WARNING
Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the valve
assembly where service conditions could exceed the limits given on the appropriate nameplates, or the mating pipe flange
rating. Use pressure‐relieving devices as required by government or accepted industry codes and good engineering
practices.
Check with your process or safety engineer for any other hazards that may be present from exposure to 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

unless otherwise indicated.
CAUTION
To prevent product damage during storage, keep the valve body cavity dry and clear of foreign material.
1. If the valve is to be stored before installation, protect the flange mating surfaces and keep the valve body cavity dry
and clear of foreign material.
2. Install a three‐valve bypass around the control valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
3. A V500 valve is normally shipped as part of a control valve assembly, with a power or manual actuator mounted on
the valve. If the valve and actuator have been purchased separately or if the actuator has been removed from the
valve, mount the actuator according to the Actuator Mounting procedure. Also, adjust the actuator travel using the
Adjusting Actuator Travel procedure before installing the valve. The necessary measurements cannot be made with
the valve installed.
4. Before starting the actual installation of the valve, determine the proper installation orientation of the valve plug
(key 2) and actuator. Determine the flow direction of the process fluid through the valve. See figure 2.

5. Before installing the valve, make sure the flow direction arrow (key 32) on the valve matches the actual process fluid
flow direction through the valve for the application where the valve will be installed.
6. Install the flange gaskets and insert the valve between the mating pipeline flanges. For flangeless valve bodies, also
make sure the mating line flanges are aligned. Use flat sheet gaskets compatible with the process media, or spiral
wound gaskets with compression‐controlling center rings.
Ceramic Trim
Some types of ceramic trim, including the VTC (very tough ceramic) variety, can create a spark under certain
circumstances. When the edge of a ceramic part is struck against a second ceramic part with enough force, a spark can
be created.
WARNING
Avoid personal injury and property damage from ignition of process fluid caused by sparks from ceramic trim.
Do not use ceramic trim where the process fluid is unstable or if it is an explosive mixture (such as air and ether).
WARNING
The valve drive shaft is not necessarily grounded to the pipeline when installed. Personal injury or property damage could
result if the process fluid or the atmosphere around the valve is flammable, from an explosion caused by a discharge of
static electricity from the valve components. If the valve is installed in a hazardous area, electrically bond the drive shaft to
the valve.

