Unpacking

1. While unpacking the valve, check thepacking list against materials received.Lists describing valve and accessories arein each shipping container.

2. When lifting the valve from shippingcontainer, position the lifting straps throughthe yoke legs to avoid damage to the tubingand mounted accessories.

WARNING: When lifting anactuator with lifting strapsthrough the yoke legs, be awarethat the center of gravity maybe above the lifting point.Therefore, support must begiven to prevent the actuatorfrom rotating.

3. Contact your shipper immediately if there isshipping damage.

4. Should any problem arise, call yourrepresentative.

INSTALLATION1. Before installing the valve, inspect it, and

other associated equipment, for anydamage and any foreign material.

2. Be sure that the body interior is clean, thatpipelines are free of foreign materials, andthat the valve is oriented in such a way thatpipeline flow is in the same direction as thearrow on the side of the valve.

3. The assembly of the control valve may beinstalled in any orientation unless otherwiselimited. However, whenever possible, thevalve should be installed with the actuatorvertical above the body. This is alsoimportant for cryogenic applications to keepthe packing isolated from the flowingmedium, permitting the packingtemperature to remain close to ambienttemperature.

CAUTION: Do not insulateextension bonnets that areprovided for hot or coldservices.

4. Be sure to allow sufficient overheadclearance to provide for disassembly of theplug from the valve body. Refer to Table 2 below for overhead clearancerequirements.

Table 2: Overhead ClearanceRequirements

5. If welding the valve into the line, useaccepted piping and welding practices. Inthe case that the valve has separable endflanges, the half rings must be installed onthe body before bolting the valve into theline in order to insure a tight connection.

WARNING: Failure to install halfrings on the valve body couldresult in serious injury.

Note: Depending on valve body materialsused, post weld heat-treating may berequired. This may cause damage to internalelastometric and plastic parts. Shrunk-fitpieces and threaded connections may alsoloosen. In general, if post weld heat-treatingis to be performed, all trim parts should beremoved. Contact your Optimux sales officefor additional information.

6. Connect air supply and instrument signal(air or mA) lines. Throttling control valvesare equipped with a valve positioner. Twoconnections are marked: One for the airsupply and the other for the instrumentsignal. Both the actuator and positioner aresuitable for 150 psi/10.3 Bar air supply. Anair regulator is not required unless thesupply pressure exceeds 150 psi/10.3 Bar.The air filter should be installed before thepositioner unless the supply air is unusuallyclean and dry.

CAUTION: On valves equippedwith air filters, the filter must point down for properperformance.

Note: In some unusual cases, air supply mustbe limited to less than the previouslymentioned amount of 150psi/10.3 Bar. In thiscase, a sticker found near the upper air porton the actuator cylinder will indicate this andan air regulator should be installed to insurethat the supply pressure does not exceed theline pressure indicated on the sticker.

MAINTENANCEValve parts are subject to normal wear andmust be inspected and replaced as necessary.

Inspection and maintenance frequencydepends on the severity of service conditions.This section contains preventive maintenancesteps which can be performed while the valveis still in-line and, in some cases, still inservice. If a problem is suspected of beinginternal, refer to the Assembly/Disassemblysection.

1. Inspect end flanges and bonnet for signs ofgasket leakage. Tighten flange and bonnetbolting (if required). See Table 4

2. Check the pressure-balance sleeve, metalbellows seal, body drain plug, etc. (ifincluded) for fluid leakage to theatmosphere.

3. Keep valve clean and repaint areasaffected by severe oxidation

4. Examine the valve for damage caused bycorrosive fumes or process drippings.

5. Check lubricant supply and add lubricant ifnecessary. See Table 3 for commonlubricants.

6. Packing box bolting must be slightly overfinger-tight. Tighten only as necessary toprevent stem leakage.

CAUTION: Do not over-tightenpacking. This may causeexcessive packing wear andhigh stem friction, which can

impede stem movement.

7. Be sure that all accessories, brackets, andbolts are securely fastened.

8. Check rubber bellows for wear.

9. Remove any foreign substances from theplug system.

10. Spray a soap solution around the cylinderactuator that retains the ring, adjust screwand actuator stem guide for air leaksthrough the O-rings.

11. If possible, remove air supply and observeactuator for correct fail-safe action.

12. If the valve contains an air filter, check andreplace cartridge if necessary.

13. Be certain that stem clamp and positionerlinkage are securely fastened. If the stemclamp is loose, check the plug threadengagement. (For the correct procedureon aligning the plug with the seat, refer tothe "Reassembly of the Actuator" section ofthis manual).

14. Stroke the valve, if possible, and check forsmooth, full stroke operation. Wobbly stemmovement could be a sign of an internalvalve problem.

