Key number locations are shown in figures 4, 5 and 6, unless otherwise noted. Throughout this manual, the
component key number will be identified for clarity.
1. Install a three‐valve bypass around the control valve assembly if continuous operation will be necessary during
inspection and maintenance of the valve.
2. The valve is normally shipped as part of a control valve assembly, with a factory adjusted actuator mounted on the
valve. If the valve or actuator has been purchased separately, or if the actuator has been removed, refer to the
Actuator Mounting section and the appropriate actuator instruction manual for installation and adjustment
procedures.
3. The standard valve construction allows uni-directional or bi-directional flow. If possible, install the valve in a
horizontal pipeline with the drive shaft vertical, however, the orientation of the valve does not affect the
performance.
CAUTION
Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing surfaces.
4. Provide appropriate flange gaskets, and place the valve in the pipeline. Tighten flange bolting in a star pattern to
ensure the flange gaskets are compressed evenly.
Note
Standard Fisher V270 live-loaded PTFE packing is composed of partially conductive packing rings (carbon‐filled PTFE male and
female adaptors) to electrically bond the drive shaft to the valve body. For hazardous area service, an alternate shaft‐to‐body
bonding strap is also available by using the following step (see figure 2).
5. For hazardous area applications where redundant shaft-to-body grounding is preferred, attach the optional
bonding strap assembly (key 45) to the valve drive shaft (key 4) with the clamp (key 44) and connect the other end
of the bonding strap assembly to the valve body with the mounting cap screw as shown in figure 2.

Maintenance
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.
WARNING
Avoid personal injury or equipment damage from sudden release of process pressure or uncontrolled movement of parts.
Before performing any maintenance operations:
D Do not remove the actuator from the valve while the valve is still pressurized.
D Do not loosen any pressure retaining bolting while the valve is still pressurized. This includes the body to tailpiece nuts
(key 21), packing box housing screws (key 10), packing nuts (key 36) or pipe plugs (keys 23 and 28).
D Avoid injury by keeping hands, tools, and other objects away from the ball while stroking the valve.
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. Check the
actuator cannot suddenly open or close the valve.
D Vent the power actuator loading pressure and relieve any actuator spring precompression.
D Use bypass valves or completely shut off the process to isolate the valve from process pressure, relieve any process
pressure from both sides of the valve body, and drain the process media from both sides of the valve.
D Dual‐seal constructions can retain pressure and process fluid even after process pressure has been removed from both
sides of the valve. The ball should be partially opened to relieve this pressure before disassembling or removing the
valve from the line. Take additional care if the process fluid is hot, flammable, caustic, or hazardous.
D A tip over hazard exists for the valve/actuator assembly. Ensure the valve/actuator assembly is properly secured and
always supported to prevent falling or rolling which may cause injury or property damage.
D Use lock-out/tag-out best practices and procedures to be sure that the above measures stay in effect while you work on
the equipment.
D The valve packing box housing 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 additional measures that must be taken to protect against process
media.
Packing Maintenance
Refer to figure 3 for details of the standard live-loaded PTFE packing. All maintenance operations in this section may be
performed on an unpressurized valve that is still installed inline.
Note
For additional information on the live-loaded packing system refer to the ENVIRO-SEAL Packing System Instruction Manual
(D101643X012).
Stopping Leakage
Optimum performance of the PTFE live-loaded packing system is obtained when the Belleville springs are compressed
to the required “target load.” The target load is the point where the springs are compressed to 85% of their maximum
deflection.