Instruction Manual
D100423X012
V500 Valve

1. Prepare to install the line bolts and nuts. For flangeless valves, consult figure 3 before installing the line bolts and
nuts. Figure 3 shows the line bolt clearances required when installing flangeless valves.
Note
Standard PTFE packing is composed of a partially conductive carbon‐filled PTFE female adaptor with PTFE V‐ring packing. Standard
graphite packing is composed of all conductive graphite ribbon packing rings. Alternate shaft‐to‐valve body bonding is available
for hazardous service areas where the standard packing is not sufficient to bond the shaft to the valve (see the following step).
2. For hazardous applications, attach the bonding strap assembly (key 131) to the shaft with the clamp (key 130) and
connect the other end of bonding strap assembly to the valve body with the cap screw (key 25). See figure 4.
For all valve bodies, install the line bolts and nuts; then, tighten them using accepted bolting procedures. These
procedures include, but are not limited to, lubricating the line bolts and hex nuts and tightening the nuts in a crisscross
sequence to ensure proper gasket load.
3. If a purge is desired for the purged bearing construction, remove the pipe plugs (keys 29 and 24) and install the
purge lines. Purge pressure should be greater than the pressure within the valve and the purge fluid should be as
clean as possible.
4. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When a manual actuator is
used with a power actuator, install a bypass valve on the power actuator (if not already supplied) for use during
manual operation.
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. Check with your process or safety engineer for any
other hazards that may be present from exposure to process media.
If the valve has ENVIRO‐SEALt live‐loaded packing installed readjustment will probably not be required. See the
Emerson Automation Solutions instruction manual entitled ENVIRO‐SEAL Packing System for Rotary Valves
(D101643X012
) 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 Kit section later in this manual.
Maintenance
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.
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.
7
V500 Valve
November 2018
D Vent the power 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 area 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.
D Check with your process or safety engineer for any other hazards that may be present from exposure to process media.
Instruction Manual
D100423X012
Valve parts are subject to normal wear and must be inspected and replaced as necessary. The frequency of inspection
and replacement depends upon the severity of service conditions.
As used in these instructions, the term “actuator” refers to power actuators (such as pneumatic diaphragm or piston
actuators) or manual actuators (such as handwheel or handlever actuators).
Packing Maintenance
Key numbers are referenced in figures 11 and 13 unless otherwise indicated.
Note
For the ENVIRO‐SEAL packing system, refer to the Parts Ordering section for retrofit kits and parts kits(see figure 14). Refer to the
separate ENVIRO‐SEAL instruction manual for maintenance instructions.
Standard ENVIRO‐SEAL packing systems can be used in vacuum service with packing rings in the standard orientation. It is not
necessary to reverse the ENVIRO‐SEAL PTFE packing rings.
Stopping Leakage
All maintenance procedures in this section may be performed with the valve body (key 1) in the line.
For packing other than spring‐loaded packings, leakage around the packing follower (key 14) can be stopped by
tightening the packing flange nuts (key 16). If leakage cannot be stopped in this manner, replace the packing
according to the Replacing Packing procedure.
If the packing is relatively new and tight on the valve shaft (key 3), and if tightening the packing nuts does not stop
leakage, it is possible that the valve shaft is worn or nicked so that a seal cannot be made. If the leakage comes from
the outside diameter of the packing, it is possible that the leakage is caused by nicks or scratches on the packing box
wall. Inspect the shaft and packing box wall for nicks or scratches when performing the following procedures.
Replacing Packing
Note
If the valve has ENVIRO‐SEAL live‐loaded packing installed, see the separate ENVIRO‐SEAL instruction manual.
This procedure may be performed without removing the actuator from the valve body if adding PTFE/composition
packing rings as a temporary measure. However, the actuator must be removed if replacing any other kind of packing
or if the metal packing parts (keys 14, 17, and, if used, 18) need to be replaced.
8
Instruction Manual
D100423X012
V500 Valve
November 2018
Removing the Packing
1. Isolate the control valve from the line pressure, release pressure 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,
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.
CAUTION
When the actuator is removed from the valve, do not use a hammer or similar tool to drive the lever or actuator off the
valve shaft. Driving the lever or actuator off the valve shaft could damage the valve plug, seal, and valve.
If necessary, use a wheel puller to remove the lever or actuator from the valve shaft. It is okay to tap the wheel puller screw
lightly to loosen the lever or actuator, but hitting the screw with excessive force could damage the valve plug, seal, and
valve.
2. If necessary, remove the cap screws (key 25) and hex nuts (key 26). Then remove the actuator while referring to the
actuator manual for assistance.
3. Remove the packing nuts (key 16) and packing follower (key 14).
4. Remove the old packing rings (key 13), packing box ring (key 17), and, if used, the lantern ring (key 18).
CAUTION
Do not scratch the valve shaft or packing box wall. Scratching these surfaces could cause leakage.
5. Clean all accessible metal parts and surfaces to remove particles that would prevent the packing from sealing.
6. If necessary, complete the steps in the Replacing the Valve Plug, Shaft, and Bearings section, and return to the
Installing Packing steps below.
Installing Packing
1. Install the new packing rings and packing box ring by stacking the parts as shown in figure 5. Make sure split rings
are arranged so that the splits do not line up to form a leak path. Then slide the stack into the packing box as far as
will go while being careful to avoid trapping air among the rings.
2. Install the studs, packing follower, and nuts.
CAUTION
To prevent possible product damage or leakage, make sure the valve plug remains in the closed position when installing
new packing parts.
3. Make sure the valve plug is in the closed position when installing new packing parts.
4. Insert a screw driver, pry bar, or similar tool between the lower ear of the plug and the valve body (see figure 6). Use
the pry to move the plug tightly against the thrust washer and bearing on the actuator side of the valve. Keep the
valve plug in that position until you have completed the packing installation.
5. Tighten packing flange nuts enough to stop leakage under normal conditions.
6. Mount the actuator while referring to the actuator mounting procedures of the actuator instruction manual. You
must complete the Adjusting Actuator Travel procedure in this manual before installing the valve in the pipeline,
due to the measurements that must be made during the actuator adjustment process.
9
V500 Valve

