each
high point using the more severe gradient there.B. Determine collapsing pressure (psi) of pipe being used by consulting
manufacturer's literature. Use a safety factor of 4 to 1.C. Using collapsing pressure and high point rate of flow, select valve size from
Step Two Chart which meets or exceeds flow (SCFS).3. Use the larger valve size selected from Step One Table or Step Two Chart.

InstallationThe Series 36WW Combination Air Valve should be installedat high points and grade changes within the pipeline.
Mount the unit in the vertical position on top of the pipeline withan isolation valve installed below each valve in the event servicingis required. A vault with adequate venting and drainage shouldalso be provided.
For regular cleaning to keep sewage equipment in good workingcondition use the optional customer installed BWKT BackwashKit with back flushing hose and quick disconnect couplings.
Purchase SpecificationThe combination air valve shall combine the operatingfeatures of both an air and vacuum valve and an air releasevalve in one housing. The air and vacuum valve portion shallautomatically exhaust large quantities of air during the fillingof the pipeline and automatically allow air to reenter thepipeline when the internal pressure of the pipeline approachesa negative value due to column separation, draining of thepipeline, or other emergency. The air release valve portionshall automatically release small amounts of air from thepipeline while it is under pressure.
The inlet and outlet of the valve shall have the same cross-section area. The float shall be guided by a stainless steelguide shaft and seat drip-tight against a synthetic rubberseal.
The float shall be of all stainless steel construction andcapable of withstanding maximum system surge pressurewithout failure. The body and cover shall be concentricallylocated and of cast iron and the valve internal parts shall beof stainless steel with Buna-N® rubber seat.
The Combination Air Release and Vacuum Valve shall beModel 36WW from Cla-Val., Newport Beach, CA, U.S.A.

Sizing GuideWhen selecting valve size, consideration should be given to requirements for airrelease due to filling conditions and for air inlet due to draining conditions.1. Determine system fill rate. If fill rate can be controlled to a flow rate less than
actual system design flow during initial fill or refilling, then this rate can be used for selection from the Step One Table.
2. Determine pipeline potential collapsing factor when draining.A. Calculate rate of flow (using Hazen-Williams or similar formulas) for each
high point using the more severe gradient there.B. Determine collapsing pressure (psi) of pipe being used by consulting
manufacturer's literature. Use a safety factor of 4 to 1.C. Using collapsing pressure and high point rate of flow, select valve size from
Step Two Chart which meets or exceeds flow (SCFS).3. Use the larger valve size selected from Step One Table or Step Two Chart.

Series PV30 Split Body Pinch Valves
OPERATION The Cla-Val Series PV30 Pinch Valves provide a positive means to controlflow of hard to handle, aggressive media such as slurries, sludges and drysolids.The standard, pure gum elastomer sleeve, the only moving part ofthe valve, is contained in a cast iron or aluminum housing. The annularspace surrounding the sleeve and the housing becomes the valve actuatorwhen charged with air or water.As pressurized air or water enters the annular space, the elastomer sleeveis squeezed shut. Venting the pressurized air or water opens the valve.
MAINTENANCECla-Val Split Body Pinch Valve is truly maintenance free because it has nomechanical moving parts. The only wetted part is the elastomer sleeve,made of reinforced polyester fabric for longer lasting cycle life. The sleeveis the only part needed for future replacement.

PRINCIPLES OF OPERATION
Valve is in open and normal flow of heavy slur-ries or dry powder materials is maintained.
Valve closes when compressed air is intro-duced into valve forcing the flexible sleeve totighten, stopping flow.
Flow is resumed when air pressure isreleased. Packed material can be loosenedby pulsing the air supply which creates athrottling or flexing action of the sleeve.

Often, in slurry or dry powder systems, process is interrupted bygate, globe, plug or butterfly valves that have been cloggedwith material. There is a solution, Mini-Pinch Valves.
Designed for easy installation. Mini-Pinch Valves can be used toeffectively control viscous or abrasive material flow. The ruggeddesign delivers consistent and long life.
In operation, flow passes smoothly through the full port elas-tomer sleeve. To close the valve, plant or instrument air is intro-duced into the valve body.The increased pressure collapses thesleeve and stops the flow, even against trapped solids.To reopenthe valve, the compressed air is vented and regular flow isrestored. By changing the air pressure, flow rate can be controlled.Pulsing the air flow to the valve body can loosen packed material.The Cla-Val MPV valve features machined steel body and end fit-tings with corrosion resistant electroplate finish.

• Full port design• Accurate pressure instrument protection• One wetted part• Operates multiple instruments
The Cla-Val CVPS Pressure Sensors provide the ideal method ofprotecting pressure measurement and control instruments inprocess lines. The full port flow through design of CVPS sensorsis self cleaning, eliminating the problem of seal cavity blockagethat is common with diaphragm type pressure sensors. Theinstrumentation is completely isolated from the process fluid line.
The CVPS wafer style pressure sensors contain only one wettedpart, with integral flange gaskets provided by the one piece moldedsleeve, and are available to suit all ANSI flange classifications. Avariety of sleeve materials is available to provide optimum abra-sion and corrosion resistance for different process fluids. T.P.S.style pressure sensors are available with alloy metal and plasticthreaded ends for small diameter piping systems.
Changes in the pipeline or vessel pressure are transmittedthrough the elastomer sleeve to the sensing fluid which operatesthe pressure instrument mechanism. The CVPS pressure sensorprovides numerous advantages over commonly used diaphragmtype sensors.
The large sensing area results in consistently accurate pressurereadings, even with normally hard to gauge process fluids.Because of the high volume of sensing fluid available for dis-placement, compared to conventional diaphragm seals, multipleinstrument arrangements are possible and a variety of pressureinstruments can be used.
The CVPS pressure sensors can be used to protect gauges, sen-sors, transducers, and transmitters in a variety of pressure meas-urement and control applications.

