Consolidated Pilot Operated Safety Relief Valves 3900 (SRV-1/Q2.02)3900.2

3900 Flanged Series Overview

CONSOLIDATED, world leader in providing safety and safety relief valvesolutions, offers the new CONSOLIDATED Modular Pilot Valve (MPV), a pilotoperated safety relief valve. The 39MPV is a unique pilot valve design;combining top performance, capabilities and features within aneconomical, modular assembly. CONSOLIDATED has accomplished this featby successfully designing an optimized safety “system” that offersversatility of application, yet provides cost effective standardization.Proven concepts and principles refined from over 100 years of successfuldesign and application experience have been integrated into theCONSOLIDATED MPV, resulting in the production of a new and highly reliablepilot operated safety relief valve which is easy to operate and maintain.Global concern for the environment continues to expand. The need toimprove the operational efficiency of all types of process plants isworldwide. The need for relief valves that provide bubble tight operationand precise opening and closing pressures is increasing due to this trend.CONSOLIDATED Pilot Operated Safety Relief Valves offer high qualityproduction products, performance characteristics and features that areconsistent with today’s industry demands.The combining of our pilots into one unique design provides majorbenefits. This new design pilot valve is suitable for incompressible andcompressible applications including steam. Adapting to variousapplications will require only the appropriate selection of soft goods andoptions to meet the service conditions.

VersatilityThe CONSOLIDATED MPV is the FIRST true modular pilot operated safety reliefvalve design that combines pop and modulating functions within a singleassembly suitable for incompressible and compressible fluids including steam.

CONSOLIDATED MPV pilot operated safety relief valves meet API 526requirements. For higher capacity requirements, full bore sizes areavailable up to 69.94 sq. inches, some with dual outlets. Availablepressure class ratings are ANSI Class 150 to Class 1500.

Total ServiceThe MPV is manufactured by CONSOLIDATED, a TOTAL solutions provider ofpressure relief products offering unmatched application expertise andafter sales support on a world wide basis.

IntroductionCONSOLIDATED 39MPV Series Pilot Operated Safety Relief Valves aredesigned to provide reliable protection for a broad range of pressurizedsystems applications. The operating characteristics and design of pilotactuated relief valves differ significantly from spring loaded pressure reliefvalves. It is extremely important that the user recognizes the merits ofeach design and select valves based on a valid comparison. TheCONSOLIDATED pressure relief valve designs meet the needs of mostapplications found in the markets we currently serve.CONSOLIDATED strives to provide the best available information, data andassistance to its customers in the selection and application of ourproducts. It is impractical, however, for CONSOLIDATED personnel to betrained in all systems and processes in which our products might be used.Ultimate responsibility remains with the customer as the process owneror designer.

Product types covered in subsequent pages are noted below.

The CONSOLIDATED 3900 series pilot operated safety relief valve is supplied with a non-flowing pilot valve. This single pilot design is suitable for bothincompressible and compressible applications and performs equally well on liquid, vapor or two-phase flow services. The set pressure will not requireadjustment if the service condition changes.

Because of its modular design, the 39PV (pop pilot) can be converted to a 39MV (modulator pilot). This makes the CONSOLIDATED 39PV and 39MV pilotvalve the most versatile pilot valve on the market.

Main Valve Materials

3900 (SRV-1/Q2.02)3900.7

The main valve has six basic components. Assembly and disassembly areaccomplished through top entry. This means that as long as there is nopressure in the system, routine maintenance, such as replacement of O-Rings and seals, may be done with the valve in place, virtuallyeliminating the need for cranes and additional manpower.

BaseThe base is cast with integral flanges. It forms the main structure and is apressure boundary component since it will be exposed to process media.To ensure integrity and reliability, all base castings are produced to thelatest addition to the ASME Boiler & Pressure Vessel Codes. The standardmaterials are Grade WCC carbon steel, and Grade CF8M 316 stainlesssteel. Other materials such as Monel, Hastelloy, and additional code-approved materials are available to satisfy more demandingrequirements. The discharge side of the body is drilled and tapped forpilot venting. If the pilot is vented to the atmosphere, a pipe plug isinstalled to secure this area.

NozzleThe 316 stainless steel nozzle performs two functions: First, it forms thelower sealing surface. Second, the nozzle controls the capacity. The orifice ismachined into the nozzle ensuring that rated flow capacities will be obtainedshould an overpressure condition occur. The nozzle is threaded or bolted intothe body and sealed with an O-Ring. By threading or bolting the nozzle itmay be removed easily for repair or replacement.