7. When the control valve is being put back into operation, check the packing follower for leakage, and retighten the
packing nuts as necessary.
Instruction Manual
D100423X012
Replacing Retainer, Seat Ring, and Face Seals
This procedure is to be performed if the control valve is not shutting off properly, if the port diameter is to be changed
by installing a different seat ring, or if seat ring inspection is necessary. The actuator and valve (key 1) must be
removed from the pipeline; however, the actuator may remain mounted during this procedure.
A retainer tool is required to remove the retainer (key 5), seat ring (key 4), and face seals (key 8). If specifically ordered,
a tool is supplied with the valve; a tool can also be ordered individually. If desired, a tool can be machined using the
dimensions shown in figure 7.
During assembly, handle the retainer, seat ring, and face seals carefully. Critical areas that must be protected are the
threads and inner surface of the retainer (key 5), the sealing surfaces of the face seals (key 8), the face seal grooves in
the seat ring (key 4), the shutoff surface of the seat ring, and the face seal surface in the valve body (key 1).
A new retainer gasket (key 11) is required whenever the retainer (key 5) is removed. Other parts in good condition can
be reused.
Disassembly of Retainer, Seat Ring, and Face Seals
Key numbers are shown in figures 11 and 13 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.
2. Remove line bolting. Then, remove the control valve from the pipeline and place the valve on a flat surface with the
retainer (key 5) facing up.
3. Rotate the valve shaft (key 3) to move the valve plug (key 2) into the open position.
Note
The retainer (key 5) was installed at the factory using the torque listed in figure 8.
4. Remove the retainer by engaging the retainer tool, attaching an impact wrench or other suitable tool, and
unscrewing the retainer. Inspect the retainer.
CAUTION
Place the retainer on a protected, flat surface where the threads and inner surface will not be contaminated or damaged.
5. Remove the retainer gasket (key 11). Inspect the gasket surfaces on the valve body (key 1).
6. Lift out the seat ring (key 4) and both face seals (key 8). Inspect the parts and place them on a flat, protected
surface.
7. Inspect the shutoff surface of the valve plug. If it is worn, nicked, or scratched, proceed to the Replacing Valve Plug,
Shaft, and Bearings procedure. If the parts are in good shape and do not require maintenance, continue to the
Assembly procedure.

Assembly of Retainer, Seat Ring, and Face Seals
WARNING
Seat ring installation requires that the valve plug (key 2) remain in the open position.
To avoid personal injury or damage to tools, valve parts, or other items resulting from plug closing, prevent plug travel by
using travel stops, manual actuators, constant supply pressure to a pneumatic actuator, or other steps as appropriate.
When installing the seat ring, keep hands, tools, and other objects out of the valve.
1. Apply enough supply pressure to the actuator to open the valve plug, or take other steps to hold the valve plug
open.
2. Clean the valve body, the retainer threads, the retainer gasket surface, and the seat ring sealing surface.
3. Using either face seals (key 8) in good condition or new face seals, place one seal in the seat ring cavity.

SEAT RING AND RETAINER CLEARANCE
Note
The seat ring (key 4) may have one or two shutoff surfaces. The shutoff surfaces are the narrow, rounded edges of the seat ring
bore. Inspect the seat ring and locate the shutoff surfaces before proceeding.
4. Insert the seat ring into the seat ring cavity with the correct shutoff surface facing the valve plug and shaft. The seat
ring will cover the face seal installed in step 3.
5. Place the second face seal on the seat ring.
6. Apply anti‐seize lubricant to the gasket surface in the valve body. Install the gasket (key 11), while making certain
that for NPS 2 through 8 sizes the concave surface of the gasket is up (hump surface of gasket down).
7. Apply anti‐seize lubricant to the threads and bottom of the retainer (key 5). Thread the retainer into the valve body.
8. Refer to figure 7. With the appropriate torque indicating tool, tighten the retainer to the torque listed in table 7.
9. A gap between the seat ring (key 4) and retainer (key 5) allows the seat ring to self‐center. Applying the proper
amount of torque during installation should position the retainer and seat ring properly. However, for NPS 2
through 8 valves, use a feeler gauge to measure between the parts as shown in figure 13, making certain the
necessary clearance exists. Compare the measured gap to the clearance in table 8 and proceed as follows:
D If the measured clearance is within table values, proceed to the next step.
D If the measured gap is larger than the maximum, tighten the retainer—apply more torque than that listed in table 7,
if necessary—until the clearance is within maximum and minimum values.
D If the measured clearance is smaller than the minimum, remove the retainer, seat ring, and face seals, clean the
parts, and reassemble so as to obtain the necessary clearance.
10. Perform the Adjusting Actuator Travel procedure and then install the control valve in the pipeline.