Note: Erratic stem movement is commonwhenever Grafoil packing is utilized.

WARNING: Keep hands, hair,clothing, etc. away from allmoving parts when operatingthe valve.

ASSEMBLY AND DISASSEMBLYBody Disassembly

In disassembling the valve body, refer to Figure4 and continue as follows:

WARNING: Depressurize line toatmospheric pressure anddrain all fluids beforecommencing work on the valve.

1. If valve is air-to-close, skip to step 2. Ifvalve is air-to-open, apply air under pistonto raise the plug off the seat before takingthe valve apart.

2. Take out the bonnet flange bolting whichwill allow for removal of the actuator,bonnet, and plug from the valve.

CAUTION: Heavy actuators mayrequire a hoist. A lifting ring isprovided on most valves forthis function; otherwise, lift thevalve with the yoke legs using alifting strap and a hoist. Careshould be taken to lift theactuator and plug straight outof the body to avoid damage tothe seat as well as to the plug.

3. Lift retainer, seat ring, and gaskets from thebody.

4. See to it that the seating surfaces on boththe seat ring and plug are free of damageso that a tight shutoff is ensured. Be surethat gasket surfaces on the seat ring,bonnet, and body are clean andundamaged.

5. To inspect the plug, remove by looseningthe stem clamp and gland flange, also, takeoff the yoke clamps.

Note: With air-to-close, fail-open valves, itmay be necessary to apply a small amount ofair to the top of the actuator to move the plugaway from the bonnet. If not, some irritationmay occur to the plug.

Turn the actuator off the plug and bonnetwithout allowing the plug to rotate inside thebonnet. Remove the plug carefully through thepacking box.

6. If re-machining is necessary on the seatsurfaces, both surfaces on plug and seatmust be reworked. The seat angle on theplug is 30 degrees; the seat ring is 33degrees. Lapping will not be necessary ifproper assembly procedures are followed.


5

CAUTION: In the case that re-machining is necessary, besure to protect the stem duringturning. Insure concentricity ofthe seat surface with the plugstem (or outside diameter of theseat ring, if machining theseat).

7. To replace packing or change the packingbox configuration, push out the packing,spacer, and guides with a dowel of a similarsize as the plug stem.

WARNING: For valves equippedwith separable end flanges, donot machine the body gasketsurfaces. Machining couldcause gasket leakage andfailure of the valve.

8. In the case that separable end flangesneed to be removed, file off tack welds orpull rivets behind the flanges.

CAUTION: If separable endflanges and spiral woundgaskets are used, use gasketswith outer back-up rings.Failure to do so could result inexcess stress in someapplications.

Note: To prevent flanges from dropping offduring shipping, a tack weld or stainlesssteel rivet has been installed behind the endflanges.

Body Reassembly

To reassemble the valve body, refer to Figure4, and continue as follows:

1. In the case that packing was removed, referto Figure 2 and install new packing exactly

as shown. Be sure to leave at least 1/8-inchat the top of the packing box for the topguide to enter. Different spacer lengthsallow a wide variety of packingconfigurations, such as twin seal andvacuum pressure packing.

WARNING: Valves with extendedbonnets or metal bellows sealsmust not have lower packinginstalled. Rather, lower packingrings should be installed withthe upper set.

Wherever graphite guides are used, thegraphite liners should be replaced eachtime the valve packing is replaced. Underno circumstance, should the valve bereplaced without graphite liners and guides.

2. Insert the plug stem into the packing box,being sure not to scratch the stem orguides.

3. Turn actuator back onto the plug, withoutturning the plug inside the bonnet. Becertain that the gland flange and bonnetflange are in place prior to engaging theplug stem and actuator stem threads.

Note: To prevent galling, do not let the glandflange come into contact with the polishedplug stem.

Leave about three to four plug stemthreads exposed. Attach yoke clamp andgland flange bolting. When working withvalves using a 2-inch spud, make sure thatthe half rings are in place between the yokeand bonnet. Tighten yoke clamp boltingfirmly.

4. Install new seat gaskets as well as a newbonnet beveled edge up for Teflon gaskets.

5. Introduce the seat ring into the body withthe step side down. Place the seat retainerinto the body with the thin end of thecathedral window down.


6

Note: For ANSI Class 900 and above valves,valve sizes up through 1.5-inch, the seatretainer window should be placed in the bodywith the window facing toward the valveports. For valves 2-inches or greater in size,the bar of the retainer should face toward thevalve ports.