GuideThis one piece guide of 316 stainless steel ensures true alignment ofthe disc and nozzle for positive, bubble tight sealing. The heavy guideconstruction is designed to prevent warping or egging when the valveis in service.

DiscThe disc is 316 stainless steel. An O-Ring (part 10) is used for isolatingthe dome chamber when used on air, gas or liquid service. A springenergized Teflon® seal (part 17) is used on the top side of the disc forsteam service. A graphite impregnated Teflon® guide ring (or rings) (part16) provides a low coefficient of friction for the guiding function betweenthe disc and guide. An O-Ring seat (part 12) performs the primary sealingfunction for the disc to ensure bubble tightness. The metal-to-metal stopfor the seat allows the valve to still function, even if the O-Ring isdamaged or destroyed.

Two unique features distinguish the CONSOLIDATED O-Ring seat seal safetyrelief valve from any other design. These are the 50 degree metal-to-metal load bearing seats and the slotted O-Ring retainer.

There are three essentials to a tighter and more secure seal:

1. Concentric AlignmentThe nozzle bore and O-Ring retainer are both machined to anangle of 50 degrees. This ensures that as the valve disc opensand closes the O-Ring is aligned concentrically against the lip ofthe nozzle. Close tolerance between the nozzle and the bodyalso helps to ensure a tight seal when the valve is closed.

2. Maximum Sealing ForceOn the back side of the O-Ring retainer, there are two smallslots. When the valve is closed; process media enters betweenthe machined seat of the nozzle and the O-Ring retainer, andproceeds up the slots behind the O-Ring. This pressure forces theO-Ring against the lip of the nozzle and the curved recess of thedisc. As the pressure within the valve rises to set point, the O-Ring is pressed tightly against the nozzle to maintain maximumsealing force until valve set pressure is reached.

3. O-Ring RetentionWhen the valve opens, the pressure behind the O-Ring escapes fromthese same two slots on the O-Ring retainer. This prevents the O-Ringfrom being ejected. Additionally, the O-Ring encapsulating retainerprevents the O-Ring from being ejected by the high velocity, lowpressure discharge inside the upper valve body.

Cover PlateThe cover plate secures the guide and seals the main body. Each coverplate is drilled and tapped for eye bolts which are used for ease ofassembly or disassembly of the main valve and for handling theassembled valve.

Sensing TubeThe sensing tube is machined from 316 stainless hex bar stock and isthreaded into the main body at a location below the nozzle. The sensingtube picks up media pressure and feeds this pressure through the sensingline to the pilot. To ensure proper orientation, one side of the hex ismarked UP. This marking is to be oriented upward when the valve is sittingon its inlet flange. The pilot valve can also be installed in applicationswhere remote sensing of pressure is used to actuate the pilot. In this case,the sensing tube is installed at the desired sensing location and connectedby the sensing line to the pilot. The sensing tube port in the main valve isthen sealed with a pipe plug.

OtherThe remaining parts: studs, nuts, spring, nameplate, and lead sealcomplete the assembly of the main valve. A wire and lead seal are affixedto the pilot to protect the pilot valve adjustments.

Pop Pilot Product Operation

3900 (SRV-1/Q2.02)3900.11

The CONSOLIDATED MPV™ (Modular Pilot Valve) Pilot Operated Safety Relief Valve is offered as both a non-flowing pop pilot and a non-flowing modulatingpilot within a single assembly. The unique modular design construction allows for an open yoke or vented bonnet and easy field conversion from oneconfiguration to the other. The pilot valve operates by sensing system pressure and using this pressure to control the closing force on the main valvedisc. Increasing inlet valve pressure results in increased closing force until the pilot valve opens. Pressure is relieved at a designated set point as processmedia is allowed to discharge through the main valve. Use of the pop pilot configuration will result in a main valve disc “pop” action from the seatedposition to 100% open. When the overpressure condition is relieved, the main valve disc will reseat due to the increased media pressure directed throughthe pilot valve to the top of the valve disc (dome).

