Additional Specifications
For specifications such as materials, valve plugtravels, and port, yoke boss, and stem diameters,see the Parts List section
1. The pressure or temperature limits in this manual and any applicable standard limitations should not be exceeded.2. Modified equal percentage characteristic is equal-percentage for the first 90% of travel, then quick-opening for additional capacity.
The Design EHS valve uses an unbalanced valveplug. To provide a seal between the cage and abalanced valve plug, the Design EHD valve pluguses piston rings; the Design EHT valve plug uses apressure-assisted seal ring. A Whisper Trim cagecan be used with a Design EHD, EHS, or EHT valveplug. A Cavitrol III cage can be used with a DesignEHS or EHT valve plug.
C-seal trim is available for Design EHD valves, class2500, in sizes 4, 6, 6x4, and 8x6.
With C-seal trim, a balanced valve can achievehigh-temperature, Class V shutoff. Because theC-seal plug seal is formed from metal (N07718nickel alloy, Inconel 718) rather than an elastomer,avalve equipped with the C-seal trim can be appliedin processes with a fluid temperature of up to 593�C(1100�F), provided other material limits are notexceeded.

Installation
WARNING
Always wear protective gloves,clothing, and eyewear whenperforming any installation operationsto avoid personal injury.
To avoid personal injury or propertydamage resulting from the suddenrelease of pressure, do not install thevalve assembly where serviceconditions could exceed the limitsgiven in this manual or on theappropriate nameplates. Usepressure-relieving devices as requiredby government or accepted industrycodes and good engineering practices.
Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.
CAUTION
The valve configuration andconstruction materials were selectedto meet particular pressure,temperature, pressure drop, andcontrolled fluid conditions specified inthe customer’s order. Responsibilityfor the safety of process media andcompatibility of valve materials withprocess media rests solely with thepurchaser and end-user. Becausesome body/trim material combinationsare limited in their pressure drop andtemperature range capabilities

(especially due to differences inthermal expansion rates), do not applyany other conditions to the valvewithout first contacting your Fishersales office.
Fisher does not assume finalresponsibility for the selection, use, ormaintenance of any product. Finalresponsibility for the selection, use,and maintenance of any Fisherproduct remains with the purchaserand end-user.
CAUTION
If hoisting the valve, use a nylon slingto protect the painted surfaces.Carefully position the sling to preventdamage to the tubing or anyaccessories. Also, take precautions toprevent personnel from being injuredin case the hoist or rigging slipsunexpectedly. Refer to table 6 for valveassembly weights. Using adequatelysized hoists and chains or slings tohandle the valve is important.
1. Before installing the valve, inspect it to ensurethat the valve body cavity is free of foreign material.
2. Clean out all pipelines to remove scale, weldingslag, and other foreign materials before installing thevalve.
Note
If the valve being installed has smallinternal flow passages, such as withWhisper Trim III or Cavitrol III cages,consideration should be given toinstalling an upstream strainer toprevent the lodging of particles inthese passages. This is especiallyimportant if the pipeline cannot bethoroughly cleaned or if the flowingmedium is not clean.
3. The control valve must be installed with theactuator vertical above the valve body for properoperation. Flow through the valve must be in thedirection indicated by the flow arrow (key 15, figure17, 18, or 19) on the valve body.
4. Use accepted piping and welding practices wheninstalling the valve in the line. For welding end valvebodies, completely disassemble the valve removing
all trim parts before welding the valve body in theline. For flanged valve bodies, use suitable gasketsbetween the valve body flanges and pipelineflanges.
Note
Depending on valve body materialsused, post-weld heat treating might beneeded. Post-weld heat treatment candamage internal elastomeric, plastic,and metal parts. Shrunk-fit pieces andthreaded connections might loosen. Ingeneral, if post-weld heat treating isneeded, remove all trim parts. Contactyour Fisher sales office for additionalinformation.
5. Install a three-valve bypass around the valve ifcontinuous operation is required duringmaintenance.
6. If the actuator and valve body are shippedseparately, refer to the actuator mounting procedurein the appropriate actuator instruction manual.
WARNING
Personal injury could result frompacking leakage. Valve packing wastightened prior to shipment; howeversome readjustment will be required tomeet specific service conditions.Check with your process or safetyengineer for any additional measuresthat must be taken to protect againstprocess media.
7. If the valve was shipped without packing installedin the packing box, install the packing before puttingthe valve into service. Refer to instructions given inthe Packing Maintenance procedure.
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, adding packing rings, replacingpacking, trim removal, valve plug maintenance,lapping seats, and trim replacement. Allmaintenance operations can be performed with thevalve in the line.