Replacing Valve Plug, Shaft, and Bearings
Perform this procedure to replace the valve plug (key 2), expansion pin assembly (keys 9 and 10), shaft (key 3), or
bearings (key 6). These parts are independently replaceable; for example, installing a new valve plug does not require
replacing a reusable valve shaft or expansion pin assembly. Key numbers refer to figures 11 and 13 unless otherwise
indicated.
Disassembly of Valve Plug, Shaft, and Bearings
WARNING
To avoid personal injury resulting from contact with edges of the valve plug (key 2) and seat ring (key 4) during plug
rotation, stay clear of the plug edges when rotating the plug. To avoid damage to tools, valve parts, or other items
resulting from valve plug rotation, keep tools and other property away from the edges of the plug.
CAUTION
To avoid increased leakage, increased valve component wear or possible damage to the valve body (key 1), plug (key 2),
shaft (key 3), and bearings (key 6) resulting from a sharp blow to the actuator body or valve parts, use a wheel puller to
separate the actuator parts from the valve shaft.
Do not drive the actuator parts off the valve shaft since this could move the valve bearings, shaft, and plug away from
proper alignment, causing improper seating of the plug. Such misalignment may result in damage to valve components if
the valve is returned to service without disassembly and inspection of the valve plug alignment.
Note
Following removal of the valve from the pipeline and partial disassembly, the valve shaft may be used to remove bearings in
accordance with the procedure described in step 8, below.
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 actuator cover. Note the actuator orientation with respect to the valve body and the lever orientation
with respect to the valve drive shaft (see figure 2). Remove the lever but do not loosen the actuator turnbuckle
adjustment. Remove the actuator mounting screws and nuts, and remove the actuator. If necessary, refer to the
actuator instruction manual for assistance.
3. With the valve body (key 1) out of the pipeline, loosen the packing nuts (key 16). If the packing is to be reused, do
not remove it. However, Emerson Automation Solutions recommends that the packing be replaced whenever the
drive shaft is removed.
4. Rotate the plug (key 2) to the fully open position.

5. Refer to figure 8. Find the expansion pin (key 9) and the taper pin (key 10) inside of it. These parts are holding the
valve plug in position on the shaft. Find the larger hole in the valve plug hub where these pins enter the hub. On the
opposite side of the plug hub is a smaller hole where the chamfered end of the expansion pin rests on the inner lip
of the hole. Using a pin punch and hammer, strike the chamfered end of the expansion pin through the smaller
hole. Remove both pins from the valve plug hub in the direction shown in figure 8.
Driving the pins in the other direction will tighten the pins.
WARNING
To avoid personal injury or damage to tools, valve parts, or other items and plug damage resulting from the valve plug
falling from the valve body, support the plug to prevent it from falling as the shaft (key 3) is being removed.
6. Pull the shaft (key 3) from the valve body. If the shaft cannot be removed by hand, attach a slide hammer or similar
tool to the spline end of the valve shaft. Each shaft, on the NPS 6 and 8 sizes, has a tapped hole at the spline end of
the shaft; refer to table 9 for thread sizes.

7. Remove the plug and thrust washer (key 12) from the valve body.
Note
Two shaft bearings (key 6) are located inside the valve body on either side of the valve plug. Only one of these two bearings is
identified by key 6. The other bearing is located along the valve shaft on the other side of the valve plug.
8. If the shaft bearings are to be replaced, remove the packing (key 13).
9. If the bearing closest to the packing requires replacement and cannot be removed by hand, press it out using a ram
with dimensions given in figure 9 and table 10.
CAUTION
Ensure the bearing stop is not moved when pressing out the bearing. Movement may cause the new bearing and valve plug
to not be centered with the seal, causing possible leakage or damage of the seal/plug.
Insert the ram through the packing box and press the bearing into the valve body cavity. The bearing stop (key 7) does
not need to be removed; take care not to move the bearing stop when pressing out the bearing.
10. If the second bearing (key 6) requires replacement and cannot be removed by hand, use one of the following
methods:
D Knock or pry the bearing out, or
D Use the valve shaft as a piston to drive the bearing from the valve body. To accomplish this, first, fill the bearing bore
with a heavy grease and then insert the end of the shaft back through the valve body and into the grease‐filled
bearing. Protect the splined end of the shaft with, for example, a block of wood; then strike the protected end.
When the shaft is struck, it will act as a piston, pushing the grease into the bearing bore. The grease will then force
the bearing out of the bore and farther along the shaft. Soon, the bearing will be positioned for easy removal.
11. If used, remove the O‐rings (keys 19 and 20) from the bearings. Also, remove the pipe plug (key 29).

