DescriptionThese single-port valves have cage guiding,quick-change trim, and balanced

push-down-to-close valve plug action. Valveconfigurations are as follows:

Design ED—Globe-style valve (figure 1) withmetal-to-metal seating for all general applicationsover a wide variety of pressure drops andtemperatures.

Design EAD—Angle version of Design ED, used tofacilitate piping or in applications where aself-draining valve is required.

C-seal trim is available for Design ED valves, Class150, 300, and 600, in sizes 2.5, 3, 4, 6, and 8.C-seal trim is available for Design EAD valves, Class150, 300, and 600, in sizes 3, 4, and 6.

With C-seal trim, a balanced valve can achievehigh-temperature, Class V shutoff. Because theC-seal plug seal is formed from metal (N07718

nickel alloy, Inconel 718) rather than an elastomer, avalve equipped with the C-seal trim can be applied inprocesses with a fluid temperature of up to 593�C(1100�F), provided other material limits are notexceeded.

SpecificationsTypical specifications for these valves are shown intable 1.

Installation

WARNING

Always wear protective gloves,clothing, and eyewear whenperforming any installation operationsto avoid personal injury.

Personal injury or equipment damagecaused by sudden release of pressuremay result if the valve assembly isinstalled where service conditionscould exceed the limits given in table 1or on the appropriate nameplates. Toavoid such injury or damage, provide arelief valve for over-pressureprotection as required by governmentor accepted industry codes and goodengineering practices.

Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

If installing into an existingapplication, also refer to the WARNINGat the beginning of the Maintenancesection in this instruction manual.

CAUTION

When ordered, the valve configurationand construction materials wereselected to meet particular pressure,temperature, pressure drop, andcontrolled fluid conditions.Responsibility for the safety of

process media and compatibility ofvalve materials with process mediarests solely with the purchaser andend-user. Since some body/trimmaterial combinations are limited intheir pressure drop and temperatureranges, do not apply any otherconditions to the valve without firstcontacting your Fisher sales office.

1. Before installing the valve, inspect the valve andassociated equipment for any damage and anyforeign material.

2. Make certain the valve body interior is clean, thatpipelines are free of foreign material, and that thevalve is oriented so that pipeline flow is in the samedirection as the arrow on the side of the valve.

3. The control valve assembly may be installed inany orientation unless limited by seismic criteria.However, the normal method is with the actuatorvertical above the valve. Other positions may resultin uneven valve plug and cage wear, and improperoperation. With some valves, the actuator may alsoneed to be supported when it is not vertical. Formore information, consult your Fisher sales office.

4. Use accepted piping and welding practices wheninstalling the valve in the line. For flanged valves,use a suitable gasket between the valve and pipelineflanges.

Note

Depending on valve body materialsused, post weld heat treating may berequired. If so, damage to internalelastomeric and plastic parts, as wellas internal metal parts is possible.Shrink-fit pieces and threadedconnections may also loosen. Ingeneral, if post weld heat treating is tobe performed, all trim parts should beremoved. Contact your Fisher salesoffice for additional information.

5. With a leak-off bonnet construction, remove thepipe plugs (keys 14 and 16, figure 18) to hook up theleak-off piping. If continuous operation is requiredduring inspection or maintenance, install athree-valve bypass around the control valveassembly.

6. If the actuator and valve are shipped separately,refer to the actuator mounting procedure in theappropriate actuator instruction manual.

WARNING

Personal injury could result frompacking leakage. Valve packing wastightened before shipment; however,the packing might require somereadjustment to meet specific serviceconditions. Check with your processor safety engineer for any additionalmeasures that must be taken toprotect against process media.

Valves with ENVIRO-SEAL live-loaded packing orHIGH-SEAL� live-loaded packing will not requirethis initial re-adjustment. See the Fisher instructionmanuals, ENVIRO-SEAL Packing System forSliding-Stem Valves or HIGH-SEAL Live-LoadedPacking System (as appropriate), for packinginstructions. If you wish to convert your presentpacking arrangement to ENVIRO-SEAL packing,refer to the retrofit kits listed in the Parts Kitsub-section near the end of this manual.

