Installation
WARNING
DTo avoid personal injury, always wear protective gloves, clothing, and eyewear when performing any installation
operations.
DTo avoid personal injury or property damage resulting from the bursting of pressure retaining parts, be certain the
service conditions do not exceed the limits given in this manual.
DTo avoid personal injury or property damage that can result from the sudden release of process pressure if valve or
mating pipe flange pressure ratings are exceeded, provide a relief valve for over‐pressure protection as required by
government or accepted industry codes and good engineering practices.
DPersonal injury could result from packing leakage. See the Packing Maintenance section for adjustment information.
DCheck with your process or safety engineer for any additional measures that must be taken to protect against process
media.
DIf installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this
instruction manual.
DUse proper lifting and rigging practices while moving the valve or valve/actuator assembly.
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 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 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.
NOTICE
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 DSV1000 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:
DDo not remove the actuator from the valve while the valve is still pressurized.
DDo 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).
DAvoid injury by keeping hands, tools, and other objects away from the ball while stroking the valve.
DAlways wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal
injury.
DDisconnect 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.
DVent the power actuator loading pressure and relieve any actuator spring precompression.
DUse 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.
DDual‐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.
DA 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.
DUse lock-out/tag-out best practices and procedures to be sure that the above measures stay in effect while you work on
the equipment.
DThe 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.
DCheck 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.
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 DSV1000 packing components by key number.
Packing Disassembly
1. Isolate the 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 (or other power source) 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 disassembling the equipment.
WARNING
DSee the WARNING at the beginning of the Maintenance section for more information before removing the valve from
the pipeline.
DUse proper lifting and rigging practices while moving the valve or valve/actuator assembly.

the coupler orientation with respect to the valve drive shaft.
3. Refer to the appropriate actuator instruction manual for information on removal.
4. Remove the actuator mounting screws, bolts, or nuts while properly supporting the actuator then separate the
actuator and mounting bracket from the valve.
5. If necessary, remove the bonding strap assembly, shown in figure 2, from the valve before removing the packing
parts.
6. Remove the packing follower nuts, packing flange, and spring pack and packing follower (keys 36, 37, and 38).
7. 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.

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
adjustments, refer to the appropriate actuator instruction manual.
7. When the valve is in operation, carefully examine the packing follower region for any signs of leakage.

WARNING
DSee the WARNING at the beginning of the Maintenance section for more information before removing the valve from
the pipeline.
DUse 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 DSV1000 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 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 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 information 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. Alternately 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), 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.
NOTICE
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 DSV1000 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.
Valve Assembly
Be sure to replace valve parts in the same position and orientation from which they were removed. Use the following
steps to reassemble the valve.
Note
Clean and protect all sealing surfaces from damage while installing parts. Lubricate components when necessary as an aid for
installation and to help protect sealing surfaces.
Refer to figures 4, 5, and 6 to identify the DSV1000 valve components by key number.
During assembly, visually inspect component surfaces that interface with an O-ring or seal for any damage that may
prevent proper sealing.
1. Place both tailpieces (key 2), flange end down on a clean soft surface with the seal assembly cavity facing up. Use
caution to protect the flange end serrated surfaces.
2. Lubricate the tailpiece counterbores where the seal will insert and inject lubricant into each of the spring holes.
Install the seal springs (key 18).
3. On both seals (key 5), install the O-ring (key 15) and backup ring (key 16) in the correct orientation (see figure 5
and 6.
4. Lubricate the seal O-rings and insert the seal assembly into the tailpiece counterbores. Maintain axial alignment of
the two components as the seal assembly is pushed into place.