Assembly of Valve Plug, Shaft, and Bearings
Note
Before starting to assemble the valve components, place the valve body (key 1) on a flat surface with the retainer (key 5) facing
down as shown in figure 10. This orientation of the valve body allows easier installation of the valve plug.
1. Thoroughly clean the parts before assembly.
2. If O‐rings (keys 19 and 20) are used, apply a small amount of lubricant to the O‐rings so the bearings will easily slide
into the valve body. Insert the smaller O‐ring (key 20) inside the bearing and the larger O‐ring (key 19) around the
outside of the bearing.
CAUTION
To avoid damage to O‐rings resulting from contact with sharp edges within the bearing holes, use appropriate care when
installing the O‐rings.
3. Slide the bearings (key 6) and O‐rings (keys 19 and 20), if used, into the valve body as shown in figures 13 and 12.
Note
Place the valve body on a flat surface with the retainer (key 5) facing down so that you can look into the valve body cavity. This
orientation makes installing the valve plug easier.
4. Inspect the valve shaft (key 3). Insert the shaft end opposite the splined end into the packing box and through the
set of bearings installed in the packing box in step 3. Stop before the shaft enters the main valve body cavity.
Support the splined end of the shaft.
5. Determine the correct orientation of the valve plug (key 2) required by the specific installation orientation of the
valve and the flow direction of the process fluid. See figure 2.
6. Inspect the valve plug. Note the location of the larger hole on the valve plug hub. Place the valve plug in the valve
body cavity.
7. Position the valve plug so that the larger hole is facing up, away from the seat ring and retainer. The valve plug must
also be oriented so that the seating surface of the plug is correctly positioned for the specific application as shown
by the illustrations in figure 2.

