Instruction Manual
D104208X012
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.
WARNING
When ordered, the valve configuration and construction materials were selected to meet particular pressure, temperature,
pressure drop, and controlled fluid conditions. Because 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 sales office
.
WARNING
Some bonnet flanges have a tapped hole that was used to handle the bonnet during manufacture. Do not use this tapped
hole to lift the valve assembly or personal injury may result.
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 the valve is oriented so
that pipeline flow is in the same direction as the arrow on the side of the valve.
Note
NPS 8 to 12 CL900 and CL1500 HPT-C valves contain a flow vane in the lower flow passage. This is critical to proper function of the
valve and is not a defect.
3. Gas Service: The normal method of mounting for gas service is with the actuator vertical above the valve body.
However, the control valve assembly may be installed in any orientation unless limited by seismic criteria. Other
positions may result in uneven valve plug and cage wear that could result in improper operation. For mounting
assistance, consult your Emerson sales office
.
CAUTION
To avoid possible damage to the packing, do not allow the installed actuator angle to be so flat as to allow liquid inside the
bonnet to come in contact with the packing.
Also, if insulation is applied, do not let the insulation run up the extension bonnet. This could cause the packing to freeze
and be damaged.

Instruction Manual
D104208X012
HPS-C and HPT-C Valves
September 2020
Liquid Service: The preferred method of mounting for liquid service is with the actuator vertical above the valve body.
This will allow a vapor layer to form between the liquid and the packing. If there are piping constraints, the actuator
can be angled slightly from vertical. However, in no case should the angle be so flat as to allow liquid inside the bonnet
to come in contact with the packing. For mounting assistance, consult your Emerson sales office.
4. If insulation is applied, make sure it is applied only to the body/bonnet joint. Do not let the insulation run up the
extension bonnet.
5. Use accepted piping and welding practices when installing the valve in the line. For flanged valve bodies, use a
suitable gasket between the valve body and pipeline flanges.
6. If the actuator and valve are shipped separately, refer to the actuator mounting procedure in the appropriate
actuator instruction manual.
7. If the valve body was shipped without packing installed in the packing box, install the packing before putting the
valve body into service. Refer to instructions given in the Packing Maintenance procedure.
WARNING
Personal injury could result from packing leakage. Valve packing was tightened before shipment; however, the packing
might require some readjustment to meet specific service conditions.
Valves with ENVIRO‐SEAL™ live‐loaded packing will not require this initial readjustment. See the Fisher instruction
manual ENVIRO‐SEAL Packing System for Sliding‐Stem Valves (D101642X012
convert your present packing arrangement to ENVIRO‐SEAL packing, refer to the retrofit kits listed in the parts kit
sub‐section near the end of this manual.
) for packing instructions. If you wish to
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 maintenance
and trim maintenance. 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. 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.
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.

Instruction Manual
D104208X012
CAUTION
Follow instructions carefully to avoid damaging the product surfaces, which could result in damage to the product.
Note
The HPS-C/HPT-C valves use spiral-wound gaskets which are crushed to provide their seal. A spiral-wound gasket should never be
reused. Whenever a gasket seal is disturbed by removing or shifting parts, a new gasket should be installed upon reassembly. This
is necessary to ensure a good gasket seal because the used gasket may not seal properly.
Packing Maintenance
This section covers PTFE V‐ring, double PTFE, and graphite packing used in extension bonnets (figure 2).
Note
If the valve has ENVIRO‐SEAL live‐loaded packing installed, refer to the instruction manual ENVIRO‐SEAL Packing System for Sliding
Stem Valves (D101642X012
) for packing instructions. Figure 4 shows typical ENVIRO‐SEAL arrangements.
Standard packing key numbers are shown in figure 2. ENVIRO-SEAL packing key numbers are shown in figure 4. Bonnet
and valve key numbers are shown in figures 5, 6, and 7.
For spring-loaded single PTFE V-ring packing, the spring (key 24) maintains a sealing force on the packing. If leakage is
noted around the packing follower (key 28), 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 20), until the shoulder is
against the bonnet. If leakage cannot be stopped in this manner, proceed with replacing packing procedures.
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, it is possible that the valve stem is 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, it
is possible that the leakage is 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. If leakage continues,
replace the packing by following the numbered steps presented in the replacing packing procedure.
Adding Packing Rings
Key numbers referred to in this procedure are shown in figures 2, 5, and 6 unless otherwise noted.
When using packing with a lantern ring (key 24) it may be possible to add packing rings above the lantern ring as a
temporary measure without removing the actuator from the valve body.
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 the valve. If using a power actuator, also shut‐off all pressure lines to the power
actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in
effect while you work on the equipment.
2. Remove the packing flange nuts (key 20) and lift the packing flange, upper wiper, and packing follower (keys 18, 27,
and 28) away from the valve body.