� 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, a new gasket should be installedupon reassembly. This is necessary toensure a good gasket seal.
Note
If the valve has HIGH-SEAL heavy-dutylive-loaded packing installed, seeFisher instruction manual entitledHIGH-SEAL Live-Loaded PackingSystem’ for packing instructions.
Packing Lubrication
Note
To avoid lubricants breaking down atelevated temperatures, do notlubricate packing used in processeswith temperatures over 260�C (500�F).
A lubricator or lubricator/isolating valve (figure 2) isrecommended for PTFE-composition packing. Thelubricator or lubricator/isolating valve is installed inplace of the pipe plug (key 14, figure 15). It is
EH Valve (1-1/2 x 1 through 8 x 6)Instruction Manual
Form 5163July 2002

recommended that a good quality silicon-baselubricant be used. To operate the lubricator, simplyturn the cap screw clockwise to force lubricant intothe packing box. The lubricator/isolating valveoperates the same way except the isolating valvemust first be opened and then closed afterlubrication is completed.
Packing MaintenanceIf there is undesirable packing leakage inspring-loaded PTFE V-ring packing (figure 3), tightenthe packing flange nuts (key 5, figure 15) until theshoulder on the packing follower (key 13, figure 15)contacts the bonnet (key 1, figure 15). If leakagecontinues, replace the packing by following thenumbered steps presented in the Replacing Packingprocedure.
If there is undesirable packing leakage with otherthan spring-loaded PTFE V-ring packing, first try tolimit the leakage and establish a stem seal bytightening the packing flange nuts (key 5, figure 15)to at least the minimum recommended torque intable 7. However, do not exceed the maximumrecommended torque in table 7 or excessive frictionmay result. If leakage continues, replace the packingby following the numbered steps presented in theReplacing Packing procedure.
If the packing is relatively new and tight on the valveplug stem, and if tightening the packing flange nutsdoes not stop the leakage, it is possible that thestem is worn or nicked so that a seal cannot bemade. The surface finish of a stem is critical formaking a good packing seal. If the leakage comesfrom the outside diameter of the packing, it ispossible that the leakage is caused by nicks orscratches around the packing box wall. Whilereplacing the packing according to the ReplacingPacking procedure, inspect the valve plug stem andpacking box wall for nicks or scratches.
Replacing PackingKey numbers referred to in this procedure are shownin figure 15 unless otherwise indicated.
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.
Remove the cap screws in the stem connector, andseparate the two halves of the stem connector. Thenexhaust all actuator pressure, if any was applied,
and disconnect the actuator supply and any leakoffpiping.
2. Remove either the yoke locknut (key 15) or thehex nuts (key 26), and remove the actuator from thebonnet (key 1).
3. Loosen the packing flange nuts (key 5) so thatthe packing is not tight on the valve plug stem (key4, figure 17, 18, or 19). Remove any travel indicatordisk and stem locknuts from the valve plug stemthreads.
CAUTION
When lifting the bonnet (key 1), besure that the valve plug and stemassembly (keys 3 and 4, figure 17, 18,or 19) remains on the seat ring (key 6,figure 17, 18, or 19). This avoidsdamage to the seating surfaces as aresult of the assembly dropping fromthe bonnet after being lifted part wayout. The parts are also easier to handleseparately.
Use care to avoid damaging gasketsealing surfaces.
The Design EHD piston rings (key 8,figure 17) are brittle and in two pieces.Avoid damaging the piston rings bydropping or rough handling.
WARNING
If the cage adheres to the bonnet asthe bonnet is lifted, secure the cage tothe bonnet so that it will not causepersonal injury or equipment damageshould it fall unexpectedly.
4. Unscrew the hex nuts (key 14, figure 17, 18, or19) and carefully lift the bonnet off the valve stem. Ifthe valve plug and stem assembly starts to lift withthe bonnet, use a brass or lead hammer on the endof the stem and tap it back down. Set the bonnet ona cardboard or wooden surface to prevent damageto the bonnet gasket surface.
5. Remove the valve plug (key 3, figure 17, 18, or19), the cage (key 2, figure 17, 18, or 19), and thetop and bottom cage gaskets (key 11, figure 17, 18,or 19).