MaintenanceValve parts are subject to normal wear and must beinspected and replaced as necessary. Inspectionand maintenance frequency depends on the severityof service conditions. This section includesinstructions for packing lubrication, packingmaintenance, trim maintenance, and ENVIRO-SEALbellows seal bonnet replacement. All maintenanceoperations may be performed with the valve in theline.

WARNING

Avoid personal injury or propertydamage from sudden release ofprocess pressure or bursting of parts.Before performing any maintenanceoperations:

� Always wear protective gloves,clothing, and eyewear whenperforming any maintenanceoperations to avoid personal injury.

� Disconnect any operating linesproviding air pressure, electric power,or a control signal to the actuator. Besure the actuator cannot suddenlyopen or close the valve.

� Use bypass valves or completelyshut off the process to isolate thevalve from process pressure. Relieveprocess pressure from both sides ofthe valve. Drain the process mediafrom both sides of the valve.

� Vent the pneumatic actuatorloading pressure and relieve anyactuator spring precompression.

� Use lock-out procedures to besure that the above measures stay ineffect while you work on theequipment.

� The valve packing box maycontain process fluids that arepressurized, even when the valve hasbeen removed from the pipeline.Process fluids may spray out underpressure when removing the packinghardware or packing rings, or whenloosening the packing box pipe plug.

� Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.

Note

Whenever a gasket seal is disturbedby removing or shifting gasketedparts, install a new gasket duringreassembly. This ensures a goodgasket seal because the used gasketmay not seal properly.

Packing Lubrication

Note

ENVIRO-SEAL or HIGH-SEAL packingdoes not require lubrication.

If a lubricator or lubricator/isolating valve (figure 2) isprovided for PTFE/composition or other packingsthat require lubrication, it will be installed in place ofthe pipe plug (key 14, figure 18). Use a good qualitysilicon-based lubricant. Do not lubricate packingused in oxygen service or in processes withtemperatures over 260�C (500�F). To operate thelubricator, simply turn the cap screw clockwise toforce the lubricant into the packing box. Thelubricator/isolating valve operates the same wayexcept open the isolating valve before turning thecap screw and then close the isolating valve afterlubrication is completed.

Packing Maintenance

Note

For valves with ENVIRO-SEALpacking, see the Fisher instructionmanual, ENVIRO-SEAL PackingSystem for Sliding-Stem Valves, Form5306, for packing instructions.For valves with HIGH-SEAL packing,see the Fisher instruction manual,HIGH-SEAL Live-Loaded PackingSystem, Form 5263, for packinginstructions.

Key numbers refer to figure 3 for PTFE V-ringpacking and to figure 4 for PTFE/compositionpacking, unless otherwise indicated.

For spring-loaded single PTFE V-ring packing, thespring (key 8, figure 3) maintains a sealing force onthe packing. If leakage is noted around the packingfollower (key 13, figure 3), check to be sure theshoulder on the packing follower is touching thebonnet. If the shoulder is not touching the bonnet,tighten the packing flange nuts (key 5, figure 18)until the shoulder is against the bonnet. If leakagecannot be stopped in this manner, proceed to theReplacing Packing procedure.

If there is undesirable packing leakage with otherthan spring-loaded packing, first try to limit theleakage and establish a stem seal by tightening thepacking flange nuts.

If the packing is relatively new and tight on the stem,and if tightening the packing flange nuts does notstop the leakage, the valve stem may be worn ornicked so that a seal cannot be made. The surfacefinish of a new valve stem is critical for making agood packing seal. If the leakage comes from theoutside diameter of the packing, the leakage may becaused by nicks or scratches around the packingbox wall. If performing any of the followingprocedures, inspect the valve stem and packing boxwall for nicks and scratches.

WARNING

Refer to the WARNING at thebeginning of the Maintenance sectionin this instruction manual.

1. Isolate the control valve from the line pressure,release pressure from both sides of the valve body,

and drain the process media from both sides of thevalve. If using a power actuator, also shut off allpressure lines to the power actuator, and release allpressure from the actuator. Use lock-out proceduresto be sure that the above measures stay in effectwhile you work on the equipment.

2. Disconnect the operating lines from the actuatorand any leak-off piping from the bonnet. Disconnectthe stem connector, then remove the actuator fromthe valve by unscrewing the yoke locknut (key 15,figure 18) or the hex nuts (key 26, figure 18).