3. It may be possible to dig out the old packing rings on top of the lantern ring, but use care to avoid scratching the
valve plug stem or packing box wall. Clean all metal parts to remove particles that would prevent the packing from
sealing.
4. Remove the stem connector and slip the packing rings over the end of the valve plug stem.
5. Reassemble the packing follower, upper wiper, packing flange, and packing flange nuts (keys 28, 27, 18, and 20).
6. Reconnect the body‐actuator stem connection according to the appropriate actuator instruction manual.
7. Tighten the packing flange nuts only far enough to stop leakage under operating conditions. Check for leakage
around the packing follower when the valve is being put into service. Retighten the packing flange nuts as required
(see table 3).

WARNING
Refer to the warning at the beginning of the Maintenance section in this instruction manual.
Key numbers and sequence of assembly of packing parts are shown in figure 2. Bonnet and valve key number locations
are shown in figures 5, 6, and 7, unless otherwise noted.
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 the valve. If using a power actuator, also shut‐off all pressure lines to the power
actuator, release all pressure from the actuator. Use lock‐out procedures to be sure that the above measures stay in
effect while you work on the equipment. Observe the warnings at the start of the Maintenance section.
2. Disconnect the operating lines from the actuator and any leak-off piping from the bonnet. Disconnect the stem
connector and remove the actuator from the valve by unscrewing the yoke locknut (key 32) or hex nuts (key 30).
3. Loosen the packing flange nuts (key 20) 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 steps.
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. If the cage sticks to the bonnet, proceed
carefully with bonnet removal and support the cage so that it will not fall unexpectedly from the bonnet.
4. When lifting the bonnet, be sure the plug and stem assembly (key 4 and 5), cage (key 2), and cage retainer (key 45),
if applicable, remain in the valve body. This avoids damage to the seating surfaces as a result of the assembly
dropping from the bonnet after being lifted part way out. The parts are also easier to handle separately.
WARNING
To avoid possible personal injury, review your process shutdown procedures to be sure process pressure is not applied to
the valve for the following procedure.
5. Hex nuts (key 13) attach the bonnet to the valve body (key 1). Loosen these nuts or cap screws approximately 3 mm
(1/8 inch). Then, loosen the body-to-bonnet joint by either rocking the bonnet or prying between the bonnet and
valve body. Work with a prying tool around the bonnet until the bonnet loosens.
D If fluid leaks from the joint, it may indicate that process pressure is applied to the valve. Review your process
shutdown procedures, and be sure process pressure is not applied to the valve.
D If no fluid leaks from the joint, proceed to the next step.
6. Unscrew the hex nuts (key 13) and carefully lift the bonnet off the valve stem. If the valve plug and stem assembly
starts to lift with the bonnet, use a brass or lead hammer on the end of the stem and tap it back down. Set the
bonnet on a cardboard or wooden surface to prevent damage to the bonnet gasket surface.

2. Lubricate the stud threads and the faces of the hex nuts (key 13) with anti-seize lubricant (not necessary if new
factory pre lubricated hex nuts are used). Replace the hex nuts and tighten them finger-tight. Stroke the valve
several times to center the trim.
Torque the nuts in a crisscross pattern to no more than 1/4 of the nominal torque value specified in table 4. When
all nuts are tightened to that torque value, increase the torque by 1/4 of the specified nominal torque and repeat
the crisscross pattern. Repeat this procedure until all nuts are tightened to the specified nominal value. Apply the
final torque value again and, if any nut still turns, tighten every nut again
3. Install new packing and the metal packing box parts according to the appropriate arrangement in figure 2. Place a
smooth-edged pipe over the valve stem and gently tap each soft packing part into the packing box.
4. Slide the packing follower, upper wiper, and packing flange (keys 28, 27, and 18) into position. Lubricate the
packing flange studs (key 19) and faces of the packing flange nuts (key 20). Install the packing flange nuts.
5. Tightening packing flange nuts (key 20):
D For spring-loaded PTFE V-ring packing, tighten the packing flange nuts until the shoulder on the packing follower
(key 28) contacts the bonnet.
D For graphite packing, tighten the packing flange nuts to the maximum recommended torque shown in table 3.
Then, loosen the packing flange nuts, and retighten them to the recommended minimum torque shown in
table 3.
D For other packing types, tighten the packing flange nuts alternately in small equal increments until one of the nuts
reaches the minimum recommended torque shown in table 3. Then, tighten the remaining nut until the packing
flange is level and at a 90 degree angle to the valve stem.
D For ENVIRO-SEAL live-loaded packing; refer to the Fisher instruction manual ENVIRO-SEAL Packing System for
Sliding-Stem Valves (D101642X012

Note
The cage and cage retainer lifting holes are provided for ease of disassembly. To prevent damage to the cage lifting hole, fully
engage the threaded rod into the cage hole, but do not overtighten the hoist rod. It only needs to be hand tight.
If it is hard to lift the cage, a piece of wood and a hammer can be used to strike on the top chamfer of the cage to loosen it from the
body or seat ring gasket.
ASTM A193 B7 or comparable threaded rods are required for cage removal. Contact your Emerson sales office
information.