Pilot Tightness: 98% of set pointBlowdown: 2% to 5%, or 2psi (whichever is greater) depending

upon ramp rate.Longer Blowdown Results from:

Pop Pilot Product Operation


Pop Pilot Operation

PV Valve Open (Relieving Position)

Discharge Through Main Valve Return to Normal Position

When the discharging main valve reduces the inlet pressure to the presetblowdown pressure of the pilot, the pilot piston closes the vent seal.Simultaneously, the inlet seal is reopened in the pilot. The main valveinlet pressure is again allowed to enter the dome above the main valvedisc. As the dome pressure equalizes with the inlet pressure, thedownward force created by the differential areas of the disc closes themain valve.

The main valve disc is allowed to lift off the seat as the fluid forceovercomes the now removed pressure load above the main valve disc.The valve discharges to relieve system pressure.

As inlet pressure increases, the pilot piston strokes and seals off themain valve inlet pressure from the dome pressure. The pilotsimultaneously opens the vent seal to relieve the dome pressure toatmospheric pressure.

Domearea

System pressure from the main valve inlet is fed to the dome area bythe pilot through interconnecting tubing. This equalizes the pressure onthe top of the disc with inlet pressure on the seating surface (bottom)of the disc. Since the area of the top of the disc is larger than the areaof the seating surface, the differential area results in a net downwardforce keeping the main valve tightly closed.

Modulating Pilot Product Operation

3900 (SRV-1/Q2.02)3900.15

The CONSOLIDATED MPV (Modular Pilot Valve) Pilot Operated Safety Relief Valve is also offered as a non-flowing modulating pilot design, using a uniquemodular configuration which allows for easy field conversion from pop operation to modulating operation. The modulating pilot operation is very similar tothe pop pilot operation with the added ability to hold a percentage of system pressure above the main valve disc, producing a modulating action. Increasingsystem pressure results in reduced closing force due to venting through the pilot valve. Pressure relief begins at a designated set point as process media isdischarged through the main valve. However, the actual lift of the main valve disc is based on the specific system overpressure condition instead of “popping”instantaneously to the 100% open position as with the pop pilot. This “modulating” action results in improved operating efficiencies through reduced medialoss and lower emissions.

Pilot Tightness: 99% of set point

Blowdown: 1% to 4%, or 2 psi (whichever is greater)depending upon ramp rate.

Pilot Tightness after Pop: 96% of set point

Pilot Tightness after Reseat: 99% of set point

Note: Tightness is defined as zero bubbles per minute.

Modulating Pilot Operation

Domearea

Modulating Position

As inlet pressure increases, the pilot piston strokes and seals off themain valve inlet pressure from the dome pressure. The pilotsimultaneously opens the vent seal to relieve the dome pressure tothe bottom of the modulator piston. The modulator piston has adifferential area with the smaller area being on top. The top of thispiston always sees the main valve inlet pressure. When the domepressure is applied to the bottom of the modulator piston, there is anet upward force. This is due to both pressures being equal (at thispoint), and the lower area is larger than the upper area. Themodulator relieves pressure from the dome to the atmosphere untilforce from the inlet pressure on top of the modulator piston issufficient to move it to the closed position. A certain amount ofpressure remains in the dome. This pressure is controlled by thedifferential area in the modulator. Since the dome pressure has notbeen dropped to atmospheric pressure, the main valve only partiallyopens at the set point. The modulator piston will remain closed untilthe main valve disc is forced into higher lift by increasing inletpressure. As this occurs, the modulator piston may relieve furtherpressure from the dome as necessary to achieve the required maindisc lift within 10% overpressure.

MV Fully Open

As the inlet pressure increases further, the net upward force on the mainvalve increases, allowing the main valve to relieve more pressure. Thedisc obtains full lift (full capacity) within 10% of set pressure.

Return to Normal Position

When the discharging valve reduces the inlet pressure to the pre-setblowdown pressure of the pilot, the pilot piston closes the vent seal.Simultaneously, the inlet seal is reopened in the pilot. The main valveinlet pressure is again allowed to enter the dome above the main valvedisc. As the dome pressure equalizes with the inlet pressure, thedownward force created by the differential areas of the disc closes themain valve.

System pressure from the main valve inlet is fed to the dome area bythe pilot through interconnecting tubing. This equalizes the pressure onthe top of the disc with inlet pressure on the seating surface (bottom)of the disc. Since the area of the top of the disc is larger than the areaof the seating surface, the differential area results in a net downwardforce keeping the main valve tightly closed.