3. Loosen the packing flange nuts (key 5, figure 18)so that the packing is not tight on the valve stem.Remove any travel indicator parts and stem locknutsfrom the valve stem threads.

WARNING

To avoid personal injury or propertydamage caused by uncontrolledmovement of the bonnet, loosen thebonnet by following the instructions inthe next step. Do not remove a stuckbonnet by pulling on it with equipmentthat can stretch or store energy in anyother manner. The sudden release ofstored energy can cause uncontrolledmovement of the bonnet.

Note

The following step also providesadditional assurance that the valvebody fluid pressure has been relieved.

CAUTION

Avoid damaging the seating surfacecaused by the valve plug and stemassembly dropping from the bonnet(key 1, figure 18) after being lifted partway out. When lifting the bonnet,temporarily install a valve stemlocknut on the valve stem. Thislocknut will prevent the valve plug and

stem assembly from dropping out ofthe bonnet.

If the cage starts to lift with thebonnet, tap it with a plastic mallet, orother soft material, to be sure it staysin the valve.

4. Hex nuts (key 16, figure 19, 20, or 21) or capscrews (not shown) attach the bonnet (key 1, figure18) to the valve body (key 1, figure 19, 20, or 21).Loosen these nuts or cap screws approximately 3mm (1/8 inch). Then loosen the body-to-bonnetgasketed joint by either rocking the bonnet or pryingbetween the bonnet and valve. Work the prying toolaround the bonnet until the bonnet loosens. If nofluid leaks from the joint, remove the nuts or capscrews completely and carefully lift the bonnet offthe valve.

5. Remove the locknut and separate the valve plugand stem from the bonnet. Set the parts on aprotective surface to prevent damage to gasket orseating surfaces.

6. Remove the bonnet gasket (key 10, figure 19, 20,or 21) and cover the opening in the valve to protectthe gasket surface and prevent foreign material fromgetting into the valve body cavity.

7. Remove the packing flange nuts, packing flange,upper wiper, and packing follower (keys 5, 3, 12, and13, figure 18). Carefully push out all the remainingpacking parts from the valve side of the bonnet usinga rounded rod or other tool that will not scratch thepacking box wall. Clean the packing box and themetal packing parts.

8. Inspect the valve stem threads and packing boxsurfaces for any sharp edges which might cut thepacking. Scratches or burrs could cause packing box

leakage or damage to the new packing. If thesurface condition cannot be improved by lightsanding, replace the damaged parts by following theappropriate steps in the Trim Maintenanceprocedure.

9. Remove the cover protecting the valve bodycavity and install a new bonnet gasket (key 10,figure 19 through 21), making sure the gasketseating surfaces are clean and smooth. Place thevalve plug and stem into the valve body, makingsure it is properly centered on the seat ring. Thenslide the bonnet over the stem and onto the studbolts (key 16, figure 19, 20, or 21) or onto the valvebody cavity if cap screws (not shown) will be usedinstead.

Note

Proper performance of the boltingprocedures in step 10 compresses thespiral wound gasket (key 12, figure 19or 20) or load ring (key 26, figure 21)enough to both load and seal the seatring gasket (key 13, figure 19, 20, or21). It also compresses the outer edgeof the bonnet gasket (key 10, figure 19through 21) enough to seal thebody-to-bonnet joint.

The bolting procedures in step 10include—but are not limitedto—ensuring that bolting threads areclean, and evenly tightening the capscrews, or the nuts onto the studs, in acrisscross pattern. Tightening one cap

screw or nut may loosen an adjacentcap screw or nut. Repeat thecrisscross tightening pattern severaltimes until each cap screw or nut istight and the body-to-bonnet seal ismade. When the operating temperaturehas been reached, perform thetorquing procedure once again.

10. Install bolting, using accepted boltingprocedures during tightening, so that thebody-to-bonnet joint will withstand test pressuresand application service conditions. Use the bolttorques in table 3 as guidelines.

11. Install new packing and the metal packing boxparts according to the appropriate arrangement infigure 3, 4, or 5. Place a smooth-edged pipe over thevalve stem and gently tap each soft packing part intothe packing box.