Valve Plug Maintenance
CAUTION
To avoid the valve plug seal ring (key 7) not sealing properly and affecting valve performance, be careful not to scratch the
surfaces of the ring groove on the valve plug or any of the surfaces of the replacement ring.
1. With the valve plug (key 4) removed, according to the disassembly portion of the Trim Maintenance procedure,
proceed as follows: For HPS-C valves, proceed to step 5:
2. For HPT-C valves, the spring-loaded seal ring may be removed by first working the retaining ring (key 9) off with a
screwdriver. Then carefully slide the metal backup ring (key 8) and seal ring (key 7) off the valve plug (key 4).
3. 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. To install a spring-loaded seal ring, slide the seal ring (key 7) onto the valve
plug followed by the metal backup ring (key 8).
4. Then install the retaining ring (key 9) 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 weakening the stem that may cause failure in service, never reuse an old stem with a new valve plug. Using an old
stem with a new plug requires drilling a new pin hole in the stem, which will weaken the stem. However, a used valve plug
may be reused with a new stem.
5. To replace the valve stem (key 5), drive or drill out the pin (key 6). Unscrew the valve plug from the stem.
6. Screw the new stem into the valve plug. Tighten to the torque value given in table 5. Also, use this table to select
the proper drill size. Drill through the stem using the hole in the valve plug as a guide. Remove any chips or burrs
and drive in a new pin to lock the assembly.
Trim Assembly NPS 1 through 6
Key number locations are shown in figure 5 and 6, unless otherwise noted.
1. Install the seat ring gasket (key 11), and seat ring (key 3).
2. Install the cage (key 2). Any rotational orientation of the cage with respect to the valve body is acceptable.
3. Lower the valve plug (key 4) and stem assembly into the cage. Make sure the seal ring (key 7) is evenly engaged in
the entrance chamfer at the top of the cage (key 2) to avoid damaging the ring.
4. Place the gaskets (keys 10) on top of the cage.
5. Mount the bonnet on the valve body and complete assembly using the Replacing Packing procedures in the
Maintenance section. Torque guidelines for body-to-bonnet bolting are shown in table 4.
6. If the valve has soft metal-to-metal seats, refer to the Coining Soft Metal-to-Metal Seats section, below.
Trim Assembly NPS 8 through 12
Key number locations are shown in figure 7 unless otherwise noted.
1. Install the seat ring gasket (key 11) in the lower gasket groove in the valve body (key 1), making sure the gasket is
centered in the groove and the bottom of the gasket is flush with the mating surface in the body.
2. Install threaded rods (about 6” long) into the holes on top of the cage vertically. Install hoist rings, nuts or eye bolt
on to the threaded rods.
Note
The cage and seat ring lifting holes are 1/4”-20. To prevent damage to the cage/seat ring lifting holes, fully engage the threaded
rod into the cage/seat ring hole, but do not overtighten the hoist rod. It only needs to be hand tight.
ASTM A193 B7 or comparable threaded rods are required for cage/seat ring installation.
3. Lift the cage (key 2) using the hoist rings on the threaded rods and install the cage into the valve body (see figure 3).
Any rotational orientation of the cage with respect to the valve body is acceptable. When installing the cage, take
care to lower the cage evenly and ensure the cage will not damage the flat sheet gasket (key 11).
4. Install quantity-2 cage gaskets (key 43) and make sure the gaskets sit flush on the surface of the groove.
5. Install the cage retainer (key 45) on top of the cage and a single cage gasket (key 43) on top of the cage retainer.
6. Install the bonnet gasket (key 10) into the groove around the valve body trim opening.
7. Lower the valve plug (key 4) and stem assembly through the bore of the cage retainer (key 45) and into the bore of
the cage (key 2) and gently rest the plug seating surface against the seating surface in the cage. Make sure the seal

ring (key 7) is evenly engaged in the entrance chamfer at the top of the cage retainer (key 45) to avoid damaging
the ring.
8. Mount the bonnet on the valve body and complete assembly using the Replacing Packing procedures in the
Maintenance section. Torque guidelines for body-to-bonnet bolting are shown in table 4.
9. If the valve has soft metal-to-metal seats, refer to the Coining Soft Metal-to-Metal Seats section.
Note
Be careful to prevent the bonnet from crushing the spiral wound gaskets as the bonnet is lowered on to the valve.
Damaging the gaskets will require that they are replaced.