CAUTION
All residual gasket material must beremoved from the the cage gasketsurfaces. If the gasket surfaces arescored or damaged during thisprocess, smooth them by handsanding with 360 grit paper using long,sweeping strokes. Failure to removeall residual gasket material and/orburrs from the gasket surfaces willresult in leakage.
6. Clean all gasket surfaces with a good qualitydegreaser. Remove all residual tin or silver from allgasket surfaces.
7. Cover the opening in the valve body to protectthe gasket surface and to prevent foreign materialfrom getting into the valve body cavity.
8. Remove the packing flange nuts (key 5), packingflange (key 3), upper wiper (key 12), and packingfollower (key 13, figures 3 and 15). Carefully pushout all the remaining packing parts from the valveside of the bonnet using a rounded rod or other toolthat will not scratch the packing box wall. Forextension bonnets, also remove the baffle (key 2)and retaining ring (key 35).
9. Clean the packing box and the following metalpacking parts: packing follower (key 13), packingbox ring (key 11), spring or lantern ring (key 8,figures 3 and 15), and, for single arrangements ofPTFE V-ring packing only, special washer (key 10,figures 3 and 15).
10. Inspect the valve stem threads for any sharpedges that might cut the packing. A whetstone oremery cloth may be used to smooth the threads ifnecessary.
11. Remove the protective covering from the valvebody cavity. Using new top and bottom cage gaskets(key 11, figure 17, 18, or 19), place the cage into thevalve body. Be sure the cage lugs are engaged inthe corresponding recesses of the seat ring retainer.Turn the cage clockwise until the lugs contact theseat ring retainer. Install the plug, then slide thebonnet over the stem and onto the studs (key 13,figure 17, 18, or 19).
Note
The prelubricated hex nuts (key 14,figure 17, 18, or 19) referred to in step12 can be identified by a black filmcoating on the nut threads.The proper bolting procedures in step12 include—but are not limitedto—ensuring that the bonnet studthreads are clean, and that the hexnuts are evenly tightened to thespecified torque values.
CAUTION
Failure to comply with goodbonnet-to-body bolting practices andthe torque values shown in table 8 mayresult in cage crushing, cage diameterreduction, and/or bonnet deformation.Cheater bars or slug wrenches shouldnot be used for this procedure.Hot torquing is not recommended.
12. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 17, 18, or 19) withNever-Seez Pure Nickel Special lubricant orequivalent (not necessary if new factoryprelubricated hex nuts are used). Replace thewashers and hex nuts but do not tighten them.Torque the nuts in a crisscross pattern to no morethan 1/4 of the nominal torque value specified intable 8. When all nuts are tightened to that torquevalue, increase the torque by 1/4 of the specifiednominal torque and repeat the crisscross pattern.Repeat this procedure until all nuts are tightened tothe specified nominal value. Apply the final torquevalue again and, if any nut still turns, tighten everynut again.
Note
If graphite ribbon/filament packingrings are used, special proceduresmust be observed to prevententrapping air between the rings. Addthe rings one at a time without forcingthem below the chamfer of the packingbox entrance chamber. As eachsuccessive ring is added, the stackshould not be pushed down more thanthe thickness of the added ring (figure 4).

13. Install new packing and the metal packing boxparts according to the appropriate arrangement infigure 3. If desired, packing parts may bepre-lubricated with a silicon base grease for easierinstallation. Slip a smooth-edged pipe over the valvestem, and gently tamp each soft packing part intothe packing box, being sure that air is not trappedbetween adjacent soft parts. For a valve withextension bonnet, also install the baffle and retainingrings (keys 2 and 35).
14. Slide the packing follower, wiper, and packingflange into position. Lubricate the packing flangestuds (key 4) and the faces of the packing flangenuts (key 5). Replace the packing flange nuts.
For spring-loaded PTFE V-ring packing, tightenthe packing flange nuts until the shoulder on thepacking follower (key 13) contacts the bonnet.
For other packing types, tighten the packing flangenuts to the maximum recommended torque shown intable 7. Then, loosen the packing flange nuts, andretighten them to the recommended minimum torqueshown in table 7.
15. Mount the actuator on the valve body assembly,and reconnect the actuator and valve plug stemsaccording to the procedures in the appropriateactuator instruction manual.
Trim RemovalFor C-seal construction, see the appropriateC-seal sections in this instruction manual.
Trim removal and replacement requires the use of aseat ring retainer tool (key 25). If specificallyordered, a tool is supplied with a valve; but, the toolcan also be ordered separately by referencing the
tool part number in the Parts List. If desired, a toolcan also be machined for a valve of specific size andvalve class using the dimensions shown in figure 8.Machine the tool from a material listed in figure 8 orfrom a material with a yield strength of at least 827MPa (120,000 psi). Using a tool of lower strengthmaterial may result in damage to the seat ringretainer or valve body threads.

