Tightening ProcedureTo obtain the target load of 85% compression ofmaximum deflection, perform the following:

� Tighten the packing flange nuts alternately andevenly, keeping the packing flange parallel with thevalve flange, until the Belleville springs arecompressed 100% (or completely flat), as detectedby a rapid increase in nut torque. Refer to theinstruction manual for ENVIRO-SEAL packingsystems for sliding stem valves if you need furtherassistance.

� For graphite ULF packing, loosen each packingflange nut 1/4 turn (90 degrees rotation).

The ‘‘target load’’ of 85% compression has nowbeen reached.

1. The “springs flat” procedure described above isthe preferred method of adjusting ENVIRO-SEALGraphite ULF packing. However, the torque valuesin table 1 can also be used as a guideline for 85%spring compression. These values are based ongenerous lubrication of the packing studs and nutswith Never-Seez lubricant. Loosening of the packingflange nuts is not required when these torques areused.

2. Refer to the appropriate valve and actuatorinstruction manuals when connecting the valve tothe actuator. Under normal conditions, the packingnuts should not require re-tightening.

DescriptionThe Design EHD and EHT valves, shown in figure 1,are large, sliding-stem, high-pressure, globe-stylevalves. These valves have metal seats, cage guiding,and push-down-to-close valve plug action.

The Design EHD and EHT valves feature balancedvalve plugs. To provide a seal between the valve plugand cage, the Design EHD valve plug has piston rings;the Design EHT valve plug has a pressure-assistedseal ring.

C-seal trim is available for Design EHD valves, class1500, in sizes 8 and 10 and class 2500, in sizes 8, 10,12, and 14.

With C-seal trim, a balanced valve can achieve high-temperature, Class V shutoff. Because the C-seal plugseal is formed from metal (N07718 nickel alloy, Incon-el 718) rather than an elastomer, a valve equippedwith the C-seal trim can be applied in processes with afluid temperature of up to 593�C (1100�F), providedother material limits are not exceeded.

SpecificationsSpecifications for the Design EHD and EHT valves areshown in table 1.

Installation

WARNING

To avoid personal injury or propertydamage resulting from the sudden re-lease of pressure, do not install thevalve assembly where service condi-tions could exceed the limits given inthis manual or on the appropriate name-plates. Use pressure-relieving devicesas required by government or acceptedindustry codes and good engineeringpractices.

CAUTION

The valve configuration and construc-tion materials were selected to meet par-ticular pressure, temperature, pressuredrop, and controlled fluid conditions.Because some body/trim material com-binations are limited in their pressuredrop and temperature range capabilities,do not apply any other conditions to thevalve without first contacting yourFisher Controls sales office or salesrepresentative.

If hoisting the valve, use a nylon sling toprotect the painted surfaces. Carefullyposition the sling to prevent damage tothe actuator tubing or any accessories.Also, take precautions to prevent per-sonnel from being injured in case thehoist or rigging slips unexpectedly. Re-fer to table 4 for valve assembly weightsand the appropriate actuator instructionmanual for actuator assembly weights.Be sure to use adequately sized hoistsand chains or slings to handle the valveand actuator assembly.

1. Before installing the valve, inspect the valve, bodycavity, and associated equipment for any damage andforeign material.

2. Clean out all pipelines to remove scale, weldingslag, and other foreign materials before installing thevalve.

Note

If installing a valve with small internalflow passages, such as with WhisperTrim III or Cavitrol� III cages, considerinstalling an upstream strainer to pre-vent the lodging of particles in thesepassages. This is especially important ifthe pipeline cannot be thoroughlycleaned or if the flowing medium is notclean.

3. Install the control valve with the valve body in ahorizontal pipeline and the actuator vertical above thevalve. Other orientations may result in shortened trimlife and difficulty with field maintenance. Flow throughthe valve body must be in the direction indicated bythe flow arrow (key 15, figure 14 or 15) on the valvebody.

Note

Depending on valve body materialsused, post-weld heat treating might beneeded. Post-weld heat treatment candamage internal elastomeric, plastic,and metal parts. Shrink-fit pieces andthreaded connections might also loos-en. In general, if post-weld heat treatingis needed, remove all trim parts. Contactyour Fisher Controls sales office orsales representative for additional in-formation.