6. For air-to-open valves, place air under theactuator piston to retract the plug.

7. Let down the plug and body squarely intothe body. Take caution as not to scratch theplug as it enters the body.

8. To properly align the seat ring and plug, firstbring the bonnet bolting to finger tightness.

a. If the actuator is pneumatic, apply airpressure above the piston to seat theplug in the seat ring, then skip to step 9.

b. If the actuator is electric or hydraulic,move the actuator stem down until it isfully extended. Then retract the actuatorstem 1/8-inch/3.175-mm. Mount thestem clamp onto the plug stem/actuatorlimit switches according to the operatingmanual of the actuator.

Note: The following step (9) pertains only tovalves with pneumatic actuators. In the casethat an electric or hydraulic actuator is used,return the plug to the mid stroke position andproceed to tighten.

CAUTION: For electric orhydraulic actuators, failure toreturn the plug to a mid strokeposition will cause damage tothe actuator and/or the valvewhile the bonnet is beingtightened.

9. If the valve is air-to-close, skip this step andcontinue to step 10. Check for proper plugseating in air-to-open valves as follows: Ifproper seating occurs, the bonnet flangewill be forced up against the finger tightbody with such force that it will not be

possible to wriggle the flange. If improperseating occurred, the bonnet flange can bewriggled with light hand force. If thisoccurs, place air under the actuator pistonand retract the actuator to approximatemid-stroke position. Turn the plug out ofthe actuator stem one additional thread andrepeat the seating procedure describedabove. When the bonnet flange becomestight against the finger tight body bolting,the plug is then properly seated.

10. For pneumatic actuators, put the plug inthe closed position. For electric, hydraulic,or mechanical actuators, move the plug tothe mid-stroke position. Tighten the bonnetflange bolting in such a way that willmaintain the bonnet flange square (orparallel) with the body. Tighten the first bolt1/6 of a turn, then,tighten the bolt directlyopposite 1/6 of a turn and so on around theflange. Tighten all the bolts firmly andevenly to compress the bonnet gasket andseat the bonnet. Torque the bonnet bolts tothe suggested torque values in Table 4.

Table 4: Suggested Bonnet Bolting TorqueValues (ft. lbs. /Nm, ± 10%)

11. To seat the plug, apply air over the piston.For throttling valves, adjust the stem clampso that, with full instrument signal to thepositioner, the full signal scribe line on thepositioner cam points to the center of thecam roller bearing.

Note: Concerning on/off valves, the bottomof the stem clamp should be lined up with thebottom of the actuator stem (± 1/16-inch/1.60mm).

Make the stem clamp bolting tight. Propertightness is important since this adjustmentfastens the actuator stem to the plug stem.Adjust the stroke plate so that the stemclamp points to the "closed" position.

12. Lastly, if the valve was taken out of the line,when reinstalling, be sure that the flowarrow shows correct flow direction.

Actuator Disassembly

When dealing with air-to-open valves, theactuator may be disassembled while still on thevalve. In the case of air-to-close valves, theactuator must be removed from the valvebefore it is disassembled. Refer to Figure 5 todisassemble the actuator. Proceed as follows:

Note: Steps 1-4 pertain to the removal of theactuator from the valve. If the actuator is tobe disassembled while still on the valve, skipto step 5.

1. Be certain that the plug is not seated on theseat ring as well as not back-seated againstthe bonnet. To insure this, attach an air hoseto the appropriate side of the cylinder andrelease pressure on the opposite side.

CAUTION: Critical surfaces maybe galled if the plug is notpositioned correctly betweenthe bonnet and seat ring.

2. Loosen the stem clamp.

3. Take out the packing box bolting and yokeclamps.

4. Completely unscrew the actuator off of theplug and bonnet without rotating the pluginside the bonnet.

CAUTION: Do not allow the plugto drop and collide against theseat after turning the actuatoroff of the plug threads.

5. Disconnect tubing.

6. Alleviate the spring compression by takingout the adjusting screw.

CAUTION: Do not put ascrewdriver through the liftingring to take out the adjustingscrew; doing so may causedamage to the weld betweenthe lifting ring and the adjustingscrew.

WARNING: Spring compressionMUST be relieved beforecontinuing with disassembly.

7. Use two screwdrivers to remove theretaining ring from the groove. Insert themin the ring’s slot and pry it from the groove.

8. For air-to-open configurations, pull thecylinder off of the yoke and piston. Removespring for cleaning and inspection.

WARNING: Do not use airpressure to remove thecylinder.

For air-to-close configurations, removepiston-retaining nut and slide piston off ofthe actuator stem. The spring can then beremoved.

9. Inspect the actuator stem O-ring byproceeding as follows: remove the stemclamp and bellows, and push the actuatorstem through the yoke being careful not togall the stem. The O-ring can then beremoved and replaced.