2. To replace the valve plug stem (key 4), drive outthe pin (key 5), and unscrew the stem from the valveplug.
CAUTION
Never reuse an old stem with a newvalve plug. Using an old stem with anew plug requires drilling a new pinhole in the stem. This weakens thestem and may cause the stem to fail inservice. If a new valve plug is required,always order a valve plug, stem, andpin as an assembly. Specify thecorrect part number of each of thethree parts, but state that the parts arebeing ordered as an assembly.
A used valve plug may be reused witha new stem. An exception is theCavitrol III plug/stem assembly whichmust be ordered and replaced as aunit.
3. Thread the new stem into the valve plug andtighten it to the appropriate torque value given intable 10. Using the valve plug pin hole as a guide,drill the pin hole through the stem. Refer to table 10for drill sizes.4. Drive in the pin to lock the assembly.5. If it is necessary to lap the seating surfaces,complete the Lapping Seats procedure beforeinstalling the Design EHD piston rings or the DesignEHT seal ring. The Trim Replacement procedureprovides piston ring and seal ring installationinstructions and valve reassembly instructions.
Lapping SeatsKey numbers referenced in this procedure areshown in figure 17 for the Design EHD valve, infigure 18 for the Design EHS valve, and in figure 19for the Design EHT valve unless otherwise indicated.Seating surfaces of the valve plug (key 3) and theseat ring (key 6) can be lapped for improved shutoff.Use a good quality lapping compound with a mixturethat contains 280 to 600 grit. Apply the compound tothe bottom of the valve plug. Use the followingprocedure to lap the seating surfaces.1. Install the following parts according to theinstructions presented in the Trim Replacementprocedure: seat ring gasket or O-ring (key 12), seatring (key 6), seat ring retainer (key 7), cage (key 2),cage gaskets (key 11), and if used, the O-ring (key26, figure 20).2. Proceed as appropriate:For a Design EHD or EHT valve, install the valveplug and stem assembly (keys 3 and 4)—withoutpiston rings or seal ring (keys 8 and 30)—into thecage.For a Design EHS valve, install the valve plug andstem assembly (keys 3 and 4) into the cage.3. Install the bonnet (key 1, figure 15) over the valvestem, and secure the bonnet with four of the hexnuts (key 14).4. Attach a handle, such as a piece of strap ironsecured by stem locknuts, to the valve stem. Rotatethe handle alternately in each direction to lap theseats.
Note
To preserve the effects of lapping, donot change either the position of the

5. After lapping, again disassemble as necessary,clean the seating surfaces, reassemble, and test forshutoff. Repeat the lapping procedure if necessary.
Trim ReplacementAfter all trim maintenance has been completed,reassemble the valve by following the numberedsteps below. Be certain that all gasketed surfaceshave been well cleaned. Key numbers referenced inthis procedure are shown in figure 17 for the DesignEHD valve, in figure 18 for the Design EHS valve,and in figure 19 for the Design EHT valve.
CAUTION
Thoroughly clean the seat ring (key 6),seat ring retainer (key 7), and theretainer threads in the valve body witha good-quality degreaser. Also cleanall cage gasket surfaces. All residualgasket material must be removed fromthe cage gasket surfaces and, ingasketed seat ring constructions, fromthe serrated valve body and seat ringgasket surfaces. If the serrations arescored or damaged during thisprocess, smooth them by handsanding with 360 grit paper using long,sweeping strokes. Failure to removeall residual gasket material and/orburrs from the seat ring, cage, andvalve body gasket surfaces will resultin leakage.
Thoroughly lubricate the surfacesindicated in figure 7 with theappropriate lubricant shown in table11. Be certain to lubricate the matingsurfaces of both parts involved (i.e.,lubricate the threads on the seat ringretainer and the threads in the valvebody; lubricate the mating surfaces ofthe seat ring retainer and seat ring).

