Installation

WARNING

Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal
injury.

Personal injury or equipment damage caused by sudden release of pressure may result if the valve assembly is installed
where service conditions could exceed the limits given in table 1 or on the appropriate nameplates. To avoid such injury or
damage, provide a relief valve for over-pressure protection as required by government or accepted industry codes and
good engineering practices.

Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.

If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.

CAUTION

When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Responsibility for the safety of process media and compatibility of valve
materials with process media rests solely with the purchaser and end-user. Since some valve body/trim material
combinations are limited in their pressure drop and temperature ranges, do not apply any other conditions to the valve
without first contacting your Emerson Process Management sales office.

Before installing the valve, inspect the valve and pipelines for any damage and any foreign material which may cause
product damage.

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

2. Make certain the valve body interior is clean, that pipelines are free of foreign material, and that the valve is
orientedsothatpipelineflowisinthesamedirectionasthearrowonthesideofthevalve.

D100398X012

3. The control valve assembly may be installed in any orientation unless limited by seismic criteria. Howev er, the
normal method is with the actuator vertical above the valve. Other positions may result in uneven valve plug and
cage wear, and improper operation. With some valv es, the actuator may also need to be supported when it is not
vertical. For more information, consult your Emerson Process Management sales office.

4. Use accepted piping and welding practices when installing the valve in the line. For flanged valves, use a suitable
gasket between the valve and pipeline flanges.

CAUTION

Depending on valve body materials used, post weld heat treating may be required. If so, damage to internal elastomeric
and plastic parts, as well as internal metal parts is possible. Shrink-fit pieces and threaded connections may also loosen. In
general, if post weld heat treating is to be performed, all trim parts should be removed. Contact your Emerson Process
Management sales office for additional information.

5. With a leak-off bonnet construction, remove the pipe plugs (keys 14 and 16, figure 14) to hook up the leak-off
piping. If continuous operation is required during inspection or maintenance, install a three-valve bypass around
the control valve assembly.

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

WARNING

Personal injury could result from packing leakage. Valve packing was tightened prior to shipment; however, the packing
might require some readjustment to meet specific service conditions. Check with your process or safety engineer for any
additional measures that must be taken to protect against process media.

Valves with ENVIRO-SEAL live-loaded packing or HIGH-SEAL live-loaded packing will not require this initial
readjustment. See the Fisher instruction manuals, ENVIRO-SEAL Packing System for Sliding-Stem Valves or HIGH-SEAL
Live-Loaded Packing System (as appropriate), for packing instructions. If you wish to convert your present packing
arrangement to ENVIRO-SEAL packing, refer to the retrofit kits listed in the Parts Kits section.

Maintenance

Valve parts are subject to normal wear and must be inspected and replaced as necessary. Inspection and maintenance
frequency depends on the severity of service conditions. This section includes instructions for packing lubrication,
packing maintenance, trim maintenance, and ENVIRO-SEAL bellows seal bonnet replacement. All maintenance
operations may be performed with the valve in the line.

WARNING

Avoid personal injury or property damage from sudden release of process pressure or bursting of parts. Before performing
any maintenance operations:

D Do not remove the actuator from the valve while the valve is still pressurized.

D Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal

injury.

D Disconnect any operating lines providing air pressure, electric power, or a control signal to the actuator. Be sure the

actuator cannot suddenly open or close the valve.

4

Instruction Manual

D100398X012

D Use bypass valves or completely shut off the process to isolate the valve from process pressure. Relieve process pressure

from both sides of the valve. Drain the process media from both sides of the valve.

D Vent the pneumatic actuator loading pressure and relieve any actuator spring precompression.
D Use lock-out procedures to be sure that the above measures stay in effect while you work on the equipment.
D The valve packing box may contain process fluids that are pressurized, even when the valve has been removed from the

pipeline. Process fluids may spray out under pressure when removing the packing hardware or packing rings, or when
loosening the packing box pipe plug.

D Check with your process or safety engineer for any additional measures that must be taken to protect against process

media.

CAUTION

Follow instructions carefully to avoid damaging the product surfaces, which could result in damage to the product.

Note

Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket during reassembly. This ensures a
good gasket seal because the used gasket may not seal properly.