Note
Before proceeding, inspect the valve plug position once again to ensure the correct orientation as described in step 6. If the valve
plug is not properly installed, it will not rotate properly and will not shutoff in service.
8. Hold the thrust washer(s) (key 12) between the valve plug (key 2) and the bearing installed next to the packing as
shown in figures 11 and 13. Then slide the valve shaft (key 3) from the packing box into the valve body through the
thrust washer(s) and plug. If the shaft material is S17400, use two 0.7938 mm (1/32 inch) 17‐7 PH thrust washers. If
the shaft material is S20910, use one 1.587 mm (1/16 inch) alloy 6 thrust washer.
9. Secure the valve plug in the correct open position. Inspect the splined end of the valve shaft and locate the slash
mark on the splined end. Rotate the valve shaft until the slash mark is vertical and facing out from the center of the
shaft in the same direction as the valve plug seating surface. See figure 10.
Note
When the valve shaft is correctly positioned, the slash mark on the splined end will be parallel with the plug shutoff surface. See
figure 10.
10. Look into the valve body and find the larger pin hole on one side of the valve plug hub. Find the smaller hole on the
opposite side of the hub. These holes should line up with the hole through the shaft (key 3).
Note
If the holes in the valve plug hub do not line up with the hole in the shaft, check the slash mark on the splined end of the shaft.
Make sure the shaft and plug are properly oriented.
CAUTION
For NPS 1 through 2, use only N10276 expansion and taper pins (keys 9 and 10) with VTC (ceramic) valve plug. With any
other pin material, there is danger of the pins expanding and cracking the plug as temperature rises. For that reason, the
19
V500 Valve
November 2018
NPS 1 through 2 VTC valve plugs are sold only as a set that includes N10276 pins. Use only the pins that are furnished with
the set.
Instruction Manual
D100423X012
Components of the VTC valve plug assembly for the NPS 3 through 8 cannot be repaired in the field.
11. Place the chamfered end of the expansion pin (key 9) into the larger hole in the plug hub (see figure 11).
CAUTION
To avoid damage to the expansion pin, valve plug, or shaft resulting from the application of excessive force on the
expansion pin, use appropriate care when driving the expansion pin through the plug hub and shaft. Use the right tool. Do
not use excessive force.
12. Drive the expansion pin into the larger hole until the chamfered end of the pin reaches the inner lip of the smaller
hole on the opposite side of the plug. Closely observe the progress of the pin to avoid striking it after it has reached
the lip of the smaller hole.
13. Place the taper pin (key 10) into the open end of the expansion pin. Drive the taper pin into the expansion pin until
the pins, plug, and shaft are snug. Do not attempt to drive either pin flush with the hub.
14. Rotate the plug by hand to check that it rotates properly. If rotation interferes with the valve body, drive out the
pins (keys 9 and 10), remove the valve shaft (key 3), and repeat this procedure starting with step 4.
15. If used, install the pipe plug (key 29).
16. If the seat ring (key 4), face seals (key 8), and retainer (key 5) need to be installed, complete the assembly
instructions in the procedure for Replacing Retainer, Seat Ring, and Face Seals. If the seat ring has previously been
installed, proceed to Adjusting Actuator Travel.
Adjusting Actuator Travel
Perform this procedure whenever the actuator is removed or disconnected from the valve and whenever the seat ring
and retainer (keys 4 and 5) are removed. Actuator travel that is too short will increase shutoff leakage; too much travel
will cause excessive plug and seat ring torque.
Any of the Fisher pneumatic (spring‐and‐ diaphragm, piston, or spring‐return piston), electric, electrohydraulic, or
manual actuators‐‐or any other operator‐‐must be adjusted for use with a V500 valve so that the valve plug is rotated
to the fully closed position. The fully closed position is obtained when a gap of 0.001 inch exists between the seat ring
(key 5) and retainer (key 4).
Note that this gap is also measured when assembling the seat ring, retainer, and face seals to ensure correct assembly.
Measure the gap according to this procedure to ensure proper actuator adjustment. Merely completing the assembly
measurement is not sufficient.
Travel for different actuators is adjusted differently (some use turnbuckle assemblies; some use externally adjusted
travel stops; others use internal limit switches). Refer to the actuator instruction manual for adjustment instructions.
1. Mount the actuator following the instructions in the actuator instruction manual. Refer to figure 3 to select
actuator mounting style and position and to orient the actuator lever with the valve shaft (key 3).
2. For actuators with clamped levers,
CAUTION
When installing the actuator onto the valve, do not use a hammer or similar tool to drive the lever or actuator onto the
valve shaft. Driving the lever or actuator onto the valve shaft could damage the valve plug, seal ring, and other valve
components.
20
Instruction Manual
D100423X012
D Clean the valve shaft splines and actuator lever splines to be sure the actuator lever will slide on easily.
D Pull the valve shaft (key 3), by hand, toward the packing (key 13). Or,
D If the lever does not slide easily on the valve shaft, carefully wedge the valve plug solidly against the actuator‐side
thrust washer using a screwdriver or similar tool in the same direction as the pry bar shown in figure 6.
3. Clamp the lever to the valve shaft.
V500 Valve
November 2018
CAUTION
Do not apply full actuator signal (pressure or power) to the actuator in the next step. Full signal may wedge the valve plug
into the seat ring. Use a regulated signal source and gradually increase the signal to slowly stroke the actuator.
4. Adjust actuator travel and stroke the actuator so that the plug is close to but not contacting the seat ring at full
actuator travel. If available on electric actuators, use a manual handwheel to position the plug.
5. Adjust travel, using full actuator signal, until the valve plug contacts the seat ring around its full circumference. This
contact self‐centers the seat ring on the valve plug.
6. Continue to adjust travel until a gap of 0.001 inch exists between the seat ring and retainer, as shown in figure 13,
at full actuator travel.
7. Refer to the actuator instruction manual to lock the actuator travel adjustment.
Changing Valve Flow Direction
The V500 valve may be installed in either forward or reverse flow service. Forward flow enters the seat ring first, then
flows past the valve plug. If changing flow direction is necessary, release all pressure from the valve and actuator.
Remove the control valve assembly from the pipeline and rotate the assembly about the valve shaft to put the retainer
end of the valve where the other end was. Refer to the procedure for Changing Actuator Mounting Style if the actuator
must be repositioned, and refer to the Installation section to install the control valve assembly. Be sure to reposition
the flow direction arrow on the valve body.
Changing Actuator Mounting Style
Refer to figure 3 of this manual and the actuator instruction manual when changing mounting styles or positions.
Right‐hand mounting places the actuator on the right side of the valve as viewed from the upstream side of the valve;
left‐hand mounting places the actuator on the left side of the valve. Remember that the upstream side of the valve
inlet is the retainer end of the valve body for forward flow and the other end of the valve body is the upstream side for
reverse flow.
Complete the Adjusting Actuator Travel procedure whenever the actuator is removed.
Parts Ordering
A serial number is assigned to each valve and stamped on the nameplate. Always refer to the valve serial number when
corresponding with your Emerson sales office
desired material.
WARNING
. When ordering replacement parts, also specify the part name and
Use only genuine Fisher replacement parts. Components that are not supplied by Emerson Automation Solutions should
not, under any circumstances, be used in any Fisher valve, because they may void your warranty, might adversely affect the
performance of the valve, and could cause personal injury and property damage.