Instruction Manual
D104297X012
V270 Valve

Under normal conditions, the packing nuts should not require re‐tightening. However, when servicing, if the springs
do not remain at the target load of 85% compression, retighten the packing box nuts per the following:
1. Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange
(see figure 3), until the Belleville springs are compressed 100% (or completely flat).
a. For PTFE packing, loosen each packing flange nut one half turn (180_of rotation).
2. The target load of 85% compression has now been reached. If leakage continues, replace the packing components
and inspect the packing box housing bore and valve drive shaft for damage as described in the following
procedures.
Replacing Packing
Replacing the packing requires bleeding off the system and removing the actuator from the valve. Valve/actuator
adjustments cannot be made correctly without observing the fully open or closed position of the ball (key 3). It is not
necessary to remove the valve from the pipeline to make adjustments, if care is taken to note the position and
alignment of the shaft and coupler.
Refer to figure 3 which identifies the V270 packing components by key number.

parts.
7. Remove the packing follower nuts, packing flange, and spring pack and packing follower (keys 36, 37, and 38).
8. Remove the packing parts:
a. If the packing box housing (key 6) is mounted on the valve: Use a formed wire hook with a sharp end to pierce
the packing rings, and pull the rings out of the packing box housing. Do not scratch the drive shaft or packing
gland bore. Scratching these surfaces could cause leakage. Clean, inspect, and obtain replacement parts as
necessary for reassembly. Examine the drive shaft and packing gland bore for any signs of damage that may
prevent proper sealing.
b. If the packing box housing is separated from the valve (refer to Seal Ring Maintenance section of this manual for
disassembly instructions): Remove the drive shaft (key 4) from the packing box housing. With the drive shaft
removed, remove all internal packing parts. Clean, inspect, and obtain replacement parts as necessary for
reassembly. Examine the drive shaft and packing gland bore for any signs of damage that may prevent proper
sealing.
Packing Assembly
For additional information on the live-loaded packing system refer to the ENVIRO-SEAL Packing System Instruction
Manual (D101643X012).
1. If the packing housing box (key 6) is removed from the valve, use the valve assembly steps to reinstall the drive
shaft (key 4) and packing box housing assembly on the valve. (Refer to Seal Ring Maintenance section of this manual
for additional assembly instructions).
2. Place the new packing components over the drive shaft and slide each into the packing box housing until properly
seated at the bottom of the packing gland. Use the parts sequence shown in figure 3 and verify the Belleville
springs are in the correct configuration.
3. Secure the spring pack and packing follower assembly and packing flange with the packing nuts (keys 38, 37, and
36).
4. Tighten the packing flange nuts alternately and evenly, keeping the packing flange parallel with the valve flange
(see figure 3), until the Belleville springs are compressed 100% (or completely flat).
a. For PTFE packing, loosen each packing flange nut one half turn (180_of rotation).
5. If necessary, install the bonding strap assembly shown in figure 2.
6. Use the steps provided in the Actuator Mounting section to install the actuator on the valve. For actuator travel

Seal Ring Maintenance
WARNING
D See the WARNING at the beginning of the Maintenance section for more information before removing the valve from
the pipeline.
D Use proper lifting and rigging practices while moving the valve or valve/actuator assembly.
Valve Disassembly
Refer to figures 4, 5, and 6 to identify the V270 valve components by key number.
Disassemble the valve only to the extent necessary to accomplish the needed inspection and repairs. For some repairs
complete disassembly of the valve is not necessary. Follow the disassembly procedures to the point necessary to
accomplish the repair, then skip to the appropriate assembly steps to complete the reassembly of the valve. Always
clean and protect sealing surfaces from damage.
Mark parts as necessary to allow them to be returned to the same position and orientation as removed. The tailpiece,
for instance, shall be returned to the same end of the valve from which it was removed. The seal assembly shall also be
returned to the same tailpiece and in the same orientation from which it was removed.
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, shut off all pressure lines to the power
actuator, release pressure from the actuator, and disconnect the pressure lines from the actuator. Use
lockout/tagout procedures to be sure that the above measures stay in effect while working on the equipment.
2. Remove line bolting, remove the control valve from the pipeline, and clean all valve surfaces. Place the
actuator/valve assembly on a flat working surface.
3. Mark parts as necessary to allow them to be returned to the same position during re‐assembly.
4. Refer to the appropriate actuator instruction manual for info on removal. Loosen the actuator mounting screws,
bolts, or nuts while properly supporting the actuator then separate the actuator and mounting bracket from the
valve. When valve maintenance is complete, refer to the Mounting Actuator procedure in this manual to reinstall
the actuator on the valve.
5. Provide a clean soft working surface to protect the tailpiece‐flange serrated surface. Lift the valve and place it on
either tailpiece flange face. Be sure the valve is in a stable, upright position before releasing the hoist connection.
Note
If the packing is in good condition, it is possible to remove and replace the seal assembly without removing the packing box
assembly. However, the packing box assembly must be removed to remove the ball (key 3) from the valve body.
6. Remove the packing box housing socket head cap screws (key 10).
a. If necessary, two packing box housing cap screws can be used as jack bolts to assist with separating the packing
box housing assembly from the valve.
b. Remove the two plastic plugs (key 39) from the packing box housing and install two packing box housing cap
screws until contact with the body occurs. Alternatively, and evenly turn each fastener clockwise until the
packing box housing assembly is adequately separated from the valve body. Remove the packing box housing
assembly from the valve body. The packing box housing assembly includes all packing parts, drive shaft (key 4),