Packing Lubrication

Note

ENVIRO-SEAL and HIGH-SEAL packing do not require lubrication.

WARNING

To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen
service or in processes with temperatures over 260_C (500_F).

If a lubricator or lubricator/isolating valve (figure 2) is provided for PTFE/composition or other packings that require
lubrication, it will be installed in place of the pipe plug (key 14, figure 14). Use a good quality silicon-base lubricant. Do
not lubricate packing used in oxygen service or in processes with temperatures over 260_C(500_F). To operate the
lubricator, simply turn the cap screw clockwise to force the lubricant into the packing box. The lubricator/isolating
valve operates the same way except open the isolating valve before turning the cap screw and then close the isolating
valve after lubrication is completed.

Packing Maintenance

Note

For valves with ENVIRO-SEAL packing, see the Fisher instruction manual, ENVIRO-SEAL Packing System for Sliding-Stem Valves,
D101642X012, for packing instructions.

ET Valve

October 2014

For valves with HIGH-SEAL packing, see the Fisher instruction manual, HIGH-SEAL Live-Loaded Packing System, D101453X012, for
packing instructions.

Instruction Manual

D100398X012

Key numbers refer to figure 3 for PTFE V-ring packing and to figure 4 for PTFE/composition packing, unless otherwise
indicated.

For spring-loaded single PTFE V-ring packing, the spring (key 8) maintains a sealing force on t he packing. If leakage is
noted around the packing follower (key 13), check to be sure the shoulder on the packing follower is touching the
bonnet. If the shoulder is not touching the bonnet, tighten the packing flange nuts (key 5, figure 14) until the shoulder
is against the bonnet. If leakage cannot be stopped in this manner, proceed to the Replacing Packing procedure.

Figure 2. Lubricator and Lubricator/Isolating Valve (Optional)

LUBRICATOR

10A9421-A
AJ5428-D
A0832-2

LUBRICATOR/ISOLATING VALVE

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

If the packing is relatively new and tight on the stem, and if tightening the packing flange nuts does not stop the
leakage, the valve stem may be worn or nicked so that a seal cannot be made. The surface finish of a new valve stem is
critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, the leakage
may be caused by nicks or scratches around the packing box wall. If performing any of the following procedures,
inspect the valve stem and packing box wall for nicks and scratches.

Replacing Packing

WARNING

Refer to the WARNING at the beginning of the Maintenance section in this instruction manual.

1. Isolatethecontrolvalvefromthelinepressure,releasepressure from both sides of the valve, and drain the process
media from both sides of the valve. If using a power actuator, also shut off all pressure lines to the power actuator,
andreleaseallpressurefromtheactuator.Uselock-outprocedurestobesurethattheabovemeasuresstayin
effect while you work on the equipment.

2. Disconnect the operating lines from the actuator and any leak-off piping from the bonnet. Disconnect the stem
connector, then remove the actuator from the valve by unscrewing the yoke locknut (key 15, figure 14) or the hex
nuts (key 26, figure 14).

3. Loosen the packing flange nuts (key 5, figure 14) so that the packing is not tight on the valve stem. Remove any
travel indicator parts and stem locknuts from the valve stem threads.

WARNING

To avoid personal injury or property damage caused by uncontrolled movement of the bonnet, loosen the bonnet by
following the instructions in the next step. Do not remove a stuck bonnet by pulling on it with equipment that can stretch
or store energy in any other manner. The sudden release of stored energy can cause uncontrolled movement of the bonnet.

CAUTION

Avoid damaging the seating surface caused by the valve plug and stem assembly dropping from the bonnet (key 1, figure

14) after being lifted part way out. When lifting the bonnet, temporarily install a valve stem locknut on the valve stem. The
locknut will prevent the valve plug and stem assembly from dropping out of the bonnet.

4. Hex nuts (key 16, figure 16, 17, or 20) or cap screws (not shown) attach the bonnet (key 1, figure 14) to the valve
body (key 1, figure 16, 17, or 20). Loosen these nuts or cap screws approximately 3 mm (1/8 inch). Then loosen the
body-to-bonnet gasketed joint by either rocking the bonnet or prying between the bonnet and valve. Work the

5. Remove the locknut and separate the valve plug and stem from the bonnet. Set the parts on a protective surface to
prevent damage to gasket or seating surfaces.