4. Use accepted piping and welding practices wheninstalling the valve in the line. For flanged valve bo-dies, use suitable gaskets between the valve bodyflanges and pipeline flanges.

5. Install a three-valve bypass around the controlvalve if continuous operation is required during mainte-nance.

6. If the actuator and valve are shipped separately,see the Actuator Mounting procedure.

7. If the valve was shipped without packing installed inthe packing box, install the packing prior to putting the


4

valve into service. Refer to instructions given in thePacking Maintenance section of this manual.

Principle of OperationKey numbers referenced in this section are shown infigure 14 for the Design EHD valve and in figure 15 forthe Design EHT valve.

Design EHD and EHT valves are balanced designs.When they are opening or closing, pressure registerson top of the valve plug (key 3) through the registra-tion holes in the plug. The force of the pressure on topof the plug balances the force of the pressure on thebottom of the plug to reduce the actuator force requi-red.

MaintenanceValve parts are subject to normal wear and must beinspected and replaced as necessary. Inspection andmaintenance frequency depends on the severity ofservice conditions. This section includes instructionsfor packing lubrication and maintenance, trim mainte-nance, and lapping of metal seats. All maintenanceoperations can be performed with the valve in the line.

Because of the care Fisher Controls takes in meetingall manufacturing requirements (heat treating, dimen-sional tolerances, etc.), use only replacement partsmanufactured or furnished by Fisher Controls.

WARNING

Avoid personal injury from sudden re-lease of process pressure. Before per-forming any maintenance operations:

� Disconnect any operating lines pro-viding air pressure, electric power, or acontrol signal to the actuator. Be surethe actuator cannot suddenly open orclose the valve.

� Use bypass valves or completelyshut off the process to isolate the valvefrom process pressure. Relieve processpressure on both sides of the valve.Drain the process media from bothsides of the valve.

� Vent the power actuator loadingpressure and relieve any actuator springprecompression.

� Use lock-out procedures to be surethat the above measures stay in effectwhile you work on the equipment.

Refer to table 4 for valve assemblyweights and the appropriate actuatorinstruction manual for actuator assem-bly weights. Due to the size and weightof the valve and actuator assembly, besure adequately sized hoists and chainsor slings are used to handle it. Also,take proper precautions to prevent per-sonnel from being injured if the hoist orrigging slips unexpectedly.

Note

Whenever a gasket seal is disturbed byremoving or shifting gasketed parts,install a new gasket upon reassembly.This is necessary to ensure a good gas-ket seal.

8. After all maintenance is complete, refer to the TrimReplacement procedure to assemble the valve body.

Note

If the valve has ENVIRO-SEAL� live-loaded packing installed, see the FisherControls instruction manual titledENVIRO-SEAL Packing System for Slid-ing-Stem Valves for packing instruc-tions.

If the valve has HIGH-SEAL� live-loadedpacking installed, see the FisherControls instruction manual titledHIGH-SEAL Live-Loaded Packing Sys-tem for instructions.

Packing Lubrication

Note

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

A lubricator or lubricator/isolating valve (figure 2) isrecommended for PTFE-impregnated compositionpacking. The lubricator or lubricator/isolating valve isinstalled in place of the pipe plug in the bonnet. Use agood quality silicon-base lubricant. Do not lubricatepacking used in oxygen service or in processes withtemperatures over 260�C (500�F). To operate the lu-

bricator, turn the cap screw clockwise to force lubri-cant into the packing box. The lubricator/isolatingvalve operates the same way except open the isolat-ing valve before turning the cap screw and then closethe isolating valve after lubrication is completed.

Packing Maintenance

WARNING

Personal injury could result from pack-ing leakage. Valve packing was tight-ened before shipment; however, thepacking might require readjustment tomeet specific service conditions.