12. Slide the packing follower, upper wiper, andpacking flange (keys 13, 12, and 3, figure 18) intoposition. Lubricate the packing flange studs (key 4,figure 18) and the faces of the packing flange nuts(key 5, figure 18). Install the packing flange nuts.

13. For spring-loaded PTFE V-ring packing,tighten the packing flange nuts until the shoulder onthe packing follower (key 13, figure 18) contacts thebonnet.

For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown intable 4. Then, loosen the packing flange nuts, andretighten them to the recommended minimum torqueshown in table 4.

For other packing types, tighten the packing flangenuts alternately in small equal increments until one

Trim Maintenance

WARNING

Observe the warning at the start of theMaintenance section.

For C-seal construction, see the appropriate C-sealsections in this instruction manual.

Except where indicated, key numbers in this sectionare referenced in figure 19 for standard 1-through6-inch constructions, figure 20 for Whisper Trim IIIcage detail, figure 21 for the 8-inch Design ED valve,and figures 22 and 23 for WhisperFlo trim. Somevalve plug constructions require three piston rings(key 6).

Disassembly1. Remove the actuator and the bonnet according tosteps 1 through 5 of the Replacing Packingprocedure in the Maintenance section.

WARNING

Avoid personal injury or propertydamage from valve or packing leakage.

The graphite piston rings in a DesignED or EAD valve are brittle and in twopieces. Use care to avoid damage tothe piston rings caused by dropping orrough handling.

Any damage to the gasket sealingsurfaces could cause the valve to leak.The surface finish of the valve stem(key 7) is critical for making a goodpacking seal. The inside surface of thecage or cage/baffle assembly (key 3),or cage retainer (key 31), is critical forsmooth operation of the valve plugand for making a seal with the pistonrings (key 6). The seating surfaces ofthe valve plug (key 2) and seat ring(key 9) are critical for proper shutoff.Protect these parts accordingly whiledisassembling the trim.

2. Remove the packing flange nuts, packing flange,upper wiper, and packing follower (keys 5, 3, 12, and13, figure 18). Carefully push out all the remainingpacking parts from the valve side of the bonnet usinga rounded rod or other tool that will not scratch thepacking box wall. Clean the packing box and themetal packing parts.

3. Inspect the valve stem threads and packing boxsurfaces for any sharp edges which might cut thepacking. Scratches or burrs could cause packing boxleakage or damage to the new packing. If thesurface condition cannot be improved by lightsanding, replace the damaged parts.

4. Remove the load ring (key 26) from an 8-inchDesign ED valve, or the cage adaptor (key 4) fromany restricted-trim valve through 4 inches, and wrapit for protection.

5. On a 6-inch Design ED valve with a Whisper TrimIII cage or WhisperFlo trim, remove the bonnetspacer (key 32) and bonnet gasket (key 10) on topof the spacer. Then on any construction with a cageretainer (key 31), remove the cage retainer and itsassociated gaskets. A Whisper Trim III andWhisperFlo cage retainer has two 0.375-inch-16NPT tappings in which screws or bolts can beinstalled for lifting.

6. Remove the cage or cage/baffle assembly (key 3)and the associated gaskets (keys 10, 11, and 12),and shim (key 51 for the Design ED valve, key 27 forthe Design EAD valve). If the cage is stuck in thevalve, use a rubber mallet to strike the exposedportion of the cage at several points around itscircumference.

7. Remove the seat ring or liner (key 9), seat ringgasket (key 13), and the seat ring adaptor (key 5)and adaptor gasket (key 14) where used in arestricted-trim seat ring construction.

8. Inspect parts for wear or damage which wouldprevent proper operation of the valve. Replace orrepair trim parts according to the following procedurefor Lapping Metal Seats or other valve plugmaintenance procedures as appropriate.

Lapping Metal Seats

CAUTION

To avoid damaging the ENVIRO-SEALbellows seal bonnet assembly, do notattempt to lap the metal seatingsurfaces. The design of the assemblyprevents rotation of the stem and anyforced lapping rotation will damageinternal components of theENVIRO-SEAL Bellows Seal bonnet.