CAUTION
Hold the torque wrench at right anglesto the seat ring retainer when applyingtorque. Tilting the tool and extensionwhile applying torque may cause thelugs on the seat ring retainer tool tosuddenly disengage from the recessesin the retainer, damaging the retainerand seat ring.
e. Tighten the seat ring retainer to the torqueshown in table 9.
Note
Some cages have one large windowand several small windows. In step 2,install a cage that has different sizewindows so that the largest windowfaces toward the process outlet for aflow-down and toward the processinlet for a flow-up valve. Though it maynot be possible to align the largewindow directly opposite the inlet oroutlet, orient the window in theappropriate direction as much aspossible. Incorrect orientation of cagewindows causes a reduction ofcapacity.
2. Proceed as appropriate:
For a valve with a Cavitrol III cage, slide the O-ring(key 26, figure 20) over the seat ring (key 6) andagainst the shoulder in the outer diameter of the seatring. Install the lower gasket (key 11) between thevalve body and cage (key 2), and install the cage.Be certain the lugs on the bottom of the cageengage the corresponding slots in the seat ringretainer.
For all other valves, install the lower gasket (key11) between the valve body and cage (key 2), andinstall the cage. Be certain the lugs on the bottom ofthe cage engage the corresponding slots in the seatring retainer.
Note
Rotate the cage clockwise by hand asmuch as possible once the cage lugsengage the slots in the seat ringretainer. Failure to do so may result inleakage at the seat ring to valve bodyseal.
Constructions other than TSO trim1. To install the piston rings and seal rings (keys 8and 30), proceed as appropriate:
For a Design EHD valve (figure 17), if it isnecessary to install new piston rings, thereplacement piston rings will arrive in one piece. Usea vise with smooth or taped jaws to break areplacement piston ring into halves. Place the newring in the vise so that the jaws compress the ringinto an oval. Compress the ring slowly until the ringsnaps on both sides. If one side snaps first, do nottry to tear or cut the other side. Instead, keepcompressing until the other side snaps. The pistonring can also be fractured by scoring and snappingover a hard surface such as a table edge. Sawing orcutting is not recommended.
Remove any protective tape or covering from thevalve plug and stem assembly, and set it on aprotective surface. Then, place the piston ring in thepiston ring groove with the fractured ends matched.
For a Design EHT valve (figure 19), install the sealring (key 8) onto the valve plug (key 3). Install thering with the open side facing the seat ring end ofthe valve plug for flow-down applications (view A offigure 19) or with the open side facing the valve plugstem end of the valve plug for flow-up applications.Slide the backup ring (key 9) onto the valve plug.Secure with the retaining ring (key 10). For a 6-inchvalve with a level D Whisper Trim III cage, reinstallthe piston ring (key 30) following the instructionsgiven in the paragraph immediately preceding.
2. Install the valve plug into the cage.
TSO TrimRefer to figure 6.
1. Thread the outer plug onto the inner plug until theparts seat metal to metal, using a strap wrench orsimilar tool that will not damage the outer plug guidesurfaces.
2. Mark the top of the inner plug and outer plug withalignment marks in the assembled position.
3. Disassemble the outer plug from the inner plugand install the seal over the inner plug, so that theseal rests below the threaded area.
4. Thread the outer plug onto the inner plug andtighten with a strap wrench or similar tool until thealignment marks line up. This will ensure that theplug parts are metal to metal and the seal iscompressed properly. Do not damage the outer plugguide surfaces.