Valves with ENVIRO-SEAL live-loaded packing orHIGH-SEAL live-loaded packing installed probably willnot require this initial re-adjustment. See the FisherControls instruction manuals titled ENVIRO-SEALPacking System for Sliding-Stem Valves or HIGH-SEAL Live-Loaded Packing System (as appropriate)for packing instructions. To convert an existing pack-ing arrangement to ENVIRO-SEAL packing, refer tothe retrofit kits listed in the parts kit sub-section nearthe end of this manual. Figures 3 and 4 show typicalENVIRO-SEAL packing systems.

For spring-loaded PTFE V-ring packing (figure 6), thespring maintains a sealing force on the packing. Ifleakage is noted around the packing follower (key 13,figure 13), check to be sure the shoulder on the pack-ing follower is touching the bonnet (key 1, figure 13). Ifthe shoulder is not touching the bonnet, tighten thepacking flange nuts (key 5, figure 13) until the shoul-

der on the packing follower is against the bonnet. Ifthe packing leakage is still excessive, replace thepacking by following the Replacing Packing procedure.

If packing leakage is undesirable with other thanspring-loaded PTFE V-ring packing, first try to limit theleakage and establish a stem seal by tightening thepacking flange nuts (key 5, figure 13) to at least theminimum recommended torque in table 5. However,do not exceed the maximum recommended torque intable 5 or excessive friction may result.

If the packing is relatively new and tight on the stem,and if tightening the packing flange nuts does not stopthe leakage, the valve stem may be worn or nicked sothat a seal cannot be made. The surface finish of anew stem is critical for making a good packing seal. Ifthe leakage comes from the outside diameter of thepacking, the leakage may be caused by nicks orscratches around the packing box wall. While replac-ing the packing according to the Replacing Packingprocedure, inspect the stem and packing box wall fornicks or scratches.

Replacing Packing

Key numbers referred to in this procedure are shownin figure 13 unless otherwise indicated.

1. Remove the stem connector cap screws shown infigure 5, and separate the two halves of the stem con-nector. Then exhaust all actuator pressure, if any wasapplied, and disconnect the actuator supply and anyleakoff piping.

2. Remove the hex nuts (key 26) and remove the ac-tuator from the bonnet (key 1). Loosen the packingflange nuts (key 5) so that the packing (key 6, or 7 and 9, figure 6) is not tight on the valve plug stem (key 4, figure 14 or 15). Remove any travel indicatordisk and stem locknuts from the valve plug stemthreads.

WARNING

To avoid personal injury or propertydamage caused by uncontrolled move-ment of the bonnet, loosen the bonnetby following the instructions in the nextstep. Do not remove a stuck bonnet bypulling on it with equipment that canstretch or store energy in any othermanner. The sudden release of storedenergy can cause uncontrolled move-ment of the bonnet.

Note

The following step also provides addi-tional assurance that the valve fluidpressure has been relieved.

3. Hex nuts (key 14) attach the bonnet to the valvebody. Loosen these nuts approximately 3 mm (1/8 inch).Then loosen the body-to-bonnet gasketed joint by eitherrocking the bonnet or prying between the bonnet andvalve body. Work the prying tool around the bonnet until

the bonnet loosens. If no fluid leaks from the joint, pro-ceed with the bonnet removal in step 5.

WARNING

If the cage sticks to the bonnet, proceedcarefully with bonnet removal until thecage windows are accessible. Do notextend hands or arms through the win-dows at this point as a sudden separa-tion of bonnet and cage will cause per-sonal injury. Use a stick or other deviceto thread a rope or sling through thewindows. Use this rigging to secure thecage to the bonnet or hoist to preventdamage or injury should the cage sud-denly separate from the bonnet.

CAUTION

When lifting the bonnet (key 1), be surethat the valve plug and stem assembly(keys 3 and 4, figure 14 or 15) remainson the seat ring (key 6, figure 14 or 15).This avoids damage to the seating sur-faces as a result of the assembly drop-ping from the bonnet after being liftedpart way out. The parts are also easierto handle separately.

4. Remove the hex nuts (key 14, figure 14 or 15) andwashers (key 29, figure 14 or 15). Carefully lift thebonnet off the valve plug stem. If the valve plug as-sembly starts to lift with the bonnet, use a brass orsimilar hammer to tap the end of the stem and tap itback down. Set the bonnet on a protective surface toprevent damage to the bonnet gasket surface.