With metal-seat constructions, seating surfaces ofthe valve plug and seat ring or liner (keys 2 and 9,figure 19, 20, or 21) can be lapped for improvedshutoff. (Deep nicks should be machined out ratherthan ground out.) Use a good quality lappingcompound of a mixture of 280 to 600-grit. Applycompound to the bottom of the valve plug.

Assemble the valve to the extent that the cage andthe cage retainer and bonnet spacer (if used) are inplace and the bonnet is bolted to the valve. A simplehandle can be made from a piece of strap ironlocked to the valve plug stem with nuts. Rotate thehandle alternately in each direction to lap the seats.


11

After lapping, remove the bonnet and clean the seatsurfaces. Completely assemble as described in theAssembly portion of the Trim Maintenanceprocedure and test the valve for shutoff. Repeat thelapping procedure if leakage is still excessive.

Valve Plug MaintenanceExcept where indicated, key numbers in this sectionare referenced in figure 19 for standard 1- through6-inch constructions, figure 20 for Whisper Trim IIIdetail, figure 21 for the 8-inch Design ED valve, andfigures 22 and 23 for WhisperFlo trim. Some valveplug constructions require three piston rings (key 6).

CAUTION

To avoid the piston ring (key 6) notsealing properly, be careful not toscratch the surfaces of the ring groovein the valve plug or any of the surfacesof the replacement ring.

1. With the valve plug (key 2) removed according tothe Disassembly portion of the Trim Maintenanceprocedure, proceed as appropriate:

For the carbon-filled PTFE piston ring, The ring issplit in one place. If there is visible damage, spreadthe ring slightly and remove it from the groove in thevalve plug.

To install a carbon-filled PTFE piston ring,Spread the ring apart slightly at the split and install itover the stem and into the groove in the valve plug.The open side must face along the stem, dependingon flow directions, as shown in view A of figure 19.

For the graphite piston ring, The ring can be easilyremoved since it is in two pieces. A new graphitepiston ring is furnished as a complete ring. Use avise with smooth or taped jaws to break thisreplacement ring into halves. Place the new ring inthe vise so that the jaws will compress the ring intoan oval. Slowly compress the ring until it snaps onboth sides. If one side snaps first, do not try to tearor cut the other side. Instead, keep compressing thering until the other side snaps. Be sure to match thebroken ends when installing the ring in the valveplug groove.

CAUTION

Never reuse an old stem or adaptorwith a new valve plug. Using an old

stem or adaptor with a new plugrequires drilling a new pin hole in thestem (or adaptor in case anENVIRO-SEAL bellows seal bonnet isbeing used). This drilling weakens thestem or adaptor and may cause failurein service. However, a used valve plugmay be reused with a new stem oradaptor.

Note

For plain bonnets and style 1extension bonnets, the valve plug (key2), valve stem (key 7), and pin (key 8)are available completely assembled.Refer to the Key 2, 7, and 8 Valve Plugand Stem Assembly tables in the PartsList.

2. To replace the valve stem (key 7), drive out thepin (key 8). Unscrew the valve plug from the stem oradaptor.

3. To replace the adaptor (key 24, figure 18) onENVIRO-SEAL bellows seal bonnets, place the plugstem assembly and valve plug in a soft-jaw chuck orother type of vise so that the jaws grip a portion ofthe valve plug that is not a seating surface. Drive outthe pin (key 36, figure 18). Reverse the plug stemassembly and valve plug in the soft-jaw chuck orvise. Grip the flat areas on the valve stem just belowthe threads for the actuator/stem connection.Unscrew the valve plug/adaptor assembly (key 24,figure 18) from the valve stem assembly (key 20,figure 18).

4. Screw the new stem or adaptor into the valveplug. Tighten to the torque value given in table 5.Refer to table 5 to select the proper drill size. Drillthrough the stem or adaptor, using the hole in thevalve plug as a guide. Remove any chips or burrsand drive in a new pin to lock the assembly.

5. For ENVIRO-SEAL bellows seal bonnets, grip theflats of the stem extending out of the top of thebellows shroud with a soft-jaw chuck or other type ofvise. Screw the valve plug/adaptor assembly ontothe valve stem. Tighten as necessary to align the pinhole in the stem with one of the holes in the adaptor.Secure the adaptor to the stem with a new pin.