Manual Blowdown ValveAn optional manual blowdown valve is available for relieving the pilotoperated safety relief valve. Consult factory for applications requiring apneumatic or electrical solenoid blowdown valve which may be connectedto a distant location, such as an operator station, for remote actuation.The blowdown valve is ported directly to the main dome area, so that themedia in the dome is vented when the blowdown valve is actuated, thusallowing the main valve to open.For all applications on air, water over 140°F, or steam service, ASMESection VIII - Division 1 requires each pressure relief valve to have a liftingdevice such as a blowdown valve or a means of connecting or applyingpressure to the pilot to verify that the moving parts essential to goodoperation are free to move. (Reference UG 136(a)(3)).The lifting lever or blowdown valve may be omitted under Code Case 2203.All orders for pressure relief valves without levers or blowdown valves forsteam, air and water over 140°F must state specifically that the valves arebeing purchased per Code Case 2203. The purchaser is responsible forobtaining jurisdictional authorization for use of Code Case 2203.

Field Test ConnectionA 1/4” FNPT field test connection is standard on all pilot valve types.This allows the stroking of the valve with an auxiliary media, e.g. air ornitrogen. An internal check valve is present in the field test connectionisolating the inlet media from the test media and at the same time,allowing the valve to open normally in the event of a systemoverpressurization during a field test.

FiltersFilter options are available for dirty applications. These filters are installedin the pilot inlet sensing line.For the 39PV and 39MV, an optional sensing line filter is available. Thisfilter has a 316 stainless steel body, Teflon® seals, and a 40-50 micronstainless steel filter element. This filter is standard for steam service.Other high capacity filter options include: (1) a carbon steel cadmium coated filter body with a 35 micron stainless steelelement, (2) a stainless steel filter body, and (3) an entirely stainless steel filter arrangement. The O-Ring in the filters for steamservice will be Teflon®. These filters may be equipped with a manuallyoperated needle valve which allows for purging the filtered material whilethe valve is in operation.All filter elements are stainless steel, and all filters, including carbon steel, conform to NACE Standard MR0175.A dual filter arrangement is available for applications in which thecustomer is unsure of the filter maintenance requirements. In these cases,a preventive maintenance program may be developed by monitoring thefilters, without taking the valve off line.

Backflow PreventerWhen the pilot operated safety relief valve is not vented directly toatmosphere, it is possible to build up back pressure in the discharge line.This is typical in situations where several valves manifold into a commondischarge header. Should the discharge line pressure exceed the valveinlet pressure, it could cause the piston to lift and allow reverse flowthrough the main valve. This situation can be eliminated through theuse of the Backflow Preventer.

3900 MPV™



Spring CoverAn optional metal spring cover that fits over the yoke arms.

BonnetA vented Bonnet that replaces the Yoke provides protection of personnel. Thebonnet will protect the spring from external debris and weather conditions(See page 3900.14 or 3900.18).

Pressure Differential SwitchElectrical: A pressure differential switch is available which may be wiredto an operator station or some other remote location. The switch willprovide a signal that indicates when the main valve is opening. Thestandard pressure differential switch is a single pole, double throw, rate at5 amps and 30 volts DC with a NEMA 4 enclosure. (For otherconfigurations, consult the factory.)Pneumatic: For applications that do not permit an electrical differentialswitch, an option is available to provide pneumatic signal to indicate whenthe main valve opens.

Remote Pilot MountingThe 39PV and 39MV pilots can be mounted separately from the mainvalve. Remote pilot mounting will allow heating or cooling the pilot in caseambient conditions are outside the scope of the pilot. It will also enablethe user to group several pilots together for control of ambient conditionsin a smaller space. In addition, this promotes easier maintenance.

Dual PilotsA dual pilot arrangement is available for applications in which the pilotvalve O-Rings require monitoring and/or maintenance more often than themain valve. In this installation, the pilot valves may be alternated formaintenance, without bringing the system down.

NOTE: For all option and accessory material variations, contact the factory.

Remote SensingThe pilot valve inlet may be piped to a location remote from the mainvalve. In this application, the customer may pipe the inlet sensing line tosome location other than where the main valve is located and where thepressure will be relieved (for tubing size and maximum length, consultfactory for recommendations.)

Pilot Valve TesterThe pilot valve test indicator is available for the modulating and popaction pilot valves. The valve test indicator measures the set pressure ofthe pilot, while maintaining pressure on the main valve dome area;thereby, allowing only the pilot to actuate. The system shown below isavailable for remote or local testing.