CAUTION

Use care to avoid damaging gasket seal-ing surfaces.

The Design EHD piston rings (key 8) arebrittle and in two pieces. Use care toavoid damage to the piston ringscaused by dropping or rough handling.

5. Lift the plug assembly (keys 3 and 4, figure 14 or 15) out of the valve body.

Note

Proper performance of the bolting pro-cedures in step 14 compresses the cagegaskets (key 11, figure 14 or 15) enoughto seal the body-to-bonnet joint.

The prelubricated hex nuts (key 14, fig-ure 14 or 15) referred to in step 14 canbe identified by a black film coating onthe nut threads.

The proper bolting procedures in step14 include, but are not limited to, ensur-ing that the bonnet stud threads areclean, and that the hex nuts are evenlytightened to the specified torque values.

CAUTION

Failure to comply with good bonnet-to-body bolting practices and the torquevalues shown in table 6 may result incage crushing, cage diameter reduction,and/or bonnet deformation. Do not usecheater bars or slug wrenches for thisprocedure.

Hot torquing is not recommended.

13. Lubricate the stud threads and the faces of thehex nuts (key 14, figure 14 or 15) with Never-SeezPure Nickel Special lubricant or equivalent (not neces-sary if new factory prelubricated hex nuts are used).Replace the washers and hex nuts but do not tightenthem. Torque the nuts in a crisscross pattern to nomore than 1/4 of the nominal torque value specified intable 6. When all nuts are tightened to that torque val-ue, increase the torque by 1/4 of the specified nominaltorque and repeat the crisscross pattern. Repeat thisprocedure until all nuts are tightened to the specifiednominal value. Apply the final torque value again and,if any nut still turns, tighten every nut again.

14. Install new packing and the metal packing boxparts according to the appropriate arrangement in fig-ure 6. Slip a smooth-edged pipe over the valve stem,and gently tamp each soft packing part into the pack-ing box.

15. Slide the packing follower, wiper, and packingflange into position. Lubricate the packing flange studs(key 4) and the faces of the packing flange nuts (key5) and then install the packing flange nuts.

For spring-loaded PTFE V-ring packing: Tightenthe packing flange nuts until the shoulder on the pack-ing follower (key 13) contacts the bonnet (key 1).

For other kinds of packing, except ENVIRO-SEALand HIGH-SEAL: Tighten the packing flange nuts tothe maximum recommended torque shown in table 5.Then, loosen the packing flange nuts and retightenthem to the recommended minimum torque in table 5.

For ENVIRO-SEAL and HIGH-SEAL packing: Seethe Fisher Controls instruction manuals titledENVIRO-SEAL Packing System for Sliding-StemValves or HIGH-SEAL Live-Loaded Packing System(as appropriate) for packing instructions.

16. Mount the actuator on the valve body assembly,and reconnect the actuator and valve plug stem ac-cording to the Actuator Mounting procedure. After thecontrol valve is returned to service, retighten the hexnuts (key 14, figure 14 or 15) to the torque recom-mended in table 6.

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

Key numbers referenced in this procedure are shownin figure 14 for the Design EHD valve and figure 15 forthe Design EHT valve except where indicated.

1. Remove the actuator and bonnet by following steps1 through 9 of the Replacing Packing procedure.

2. To remove the seat ring (key 6), remove the capscrews (key 7). Install eyebolts or similar devices inthe 5/8-inch 11-UNC tapped holes (9/16-inch 12-UNCfor an 8 or 10-inch Class 1500 valve). Use the eye-bolts to carefully lift the seat ring out of the valve body.If the seat ring is to be reused, exercise care to protectthe gasket surfaces on the bottom of the seat ring.

3. Remove the spiral wound seat ring gasket or O-ring (key 12).

4. Refer to the following appropriate valve plug main-tenance procedure or to the Lapping Seats procedure.

Design EHD and EHT Valve PlugMaintenanceKey numbers used in this procedure are shown in fig-ure 14 for the Design EHD valve and in figure 15 forthe Design EHT valve.