The 71 Series valves provide drip-tight closure forstorage tank block valves operating in conjunction with pumps deliveringproduct from the tank.
The valves operate to control initial flow and shut-off flow into the receiv-ing tank using electric signals from product meters or central computerdelivery systems. The valves also provide positive valve shut-off for prod-uct delivery and lockout the system until all components are ready forproduct loading. When flow is initiated the meter signals the 71 Seriesvalve to open slowly until full flow is established. Just before flow is to beterminated the meter signals the valve to slowly close preventing surgesfor smooth flow to final top-off. Precise product delivery is assured withdrip-tight shut-off every time.
Various control functions can be combined with the basic single-stageloading operation for more complete control of product flow during tankloading operations. Available control functions include delivery pressurereduction, flow control, pressure sustaining control, remote deadmanshut-off, electrical or manual lockout, excess flow shut-off, surge shutdown, electrical or hydraulic selection between two delivery pressuresand check feature.
Used In conjunction with a customer-sup-plied product-loading system (for example -Cla-Val Pantograph) and meter, Cla-Val 71Series Single-Stage Loading Valves offer thesafest and most accurate product loading atthe highest flow rates with minimal head loss.Product delivery can be initiated by centralcomputer signals or by operators at the load-ing station.

Excess Flow Valve
138
85-01685-01
The Cla-Val Model 85-01/685-01 Excess Flow Valve is a pilot-operatedvalve which closes when the flow rate exceeds the setting of the control.The pilot control is a snap action device which is cocked in "normal flow"position. An increase in the flow to the "excess flow" condition causes thecontrol to be released which in turn applies operating pressure to the mainvalve in such a way to close it immediately. A manual re-set button is pro-vided to make it impossible to resume operating until the operatordepresses the re-set button.
The flow rate at which the valve closes can be adjusted by varying thecompression on the pilot control spring. The range of adjustment varieswith the size of the orifice. When specifying this valve give the followinginformation:
I. Desired shutoff flow rate in gpm
2. Range of adjustment required in gpm
3. Liquid being handled
Flow losses can be reduced to a minimum by specifying as small anadjustment range as possible. In no case should this range exceed a fourto one ratio between minimum and maximum.

Commercial Refueling Nozzle
342GFMODEL
The Cla-Val Model 342GF Nozzle is apressure fueling nozzle that sets thecommercial aviation standard for safer,stronger, and faster refueling nozzles. Itconnects to a single point receptaclemounted under the wing or on the fuse-lage of an aircraft or is used as a bottom-loading connection on refueling vehicles.The nozzle is constructed of aluminumand stainless steel.To ensure maximum safety during refuel-ing, the Cla-Val 342GF Nozzle has pri-mary and secondary interlock systems.The primary interlock ensures that thenozzle cannot be opened when it is notconnected to an aircraft adapter. The sec-
ondary interlock protects the nozzle fromthe hazards of interfacing with badly wornaircraft adapters. Even when used with abadly worn adapter, the nozzle is safer,because it uses square register pins thatprovide positive alignment with thesquare slots in the adapter. In addition,the Cla-Val 342GF Nozzle cannot beremoved from the adapter until the oper-ating lever is rotated to the fully closedposition.To achieve maximum strength and dura-bility, the Cla-Val 342GF Nozzle uses astainless steel bayonet ring cast withinthe aluminum collar of the nozzle. Thecrank shaft of the nozzle extends across
the entire width of the interior flow pathand is supported from end to end by astructural wall that splits the flow path.This wall supports the crank shaft whilestraightening the flow and keeping flowresistance as low as possible. The inletquick disconnect includes a swivel fea-ture that allows the nozzle to swivel onthe delivery hose or pantograph, resultingin easier connections.To reduce aircraft refueling times, the flowresistance through the Cla-Val 342GFNozzle has been reduced to the lowestpossible level. The Cla-Val 342GF Nozzlehas the lowest head loss, which means itcan fill an aircraft faster than any othernozzle.

Flow
The Cla-Val Model X69H Venturi is anadjustable flow compensating device,which precisely emulates the deliverypressure at the nozzle, regardless ofchange in the flow rate. Typically, theventuri is mounted just downstream ofthe pit valve allowing the pit valve tosense locally a pressure that matchesthe nozzle delivery pressure. As theflow rate increases the sensed pres-sure decreases. The control valvesenses the decreased pressure and
automat ical ly compensates forthe system pressure loss. Flowcompensat ion is f ie ld adjustedto precisely match the pressureloss of the system.Two separate outputs are standard onthe Cla-Val X69H Venturi. These out-puts can be independently adjusted tosimulate the nozzle delivery pressurefor two different fuel flow paths. Forease of adjustment, the output adjust-ing screws are conveniently located
side by side on top of the venturi. Thenameplate includes easy to followadjustment instructions.The venturi body is anodized alu-minum. All valve components arestainless steel with Nitrile seals. Allpassages are machined into the body.That means there are no externaltubes or fittings to be damaged. TheCla-Val X69H Venturi is available ineither 3” or 4” diameters.