CAUTION

To prevent possible product damage, cover the opening in the valve in the following procedure to prevent foreign material
from getting into the valve body cavity.

6. Remove the bonnet gasket (key 10, figure 16, 17, or 20) and cover the opening in the valve to protect the gasket
surface and prevent foreign material from getting into the valve body cavity.

7. Remove the packing flange nuts, packing flange, upper wiper, and packing follower (keys 5, 3, 12, and 13, figure

14). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or
other tool that will not scratch the packing box wall. Clean the packing box and the metal packing parts.

8. Inspect the valve stem threads and packing box surfaces for any sharp edges which might cut the packing.
Scratches or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot
be improved by light sanding, replace the damaged parts by following the appropriate steps in the Trim
Maintenance procedure.

9. Remove the covering protecting the valve body cavity and install a new bonnet gasket (key 10, figure 16, 17, or 20),
making sure the gasket seating surfaces are clean and smooth. Then slide the bonnet over the stem and onto the
stud bolts (key 15, figure 16, 17, or 20) or onto the valve body cavity if cap screws (not shown) will be used instead.

Note

Proper performance of the bolting procedures in step 10 compresses the spiral wound gasket (key 12, figure 16 or 17) or load ring
(key 26, figure 20) enough to both load and seal the seat ring gasket (key 13, figure 16, 17 or 20). It also compresses the outer
edge of the bonnet gasket (key 10, figure 16 through 20) enough to seal the body-to-bonnet joint.

The proper bolting procedures in step 10 include--but are not limited to--ensuring that bolting threads are clean, and evenly
tightening the cap screws, or the nuts onto the studs, in a crisscross pattern. Tightening one cap screw or nut may loosen an
adjacent cap screw or nut. Repeat the crisscross tightening pattern several times until each cap screw or nut is tight and the
body-to-bonnet seal is made. When the operating temperature has been reached, perform this torquing procedure once again.

WARNING

To avoid personal injury due to leaking fluid, avoid damaging gasket sealing surfaces. The surface finish of the valve stem
(key 7) is critical for making a good packing seal. The inside surface of the cage or cage/baffle assembly (key 3), or cage
retainer (key 31), is critical for smooth operation of the valve plug. The seating surfaces of the valve plug (key 2) and seat
ring (key 9) are critical for proper shutoff. Unless inspection reveals otherwise, assume all these parts are in good condition
and protect them accordingly.

2. Remove the packing flange nuts, packing flange, upper wiper, and packing follower (keys 5, 3, 12, and 13 in figure

14). Carefully push out all the remaining packing parts from the valve side of the bonnet using a rounded rod or
other tool that will not scratch the packing box wall. Clean the packing box and the metal packing parts.

3. Inspect the valve stem threads and packing box surfaces for any sharp edges which might cut the packing.
Scratches or burrs could cause packing box leakage or damage to the new packing. If the surface condition cannot
be improved by light sanding, replace the damaged parts.

4. Remove the load ring (key 26) from an NPS 8 ET valve, or the cage adaptor (key 4) from any restricted-trim valve
throughNPS4,andwrapitforprotection.

5. On an NPS 6 ET valve with Whisper Trim III or WhisperFlo cage, also remove the bonnet spacer (key 32) and bonnet
gasket (key 10) on top of the spacer. Then on any construction with a cage retainer (key 31), remove the cage
retainer and its associated gaskets. A Whisper Trim III and WhisperFlo cage retainer has two 3/8-inch-16 UNC
tappings in which screws or bolts can be installed for lifting.

6. Remove the cage or cage/baffle assembly (key 3), the associated gaskets (keys 10, 11, and 12), and shim (key 51). If
thecageisstuckinthevalve,usearubbermallettostriketheexposedportionofthecageatseveralpointsaround
its circumference.