1. With the valve plug (key 3) removed per the TrimRemoval procedure, proceed as appropriate:

For the Design EHD valve, the piston rings (key 8)are each in two sections; remove the sections from thegrooves in the valve plug.

For all Design EHT valves, work the retaining ring(key 10) off the valve plug with a screwdriver. Careful-ly slide the backup ring and seal ring (keys 9 and 8) offthe valve plug. Additionally, for the Design EHT valvewith Whisper Trim Level D cage, remove the two sec-tions of the piston ring (key 30, figure 15).

2. To replace the valve plug stem (key 4), drive outthe pin (key 5) and unscrew the stem from the valveplug (key 3).

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 the stemand may cause the stem to fail in ser-vice. If a new valve plug is required, al-ways order a valve plug, stem, and pinas an assembly. Specify the correct partnumber of each of the three parts butstate that the parts are being ordered asan assembly.

A used valve plug may be reused with anew stem.

3. Thread the new stem into the valve plug until thestem wedges tightly at the end of the thread. Using thevalve plug pin hole as a guide, drill the pin holethrough the stem. Use a 1/4-inch drill for 31.8 mm(1-1/4 inch) stems and a 3/8-inch drill for 50.8 mm(2-inch) stems.

4. Drive in the pin to lock the assembly.

5. If seat lapping is necessary, complete the LappingSeats procedure before installing the Design EHD pis-ton rings or the Design EHT seal ring. Piston ring andseal ring installation instructions and valve body-to-bonnet reassembly instructions are presented in theTrim Replacement procedure.

Lapping SeatsA certain amount of leakage should be expected withmetal-to-metal seating in any valve. If the leakage be-comes excessive, however, the condition of the seat-ing surfaces of the valve plug (key 3) and seat ring(key 6) can be improved by lapping. (Deep nicksshould be machined out rather than ground out.) Usea good quality lapping compound with a mixture thatcontains 280 to 600 grit. Apply the compound to thebottom of the valve plug.

Use the following procedure to lap the seating sur-faces. Key numbers referenced in this procedure areshown in figure 14 for the Design EHD valve and infigure 15 for the Design EHT valve.

1. For all designs, install the seat ring gasket or O-ring (key 12), seat ring (key 6), seat ring cap screws(key 7), lower cage gasket (key 12), cage (key 2), andupper cage gasket (key 12) into the valve body per theinstructions in the Trim Replacement procedure.

2. Install the assembled valve plug and stem (keys 3and 4)—without piston rings or seal ring (key 8)—intothe cage.

3. For all seating surfaces, install the bonnet (key 1,figure 13) over the valve stem and secure the bonnetwith four of the hex nuts (key 14).

4. Attach a handle, such as a piece of strap iron se-cured by stem locknuts, to the valve plug stem. Rotatethe handle alternately in each direction to lap theseats.

Note

In order to preserve the effects of lap-ping, do not change either the positionof the seat ring in the valve body cavityor the position of the cage on the seatring after lapping the seating surfaces. Ifpossible, clean the parts without dis-turbing their positions. If the parts mustbe removed for cleaning, return them tothe original positions.

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, reas-semble the valve by following the numbered steps be-low. Be certain that all gasketed surfaces are clean.Key numbers referenced in this procedure are shownin figure 14 for the Design EHD valve and in figure 15for the Design EHT valve.

CAUTION

Thoroughly clean the seat ring (key 6),the seat ring cap screws (key 7), and thecap screw threads in the valve bodywith a good-quality degreaser. Unlessthe valve is to be used for oxygen ser-vice, thoroughly lubricate the cap screwthreads and the underside of the capscrew heads with one of the lubricants(or equivalent) shown in table 7.

Failure to lubricate as described maycause galling and improper seat ringgasket or O-ring (key 12) loading whichmay result in leakage.

WARNING

If the control valve is to be used for oxy-gen service, use the lubrication proce-dure above, but substitute a lubricantthat has been approved for oxygen ser-vice. Use of unapproved lubricantscreates a fire or explosion hazard.