AssemblyExcept where indicated, key numbers are referencedin figure 19 for standard 1-through 6-inchconstructions, figure 20 for Whisper Trim III detail,figure 21 for the 8-inch Design ED valve, and figures22 and 23 for WhisperFlo trim.

b. For valve plugs with multiple piston rings:As each piston ring is slid into the cage, makesure the ring is evenly engaged in the entrancechamfer at the top of the cage or cage retainer.Also, make sure to offset the fracture in the ringsto minimize leakage. Carefully press each pistonring into the cage or cage retainer ring.

6. Place the gaskets (keys 12, 11 or 14 if used, and10) and the shim (key 27 or 51) if used on top of thecage or cage retainer. If there is a cage adaptor (key4) or a bonnet spacer (key 32), set it on the cage orcage retainer gaskets and place another flat sheetgasket (key 10) on top of the adaptor or spacer. Ifthere is only a cage retainer, place another flat sheetgasket on the retainer.

7. With an 8-inch Design ED valve, install the loadring (key 26).

8. Mount the bonnet on the valve and completeassembly according to steps 10 through 14 of theReplacing Packing procedure. Be sure to observethe note prior to step 10.

Retrofit: Installing C-seal Trim

Note

Additional actuator thrust is requiredfor a valve with C-seal trim. Wheninstalling C-seal trim in an existingvalve, contact your Fisher sales officefor assistance in determining newactuator thrust requirements.

Assemble the new valve plug/retainer assembly(with C-seal plug seal) using the followinginstructions:

CAUTION

To avoid leakage when the valve isreturned to service, use appropriatemethods and materials to protect allsealing surfaces of the new trim partswhile assembling the individual partsand during installation in the valvebody.

1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also,lubricate the outside diameter of the valve plugwhere the C-seal plug seal must be pressed into theproper sealing position (figure 6).

2. Orient the C-seal plug seal for correct sealingaction based on the process fluid flow directionthrough the valve.

� The open interior of the C-seal plug seal mustface up in a valve with flow-up construction (figure6).

� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction(figure 6).

Lapping Metal Seats (C-sealConstructions)Before installing a new C-seal plug seal, lap thelower seating surface (valve plug to seat ring, figure10) following appropriate procedures in the LappingMetal Seats section of this manual.

Remachining Metal Seats (C-sealConstructions)See figure 11. A valve plug with a C-seal metal plugseal features two seating surfaces. One seatingsurface is found where the valve plug contacts theseat ring. The second seating surface is foundwhere the C-seal plug seal contacts the upperseating surface in the cage. If you machine the seats


17

on the seat ring and/or plug, you must machine anequal dimension from the seating area in the cage.

CAUTION

If metal is removed from the seat ringand plug and a corresponding amountis not removed from the cage seatingarea, the C-seal plug seal will becrushed as the valve closes and theC-seal retainer will strike the seatingarea of the cage, preventing the valvefrom closing.

Trim Replacement (C-sealConstructions)1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also,lubricate the outside diameter of the valve plugwhere the C-seal plug seal must be pressed into theproper sealing position (figure 6).

2. Orient the C-seal plug seal for correct sealingaction based on the process fluid flow directionthrough the valve.

� The open interior of the C-seal plug seal mustface up in a valve with flow-up construction (figure 6).

� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction(figure 6).

Note

An installation tool must be used toproperly position the C-seal plug sealon the valve plug. A tool is available asa Fisher spare part or a tool could bemanufactured following thedimensions given in figure 7.

3. Place the C-seal plug seal over the top of thevalve plug and press it onto the plug using theinstallation tool. Carefully press the C-seal plug sealonto the plug until the installation tool contacts thehorizontal reference surface of the valve plug (figure 8).

4. Apply a suitable high-temperature lubricant to thethreads on the plug. Then, place the C-seal retaineronto the plug and tighten the retainer using anappropriate tool such as a strap wrench.

5. Using an appropriate tool such as a centerpunch, stake the threads on top of the plug in oneplace (figure 9) to secure the C-seal retainer.