7. For constructions other than TSO (tight shutoff) trim, remove the seat ring or liner (key 9) or disk seat (key 22), seat
ring gasket (key 13), and the seat ring adaptor (key 5) and adaptor gasket (key 14) where used in a restricted-trim
seat ring construction. PTFE-seat constructions use a disk (key 23) sandwiched between the disk seat and disk
retainer (key 21).

8. For TSO (tight shutoff) trim constructions, perform the following steps (refer to figures 6 and 7):

D Remove the retainer, backup ring, anti-extrusion rings, and piston ring.

D Remove the set screws that lock the outer plug to the inner plug.

D Using a strap wrench or similar tool, unscrew the outer plug from the inner plug. Do not damage the outer plug

guide surfaces.

D Remove the protected soft seat seal.

D Inspect the parts for damage and replace if needed.

9. For all constructions, inspect parts for wear or damage which would prevent proper operation of the valve. Replace
or repair trim parts according to the following procedure for Lapping Metal Seats or other valve plug maintenance
procedures as appropriate.

Lapping Metal Seats

CAUTION

To avoid damaging the ENVIRO-SEAL Bellows Seal Bonnet assembly, do not attempt to lap the metal seating surfaces. The
design of the assembly prevents rotation of the stem and any forced lapping rotation will damage internal components of
the ENVIRO-SEAL Bellows Seal bonnet.

Except with respect to the ENVIRO-SEAL Bellows Seal Bonnet assembly, with metal-seat constructions, lapping seating
surfaces of the valve plug and seat ring or liner (keys 2 and 9, figure 16, 17, or 20) can improve shutoff. (Deep nicks
should be machined out rather than ground out.) Use a good quality l apping compound of a mixture of 280 to
600-grit. Apply the compound to the bottom of the valve plug.

Assemble the valve to the extent that the cage and the cage retainer and bonnet spacer (if used) are in place and the
bonnetisboltedtothevalvebody.Asimplehandlecanbemadefromapieceofstrapironlockedtothevalveplug
stem with nuts. Rotate the handle alternately in each direction to lap the seats. After lapping, remove the bonnet and
clean the seat surfaces. Completely assemble as described in the Assembly portion of the Trim Maintenance procedure
and test the valve for shutoff. Repeat the lapping procedure if leakage is still excessive.

and the NPS 8 ET valve.

CAUTION

To avoid the valve plug seal ring (key 28) not sealing properly, be careful not to scratch the surfaces of the ring groove in
the valve plug or any of the surfaces of the replacement ring.

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

Instruction Manual

D100398X012

For the two-piece seal ring, The ring cannot be reused because it is a closed ring which must be pried and/or cut from
the groove. Once the seal ring is removed, the elastomeric backup ring (key 29), which is also a closed ring, can be
pried from the groove.

CAUTION

To avoid damaging the seal ring, slowly and gently stretch it for the following procedure. Avoid jerking sharply on t he ring.

To install a new two-piece seal ring, apply a general purpose silicone-base lubricant to both the backup ring and seal
ring(keys29and28).Placethebackupringoverthestem(key7)andintothegroove.Placethesealringoverthetop
edge of the valve plug (key 2) so that it enters the groove on one side of the valve plug. Slowly and gently stretch the
sealringandworkitoverthetopedgeofthevalveplug.ThePTFEmaterialinthesealringmustbepermittedtimeto
cold-flow during the stretching procedure, so avoid jerking sharply on this ring. Stretching the seal ring over the valve
plug may make it seem unduly loose when in the groove, but it will contract to its original size after insertion into the
cage.

For the spring-loaded seal ring, the ring used on a valve plug having a 136.5 mm (5.375 inch) or less port diameter may
be removed undamaged by first working the retaining ring (key 27) off with a screwdriver. Then carefully slide the
metal backup ring (key 29) and seal ring (key 28) off the valve plug (key 2). The spring-loaded seal ring used on a valve
plug having a 178 mm (7-inch) or greater port diameter must be carefully pried and/or cut from its groove. Therefore,
it cannot be reused.

A spring-loaded seal ring must be installed so that its open side faces toward the valve stem, or toward the seat of the
plug depending on flow direction, as shown in view A of figure 16 or 20. To install a spring-loaded seal ring on a valve
plug with a 136.5 mm (5.375 inch) or less port diameter, slide the seal ring (key 28) onto the valve plug followed by
the metal backup ring (key 29). Then install the retaining ring (key 27) by inserting one end in the groove and, while
turning the plug, press the ring into the groove. Again, be careful not to scratch any surfaces of the ring or plug.