1. Install either the seat ring gasket or the O-ring (key 12). Place the O-ring in the O-ring groove in theseat ring before installing the seat ring in the valve


11

body. Install the seat ring (key 6) and secure it with theseat ring cap screws (key 7). Torque the hex sockethead cap screws in a criss-cross pattern with no morethan 20 N�m (15 lbf�ft) of torque. When all are tight-ened to 20 N�m (15 lbf�ft), increase the torque 20 N�m(15 lbf�ft) without exceeding the torque value specifiedin table 7, and repeat the crisscross pattern. Repeatuntil all cap screws are tightened to the torque valuespecified in table 7. Repeat the final torque and if anycap screw still turns, tighten every cap screw again.

2. Install one of the cage gaskets (key 11) betweenthe valve body and cage (key 2), and install the cage.

3. If the cage used has multiple sizes of windows, at-tempt to orient the largest window toward the valvebody web (a shelf-like projection of the casting into theflow cavity). As an alternate reference, orient the larg-est window toward the process outlet for a flow-downand toward the process inlet for a flow-up valve.

4. Inspect the valve plug stem threads for any sharpedges that might cut the packing. Use a whetstone oremery cloth to smooth the threads if necessary.

5. To install the piston rings or seal ring (key 8), pro-ceed as appropriate:

For a Design EHD valve, if installing a new pistonring, the replacement piston ring will arrive in onepiece. Use a vise with smooth or taped jaws to breakthis replacement piston ring into halves. Place the newring in the vise so that the jaws compress the ring intoan oval. Slowly compress the ring until the ring snapson both sides. If one side snaps first, do not try to tearor cut the other side. Instead, keep compressing untilthe other side snaps.

Remove any protective tape or covering from thevalve plug and stem assembly, and set it on a protec-tive surface. Then place the piston ring in the pistonring groove with the fractured ends matched.

For a Design EHT valve, install the seal ring (key 8)onto the valve plug (key 3). Install the ring with theopen side facing the seat ring end of the valve plug fora flow-down application (view B of figure 15) or withthe open side facing the valve stem end of the valveplug for a flow-up application. Slide the backup ring(key 9) onto the valve plug. Secure with the retainingring (key 10). For a Design EHT valve with a WhisperTrim Level D cage, install the piston ring (key 30, fig-ure 15) using the procedure given in the Design EHDinstructions immediately preceding this paragraph.

6. Install the valve plug into the cage.

7. Install the other cage gasket (key 11) between thecage and the bonnet.

CAUTION

Failure to comply with good bonnet-to-body bolting practices and the torquevalues shown in table 6 may result incage crushing, cage diameter reduction,and/or bonnet deformation. Cheaterbars or slug wrenches should not beused for this procedure.

Hot torquing is not recommended.

8. Install the bonnet over the valve stem and onto thevalve body. Lubricate the threads of the studs (key 13)and the faces of the hex nuts (key 14) with Never-Seez Pure Nickel Special lubricant or equivalent (key 24). Secure the bonnet with hex nuts (key 14)and washers (key 29). Torque the nuts in a crisscrosspattern to no more than 1/4 of the nominal torque val-ue specified in table 6. When all nuts are tightened tothat torque value, increase the torque by 1/4 of thespecified torque value and repeat the crisscross pat-tern. Repeat this procedure until all nuts are tightenedto the specified nominal value. Repeat the final torquevalue and if any nut still turns, tighten every nut again.

9. Install new packing and the metal packing boxparts according to the appropriate arrangement in figure 6. Slip a smooth-edged pipe over the valvestem, and gently tamp each soft packing part into thepacking box.

10. Slide the packing follower, wiper, and packingflange into position. Lubricate the packing flange studs(key 4) and the faces of the packing flange nuts (key 5) and then install the packing flange nuts.

For spring-loaded PTFE V-ring packing: Tightenthe packing flange nuts until the shoulder on the pack-ing follower (key 13) contacts the bonnet (key 1).

For other kinds of packing, except ENVIRO-SEALand HIGH-SEAL: Tighten the packing flange nuts tothe maximum recommended torque shown in table 5.Then, loosen the packing flange nuts and retightenthem to the recommended minimum torque in table 5.