6. Replace the piston ring(s) following instructions inthe Trim Replacement section of this manual.

7. Return the seat ring, cage, plug/retainerassembly, and stem to the valve body andcompletely reassemble the valve package followingthe appropriate instructions in the Trim Replacementsection of this manual.

CAUTION

To avoid excessive leakage and seaterosion, the valve plug must beinitially seated with sufficient force toovercome the resistance of the C-sealplug seal and contact the seat ring.You can correctly seat the valve plugby applying the full actuator load. Thisforce will adequately drive the valveplug to the seat ring, thus giving theC-seal plug seal a predeterminedpermanent set. Once this is done, theplug/retainer assembly, the cage, andthe seat ring become a matched set.

With full actuator force applied and the valve plugfully seated, align the actuator travel indicator scalewith the lower end of valve travel. Refer to theappropriate actuator instruction manual forinformation on this procedure.

However, never reuse anold adaptor with a new valve plug.Using an old adaptor with a new valveplug requires drilling a new pin hole inthe adaptor. This drilling weakens theadaptor and may cause failure inservice. However, a used valve plugmay be reused with a new adaptor.

3. Inspect the existing valve plug and adaptor. Ifthey are in good condition, they can be reused withthe new stem/bellows assembly and they do notneed to be separated.

CAUTION

When removing/installing a valve plugon the ENVIRO-SEAL stem/bellowsassembly, the valve stem must not berotated. Damage to the bellows mayresult.

Do not grip the bellows shroud orother parts of the stem/bellowsassembly. Grip only the flat areas onthe stem where it extends out of thetop of the bellows shroud.

Note

The ENVIRO-SEAL stem/bellowsassembly has a one-piece stem.

4. If the valve plug and adaptor are not in goodcondition and must be replaced, the valveplug/adaptor assembly must first be removed fromthe stem/bellows assembly and then the valve plugremoved from the adaptor. First, place thestem/bellows assembly and valve plug in a soft-jawchuck or other type of vise so that the jaws grip aportion of the valve plug that is not a seating surface.Drive out or drill out the pin (key 8, figure 19, 20, or21). Drive out the pin (key 36, figure 18).

5. Then, reverse the stem/bellows and plug/adaptorassembly in the soft-jaw chuck or vise. Grip the flatareas on the valve stem just below the threads forthe actuator/stem connection. Unscrew theplug/adaptor assembly from the stem/bellowsassembly. Unscrew the valve plug from the adaptor.


21

6. To attach either the existing or a new valve plugto the stem of the new ENVIRO-SEAL stem/bellowsassembly, first attach the plug to the adaptor (if thevalve plug was removed from the adaptor) asfollows:

� Locate the adaptor. Notice that a hole has notbeen drilled in the new adaptor threads where theplug screws onto the adaptor.

� Secure the valve plug in a soft-jaw chuck orother type of vise. Do not grip the plug on anyseating surface. Position the plug in the chuck orvise for easy threading of the adaptor.

� Thread the adaptor into the valve plug andtighten to the appropriate torque value.

7. Complete the installation by following steps 7through 15 of the ENVIRO-SEAL Bellows SealBonnet installation instructions given above.

Purging the ENVIRO-SEAL Bellows SealBonnetThe ENVIRO-SEAL bellows seal bonnet has beendesigned so that it can be purged or leak tested.Refer to figure 18 for an illustration of anENVIRO-SEAL bellows seal bonnet. Perform thefollowing steps for purging or leak testing.

1. Remove the two diametrically opposed pipe plugs(key 16).

2. Connect a purging fluid to one of the pipe plugconnections.

3. Install appropriate piping or tubing in the otherpipe plug connection to pipe away the purging fluidor to make a connection to an analyzer for leaktesting.

4. When purging or leak testing has beencompleted, remove the piping or tubing and reinstallthe pipe plugs (key 16).

Parts OrderingEach valve body-bonnet assembly is assigned aserial number which can be found on the valve. Thissame number also appears on the actuatornameplate when the valve is shipped from thefactory as part of a control valve assembly. Refer tothe serial number when contacting your Fisherrepresentative for technical assistance. Whenordering replacement parts, refer to the serialnumber and to the eleven-character part number foreach part required from the following Parts Kit orParts List information.