5. Install set screws centering the inner plug in theouter plug and torque to 11 N�m (8 lbf�ft).
6. Assemble the piston ring, anti-extrusion rings,backup ring, and retainer.
All Constructions1. Install the top cage gasket (key 11) on the cage.
2. Install the bonnet over the valve stem and ontothe valve body.
Note
The prelubricated hex nuts (key 14,figure 17, 18, or 19) referred to in step7 can be identified by a black filmcoating on the nut threads.
The proper bolting procedures in step7 include—but are not limitedto—ensuring that the bonnet studthreads are clean, and that the hexnuts are evenly tightened to thespecified torque values.
CAUTION
Failure to comply with goodbonnet-to-body bolting practices andthe torque values shown in table 8 mayresult in cage crushing, cage diameterreduction, and/or bonnet deformation.Cheater bars or slug wrenches shouldnot be used for this procedure.
Hot torquing is not recommended.
3. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 17, 18, or 19) withNever-Seez Pure Nickel Special lubricant orequivalent (not necessary if new factoryprelubricated hex nuts are used). Replace thewashers and hex nuts but do not tighten them.Torque the nuts in a crisscross pattern to no morethan 1/4 of the nominal torque value specified intable 8. When all nuts are tightened to that torquevalue, increase the torque by 1/4 of the specifiednominal torque and repeat the crisscross pattern.Repeat this procedure until all nuts are tightened tothe specified nominal value. Apply the final torquevalue again and, if any nut still turns, tighten everynut again.
4. Install new packing and packing box parts persteps 12 and 13 of the Replacing Packing
procedure. Be certain to observe the note given priorto step 12 of that procedure.
5. Mount the actuator by following the procedures inthe actuator instruction manual. Check for packingleakage as the valve is being put into service.Retorque the packing flange nuts as required (seetable 7).
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 9).
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 (figure9).
� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction(figure 9).

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 using the same force calculated forfull load when sizing your actuator.With no pressure drop through thevalve, this force will adequately drivethe valve plug to the seat ring, thusgiving the C-seal plug seal apredetermined permanent set. Oncethis is done, the plug/retainer
assembly, the cage, and the seat ringbecome a matched set.
12. With full actuator force applied and the valveplug fully seated, align the actuator travel indicatorscale with the lower end of valve travel. Refer to theappropriate actuator instruction manual forinformation on this procedure.
Replacement of Installed C-seal Trim

CAUTION
To avoid leakage when the valve isreturned to service, use appropriatemethods and materials to protect allsealing surfaces of the trim partsduring maintenance.
Use caution when removing pistonring(s) and C-seal plug seal to avoidscratching any sealing surface.
CAUTION
Do not remove the valve stem from theplug/retainer assembly unless you areplanning to replace the valve stem.
Never reuse an old valve stem with anew plug or reinstall a valve stem afterit has been removed. Replacing a valvestem requires drilling a new pin hole inthe stem. This drilling weakens thestem and may cause failure in service.However, a used valve plug may bereused with a new valve stem.

2. Remove the plug/retainer assembly (with C-sealplug seal), cage, and seat ring from the valve bodyfollowing the appropriate instructions in the TrimRemoval section of this manual.
3. Locate the staked thread on top of the valve plug(figure 12). The staked thread secures the retainer.Use a drill with a 1/8-inch bit to drill out the stakedarea of the thread. Drill approximately 1/8-inch intothe metal to remove the staking.
4. Locate the break between sections of the pistonring(s). Using an appropriate tool such as aflat-blade screwdriver, carefully pry out the pistonring(s) from the groove(s) in the C-seal retainer.
5. After removing the piston ring(s), locate the0.25-inch diameter hole in the groove. In a retainerwith two piston ring grooves, the hole will be found inthe upper groove.
6. Select an appropriate tool such as a punch andplace the tip of the tool into the hole with the body ofthe tool held tangent to the outside diameter of theretainer. Strike the tool with a hammer to rotate theretainer and free it from the valve plug. Remove theretainer from the plug.
7. Use an appropriate tool such as a flat-bladescrewdriver to pry the C-seal plug seal off the plug.Use caution to avoid scratches or other damage tothe sealing surfaces where the C-seal plug sealmakes contact with the valve plug (figure 13).
8. Inspect the lower seating surface where the valveplug contacts the seat ring for wear or damage

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 9).
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 (figure9).
� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction(figure 9).
Note
An installation tool must be used toproperly position the C-seal plug sealon the valve plug. A tool is available asa spare part from Fisher or a tool couldbe manufactured following thedimensions given in figure 10.
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 (figure11).
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 12) 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 be
initially seated with sufficient force toovercome the resistance of the C-sealplug seal and contact the seat ring.You can correctly seat the valve plugby using the same force calculated forfull load when sizing your actuator.With no pressure drop through thevalve, this force will adequately drivethe valve plug to the seat ring, thusgiving the C-seal plug seal apredetermined permanent set. Oncethis is done, the plug/retainerassembly, the cage, and the seat ringbecome a matched set.
With full actuator force applied and thevalve plug fully seated, align theactuator travel indicator scale with thelower end of valve travel. Refer to theappropriate actuator instructionmanual for information on thisprocedure.