For ENVIRO-SEAL and HIGH-SEAL packing: Seethe Fisher Controls instruction manuals titledENVIRO-SEAL Packing System for Sliding-StemValves or HIGH-SEAL Live-Loaded Packing System(as appropriate) for packing instructions.

11. Mount the actuator by following the ActuatorMounting procedure. Check for packing leakage as thevalve is being put into service. Retorque the packingflange nuts as required (see table 5). Then, retightenthe hex nuts (key 14) to the torque shown in table 6.

CAUTION

Do not remove the existing valve stemfrom the valve plug unless you are plan-ning to replace the valve stem.

Never reuse an old valve stem with anew plug or reinstall a valve stem after ithas been removed. Replacing a valvestem requires drilling a new pin hole inthe stem. This drilling weakens the stemand may cause failure in service. How-ever, a used valve plug may be reusedwith a new valve stem.

9. Remove the existing valve stem and plug, cage,and seat ring from the valve body following the ap-propriate instructions in the Trim Removal section ofthis manual.

10. Replace all gaskets according to appropriateinstructions in the Trim Replacement section of thismanual.

CAUTION

To avoid excessive leakage and seaterosion, the valve plug must be initiallyseated with sufficient force to overcomethe resistance of the C-seal plug sealand contact the seat ring. You can cor-rectly seat the valve plug by using thesame force calculated for full load whensizing your actuator. With no pressuredrop across the valve, this force will ad-equately drive the valve plug to the seatring, thus giving the C-seal plug seal apredetermined permanent set. Once thisis done, the plug/retainer assembly, thecage, and the seat ring become amatched set.

With full actuator force applied and thevalve plug fully seated, align the actua-tor travel indicator scale with the lowerend of valve travel. Refer to the ap-propriate actuator instruction manualfor information on this procedure.

To avoid leakage when the valve is re-turned to service, use appropriate meth-ods and materials to protect all sealingsurfaces of the trim parts during mainte-nance.

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 after ithas been removed. Replacing a valvestem requires drilling a new pin hole inthe stem. This drilling weakens the stemand may cause failure in service. How-ever, a used valve plug may be reusedwith 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 Trim Re-moval section of this manual.

3. Locate the staked thread on top of the valve plug(figure 9). The staked thread secures the retainer. Usea drill with a 1/8-inch bit to drill out the staked area ofthe thread. Drill approximately 1/8-inch into the metalto remove the staking.

4. Locate the break between sections of the pistonring(s). Using an appropriate tool such as a flat-bladescrewdriver, carefully pry out the piston ring(s) fromthe 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-blade screw-driver to pry the C-seal plug seal off the plug. Use cau-tion to avoid scratches or other damage to the sealingsurfaces where the C-seal plug seal makes contactwith the valve plug (figure 11).

8. Inspect the lower seating surface where the valveplug contacts the seat ring for wear or damage whichwould prevent proper operation of the valve. Also, in-spect the upper seating surface inside the cage wherethe C-seal plug seal contacts the cage, and inspectthe sealing surface where the C-seal plug seal makescontact with the plug (figure 11).

9. Replace or repair trim parts according to the follow-ing procedure for lapping metal seats, remachiningmetal seats, or other valve plug maintenance proce-dures as appropriate.

Lapping Metal Seats (C-seal Constructions)Before installing a new C-seal plug seal, lap the lowerseating surface (valve plug to seat ring, figure 11) fol-lowing appropriate procedures in the Lapping Seatssection of this manual.

Remachining Metal Seats (C-seal Constructions)See figure 12. A valve plug with a C-seal metal plugseal features two seating surfaces. One seating sur-face is found where the valve plug contacts the seatring. The second seating surface is found where theC-seal plug seal contacts the upper seating surface inthe cage. If you machine the seats on the seat ringand/or plug, you must machine an equal dimensionfrom 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-seal Constructions)1. Apply a suitable high-temperature lubricant to theinside diameter of the C-seal plug seal. Also, lubricatethe outside diameter of the valve plug where the C-seal plug seal must be pressed into the proper seal-ing position (figure 7).