Instruction Manual

o‐ring seal (key 14), drive shaft bushing (key 8), and thrust washer (key 9). The two straight pins (key 7) may stay
attached to the packing box.
c. If necessary, use a punch and drive each straight pin towards the valve side of the packing box to remove.
7. If it is desired to separate the packing box assembly parts, loosen or remove the packing components and slide the
shaft down and out the valve side of the packing box. Inspect the drive shaft bushing (key 8) and the thrust washer
(key 9). If necessary, replace worn components.
8. Remove the heavy hex nuts (key 21) from the studs, if applicable, remove base brackets (key 25), and lift the upper
tailpiece from the body. If studs (key 19 and 20) are removed from the valve body, mark installed locations of long
studs (key 20) in valve body.
CAUTION
While lifting the tailpiece (key 2) from the valve body, check to see if the seal (key 5) is lifting with the tailpiece. If so, use
caution in case the seal falls out and protect the ball's spherical surface. An additional strap can be employed to ensure the
seal stays in place.
9. Turn the tailpiece assembly over so the seal is facing up, and place it on a clean soft surface to protect the flange
serrated surface. Note the tailpiece o-ring (key 13).
10. Lift the seal out of the tailpiece. Note the seal o-ring and back up ring (keys 15 and 16) and the multitude of springs
(key 18). Ensure all springs and the bearing plate dowel pins (key 22) are accounted for. Clean and protect all sealing
surfaces.
WARNING
When lifting the ball, ensure the bearing plates (key 11) are secure on the ball trunnions to prevent parts from falling which
may cause personal injury or property damage.
Note
Refer to figure 6 and note the NPS6 CL150 construction is different than the balance of the V270 product line in that it lacks
bearing plates and the ball design does not have male trunnions. Specific to the NPS6 CL150, ball removal also requires removal of
the follower trunnion (key 42) and fasteners (key 43).
11. Turn the ball (key 3) to the closed position. Use an approved lifting sling through the ball bore to lift the ball out of
the valve body. Lift the ball and set it on a clean soft surface.
12. Remove the two bearing plates (key 11) and thrust washers (key 17) from the ball. Inspect the lined bushing (key
12) in each bearing plate and the thrust washers. If necessary, replace worn components.
13. Evenly loosen the heavy hex nuts (key 21) from the studs, if applicable, remove base brackets (key 25), and lift the
body (key 1) from the lower tailpiece (key 2).
14. Lift the seal out of the lower tailpiece. Note the seal o-ring and back up ring (keys 15 and 16) and the multitude of
springs (key 18). Ensure all springs and the lower bearing plate dowel pins (key 22) are accounted for. Clean and
protect all sealing surfaces.