CAUTION

To avoid damaging the seal ring, slowly and gently stretch it for the following procedure. Avoid jerking sharply on t he ring.

To install the seal ring on a valve plug with 178 mm (7-inch) or greater port diameter, lubricate it with a general
purpose silicone-base lubricant. Then gently stretch the seal ring and work it over the top edge of the valve plug. The
PTFE material in the seal ring must be permitted time to cold-flow during the stretching procedure, so avoid jerking
sharply on the ring. Stretching the seal ring over the valve plug may make it seem unduly loose when in the groove,
but it will contract to its original size after insertion into the cage.

CAUTION

Never reuse an old stem or adaptor with a new valve plug. Using an old stem or adaptor with a new plug requires drilling a
new pin hole in the stem (or adaptor, in case an ENVIRO-SEAL bellows seal bonnet is being used). This drilling weakens the
stem or adaptor and may cause failure in service. However, a used valve plug may be reused with a new stem or adaptor,
except with Cavitrol III trim.

Note

The valve plug and valve plug stem for 2-stage Cavitrol III trim are a matched set and must be ordered together. If the 2-stage
Cavitrol III valve plug or valve plug stem is damaged, replace the entire assembly (key 2, figure 20).

Assembly

Except where indicated, key numbers are referenced in figure 16 for standard NPS 1 through 6 constructions, figure 17
for Whisper Trim III detail, figures 18 and 19 for WhisperFlo detail, and figure 20 for Cavitrol III detail and the NPS 8 ET
valve.

1. With a restricted-trim seat ring construction, install the adaptor gasket (key 14) and seat ring adaptor (key 5).

2. Install the seat ring gasket (key 13), seat ring or liner (key 9), or disk seat (key 22). With a PTFE-seat construction,
install the disk and disk retainer (keys 21 and 23).

3. Install the cage or cage/baffle assembly (key 3). Any rotational orientation of the cage or assembly with respect to
the valve body is acceptable. A Whisper Trim III cage designated by level A3, B3, or C3 may be installed with either
end up. The level D3 cage/baffle assembly or Cavitrol III cage assembly, however, must be installed with the hole
pattern end next to the seat ring. If a cage retainer (key 31) is to be used, place it on top o f the cage.

4. For constructions other than TSO (tight shutoff) trim, slide the valve plug (key 2) and stem assembly, or valve plug
and ENVIRO-SEAL bellows seal assembly, into the cage. Make sure the seal ring (key 28) is evenly engaged in the
entrance chamfer at the top of the cage (key 3) or cage retainer (key 31) to avoid damaging the ring.

5. For TSO (tight shutoff) trim constructions, perform the following steps (refer to figures 6 and 7).

D Thread the outer plug onto the inner plug until the parts seat metal to metal, using a strap wrench or similar tool

that will not damage the outer plug guide surfaces.

D Mark the top of the inner plug and outer plug with alignment marks in the assembled position.

D Disassemble the outer plug from the inner plug and install the seal over the inner plug, so that the seal rests below

the threaded area.

D Thread the outer plug onto the inner plug and tighten with a strap wrench or similar tool until the alignment marks

line up. This will ensure that the plug parts are metal to metal and the seal is compressed properly. Do not damage
the outer plug guide surfaces.

D Install set screws centering the inner plug in the outer plug and torque to 11 NSm(8lbfSft).

D Assemble the piston ring, anti-extrusion rings, backup ring, and retainer.

6. For all constructions, place the gaskets (keys 12, 11 or 14 if used, and 10) and the shim (key 51) on top of the cage
or cage retainer. If there is a cage adaptor (key 4) or a bonnet spacer (key 32), set it on the cage or cage retainer
gaskets and place another flat sheet gasket (key 10) on top of the adaptor or spacer. If there is only a cage retainer,
place another flat sheet gasket on the retainer.

7. With an NPS 8 ET valve, install the load ring (key 26).