2. Orient the C-seal plug seal for correct sealing ac-tion based on the process fluid flow direction throughthe valve.

� The open interior of the C-seal plug seal mustface up in a valve with flow-up construction (figure 7).

NOTE:

� The open interior of the C-seal plug seal mustface down in a valve with flow-down construction (fig-ure 7).

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 Controls or atool could be manufactured followingthe dimensions given in Figure 8.

3. Place the C-seal plug seal over the top of the valveplug and press it onto the plug using the installationtool. Carefully press the C-seal plug seal onto the pluguntil the installation tool contacts the horizontal refer-ence surface of the valve plug (figure 10).

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 an ap-propriate tool such as a strap wrench.

5. Using an appropriate tool such as a center punch,stake the threads on top of the plug in one place (fig-ure 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/retainer assembly,and stem to the valve body and completely reas-semble the valve package following the appropriateinstructions in the Trim Replacement section of thismanual.

CAUTION

To avoid excessive leakage and seaterosion, the valve plug must be initiallyseated with sufficient force to overcomethe resistance of the C-seal plug sealand contact the seat ring. You can cor-rectly seat the valve plug by using thesame force calculated for full load whensizing your actuator. With no pressuredrop across the valve, this force will ad-equately drive the valve plug to the seatring, thus giving the C-seal plug seal apredetermined permanent set. Once thisis done, the plug/retainer assembly, thecage, and the seat ring become amatched set.

With full actuator force applied and thevalve plug fully seated, align the actua-tor travel indicator scale with the lowerend of valve travel. Refer to the ap-propriate actuator instruction manualfor information on this procedure.

Actuator MountingThe following procedure assumes that the valve andactuator are fully assembled, but with the actuator re-moved from the valve. Unless otherwise identified, theparts involved in making up the actuator-valve stemconnection are shown in figure 5.

CAUTION

Never use a wrench or pliers on thevalve plug stem and never turn the valveplug stem while the valve plug assemblyis seated. A damaged stem could cut thepacking and allow leakage. Turning theplug while seated could damage theseats allowing leakage at shutoff.

1. Turn the stem locknuts onto the valve stem.

2. Move the valve plug to the closed position.


17

3. Place the actuator on the bonnet and secure withthe hex nuts (key 26, figure 13). Connect supply pres-sure to the actuator.

4. Make sure the actuator stem is fully retracted. Witha properly assembled direct-acting spring-return ac-tuator, spring compression forces the actuator stem tothe fully retracted position. A double-acting piston ac-tuator or a reverse-acting spring-return actuator re-quires air pressure (or a side-mounted handwheel) tostroke the actuator stem to the fully retracted position.

5. Extend the actuator stem a distance equal to thetravel (as specified on the nameplate).

6. Attach both halves of the stem connector, makingsure the connector fully engages both the actuatorthreads and valve plug stem threads. Install the capscrews in the stem connector, but tighten them onlyslightly at this time.

7. Stroke the valve to the fully open position. Thetravel indicator should show the valve to be wide open.If it does not, loosen the screws that hold the travelindicator scale, and shift the scale to the required posi-tion.

8. Stroke the valve to the closed position. The travelindicator should show the valve to be closed.

9. If travel is not correct, lift the valve plug assembly(key 3, figure 14 or 15) off its seat approximately 6.4

mm (1/4 inch) and screw the valve plug stem into orout of the stem connector as follows. To lengthen trav-el, turn the valve plug stem into the stem connectorslightly. To shorten travel, turn the valve plug stem outof the stem connector slightly. (Turning it out too farwill limit the stroke.)

10. After adjusting the stem connection so that theactuator will properly stroke the valve plug assembly,tighten the cap screws in the stem connector, tighten-ing the one opposite the anti-rotation groove first.Then lock the stem locknuts against the stem connec-tor.

Parts OrderingEach valve is assigned a serial number, which can befound on the valve body. This same number also ap-pears on the actuator nameplate when the valve isshipped from the factory as part of a control valve as-sembly. Refer to the number when contacting yourFisher Controls sales office or sales representative fortechnical assistance or when ordering replacementparts.

When ordering replacement parts, also be sure to in-clude the 11-character part number for each part re-quired from the following parts list.