Dirty Service Option

Severe dirty service, precipitation and viscous fluid problems can besolved using the dirty service option offered on the 3900 POSRV. Adirty service option can be added to the standard pilot valve. The kitcontains a 316 SS chamber, an isolation seal and an extended pilotpiston. The module is positioned at the top of the pilot valve body andbelow the pilot valve yoke. Crucial valve components such as themodulator, dome assembly, vent, and inlet seals never come in contactwith the dirty system media. The process media pressure still controlsthe set pressure and blowdown of the POSRV.For applications requiring the main valve to relieve the dirty fluid, analternate clean media supply is piped to the pilot. The alternate cleanmedia must be set at the same pressure as the set pressure of the pilotvalve, but cannot exceed 3750 psig, which is the design limit of the pilotvalve. In the event that the alternate clean media supply is lost, the mainvalve will fail in the open position.For applications requiring the main valve to relieve clean fluid upstreamof the dirty process in order to maintain the dirty process pressure atsafe levels, the dirty process pressure is supplied to the dirty servicemodule. The sensing line from the main valve and the connection tothe main valve dome is connected to the pilot in the normal manner.The pilot is set to operate at the design pressure of the dirty process.When the dirty process pressure reaches the set to open pressure of the

pilot, the pilot is stroked by the increase in the dirty process pressureand the pilot performs the block and bleed operations to effect openingof the main valve. When the dirty process pressure reaches the set toclose pressure of the pilot, the pilot is stroked by the reduction in thedirty process pressure and the pilot performs the block and bleedoperations to effect the closing of the main valve.The dirty service module is a closed chamber. The flow of dirty processmedia to the pilot valve is only that volume required to stroke the pilotin response to increasing dirty process pressure. The limited volume offlowing dirty media entering the pilot makes plugging of the module anunlikely possibility. However, if plugging of the module is a concern, themodule can be filled with a compatible clean liquid and a siphon tubecan be fitted in the connection line between the pilot module and thedirty process.The dirty service option can provide some cost savings in materialselection for corrosive service. It is possible that only the material ofconstruction for the dirty service option will need to be upgraded. Theremaining parts in contact with clean media could use standard materialsof construction.

NOTE: For special material options on the dirty service option consult the factory.

Valve Installation


Valve ConnectionsThe CONSOLIDATED 39MPV Series flanged valves are equipped withANSI B16.5 flanges. For other standards, contact the factory foryour needs.The facing on raised flanges is a spiral finish, 125 to 250 micro inchroughness (Ra).All flange drilling straddles the centerlines of the valve.

Handling and StorageSafety relief valves should be handled carefully. The internal parts of apilot operated safety relief valve are precision machined and fittedtogether to maintain perfect alignment. Rough handling may damage theexternal tubing, pilot, and main valve seats or may cause misalignmentsufficient to incur leakage or erratic operation. Safety relief valves areshipped with a protective covering over the inlet and the outlet. This is toprevent damage to the flanged surfaces and to prevent entry of foreignmaterial into the valve. If the valves are to be stored before installation,the protective covering should be left intact until installation. A clean, drystorage area is recommended. Valves should always be protected with asuitable covering to prevent entry of foreign material.

Inlet PipingPilot operated safety relief valves must be installed in a vertical uprightposition. The inlet piping to the valve should be short and direct from thevessel or equipment being protected. The connection to the vessel shouldbe provided with a radius to permit smooth flow to the valve. Sharpcorners should be avoided. Should this not be practical, then the inletshould be swaged out at least one additional pipe diameter.In any event, the pressure drop from the vessel to the valve should notexceed 3% of set pressure when the valve is flowing full capacity. In noevent should the inlet piping be smaller in diameter than the inletconnection of the valve.

Outlet PipingAlignment of the internal parts of a pilot operated safety relief valve isimportant to ensure proper operation. Although the valve body willwithstand a considerable mechanical load, unsupported discharge pipingshould not impose loads any higher than that stated in the TechnicalInformation section of this catalog, consisting of more than a companionflange, long radius elbow and a short vertical pipe. Care should be takento ensure thermal expansion of piping and supports does not producestrains on the valve. Spring supports are recommended where necessaryto avoid this condition. The discharge piping should be designed to allowfor vessel expansion as well as expansion of the discharge pipe itself. Thisis particularly important on long discharge lines.Consideration should be given to discharge pipe movement resulting fromwind loads. Any oscillation of the discharge piping introduces stressdistortion in the valve body, and the resultant movement of the internalparts may cause leakage.