8

Note: The actuator stem bushings arepressed into the yoke; it is not necessary toremove the bushing in order to replace the O-ring.

Actuator Reassembly

For actuator reassembly, refer to Figure 5.Continue as follows:

1. All O-rings should be replaced and the newones should be lubricated. Most O-ringscan be lubricated with a silicone lubricant.(Do not use a silicone lubricant on siliconeO-rings)

2. Be certain to clean and lubricate all internalparts before beginning reassembly.

3. In the case that the actuator stem has beenremoved, replace the piston stem O-ring,and reassemble the piston and actuatorspacer on the actuator stem according tothe valve’s air-action. If air-to-close, thespring button has to be inserted under theactuator stem-retaining nut. Tighten theretaining nut firmly.

4. For air-to-close configurations, place thespring under the piston and insert theactuator stem through the yoke – be carefulnot to gall the stem or bushings. Be surethat the spring is retained in the groove ontop of the yoke. For air-to-openconfigurations, insert the actuator stemthrough the yoke and place the spring andspring button above the piston.

5. Mount the cylinder and make certain thatthe yoke is pushed deep enough into thecylinder for the retaining ring to be installed.

6. Reintroduce the retaining ring by pushing itinto the groove a section at a time until it isin place. Replace the stem bellows and thestem clamp.

7. Reinstall the gasket and adjusting screwusing a new adjusting screw gasket. Theadjusting screw should be tightened only tothe point where it creates an air seal withthe gasket.

Note: For air-to-open configurations, be surethat the hole in the spring button is directlycentered under the adjusting screw.

CAUTION: Do not put ascrewdriver through the liftingring to reinstall the adjustingscrew; doing so may damagethe weld between the lifting ringand adjusting screw.

8. Apply air over the piston and place theactuator subassembly, making certain thatthe gland and bonnet flanges are in place,onto the valve. If the valve has a 2-inchspud, make sure that the half rings are inplace between the yoke and bonnet.Connect the plug stem and actuator stemthreads. Cautiously turn the actuatorclockwise until the plug stem is engaged 3to 4 turns.

CAUTION: Do not allow the plugto turn on the seat to avoidpossible stem and/or seatgalling.

9. For air-to-open valves, apply air under thepiston, for air-to-close valves, apply air overthe piston, do either in order to prevent theplug head from touching either the seat orthe bonnet. Continue turning the plug steminto the actuator stem until 2 to 3 plug stemthreads remain exposed.

CAUTION: To prevent galling ofthe polished plug system, donot allow the gland flange tomake contact with the polishedplug system.

CAUTION: Do not allow the plugto turn on the seat so as toprevent possible stem and/orseat galling.


9

10. Apply air over the piston to drive the plugand lift the yoke off of the bonnet. Theyoke will lift approximately 1/16-inch(1.60mm). If the space is not that size,apply air under the piston to retract theactuator stem and screw the plug in or outas needed. Repeat until the 1/16-inch(1.60mm) space is created.

11. To attach the yoke clamps and packing boxbolting, apply air under the piston. Tightenthe yoke clamp bolting firmly. The packingbox nuts should be just over finger-tight.

CAUTION: Do not over-tightenpacking.

12. To seat the plug, apply air over the piston.For all throttling valves, adjust the stemclamp so that, with full instrument signal tothe positioner, the full signal scribe line onthe positioner cam points to the center ofthe cam roller bearing.

Note: For on/off valves, the bottom of thestem clamp should line up with the bottom ofthe actuator stem (±1/16-inch).

Tighten the stem clamp bolting to securethe actuator stem to the plug stem. Adjustthe stroke plate so that the stem clamppoints to the "closed" position.

13. Reconnect the actuator/positioner tubing,supply, and signal lines.

AIR-ACTION REVERSALAir-to-Open

To switch the air-action from air-to-close to air-to-open continue as follows:

1. Adhere to the instructions for disassemblyof the actuator (see "Actuator Disassembly"section).

2. Reassemble the actuator with the spring,actuator stem spacer, and spring buttonover the piston. For proper alignment, thecenter hole in the spring button shouldengage the end of the adjusting screw.

3. The positioner must be changed as well, todo so, refer to the appropriate positionermanual.

Air-to-Close

To switch the air action from air-to-open to air-to-close continue as follows:

1. Adhere to the instructions for disassemblyof the actuator (see "Actuator Disassembly"section).

2. Reassemble the actuator with spring andactuator stem spacer below the piston. Thespring should sit in the spring groove on topof the yoke. The spring button is not usedon air-to-extend configurations and isstored above the piston (the actuator stemretaining nut holds the spring button inplace).

3. The positioner must be changed as well. Todo this, refer to the appropriate positionermanual.
