This instruction manual provides installation, operation, maintenance, and parts information for the Fisher V260
control valve. Refer to separate manuals for information concerning the actuator, positioner, and accessories (see
figure 1).
Do not install, operate, or maintain a V260 valve without being fully trained and qualified in valve, actuator, and
accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important tocarefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you
have any questions about these instructions, contact your Emerson sales office

Description
V260 throttling ball valves are available in single‐seal, double block‐and‐bleed, dual‐seal, and bidirectional flow
constructions with or without attenuators. Valves with dome‐style attenuators combine the efficiency of a rotary valve
with the noise reducing capability of a special trim (figure 4). Valves without attenuators present little or no restriction
to flow at full travel.

Flow and Shutoff Direction
Unidirectional flow for Fisher V260 is forward flow.
Seal is upstream.
J Single Seal Constructions: Should be used for
unidirectional flow and unidirectional shutoff only.
J Dual Seal Constructions: V260A and V260C may be
used for unidirectional or bidirectional flow. V260B
should be used for unidirectional flow only for most
effective anti‐cavitation protection. Bidirectional
shutoff requires the dual seal construction.

APPROXIMATE WEIGHT
Key number locations are shown in figure 6, unless otherwise noted.
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 an actuator mounted on the valve. The
valve/actuator assembly is adjusted at the factory before the unit is shipped.
If the valve or actuator has been purchased separately or if the actuator has been removed, mount the actuator
according to the Actuator Mounting section and the appropriate actuator instruction manual. Make any necessary
adjustments on the bench before installing the valve in the pipeline. With the valve in the pipeline, you cannot see the
exact position of the ball to determine the fully open or closed positions.

3. Standard flow direction is shown in figure 6. If possible, install the valve in a horizontal pipeline with the drive shaft
horizontal. The actuator can be right‐ or left‐hand mounted in any of the positions shown in the actuator instruction
manual. If necessary, refer to the appropriate actuator instruction manual for installation and adjustment
procedures.
4. Be certain the valve and adjacent pipelines are free of any foreign material that could damage the valve sealing
surfaces. Impurities or entrained solids in the process fluid could plug the passages in the trim. If the process fluid is
not clean, install a filter upstream to keep the pipeline free of impurities or entrained solids.
5. Provide appropriate flange gaskets, and place the valve in the pipeline. Tighten flange bolting in a criss‐cross
sequence to ensure the flange gaskets are loaded evenly.
Note
Standard Fisher V260 valve packings (key 105) are composed of:
D
Conductive packing ring (graphite ribbon packing), orPartially conductive packing rings (For example: a carbon‐filled PTFE female adaptor with PTFE V‐ring packing or a
D
graphite‐composition packing ring with PTFE/composition packing ring)
In order to electrically bond the drive shaft to the valve body for hazardous area service, an alternate shaft‐to‐body bonding strap
can be provided by using the following step.
6. For hazardous applications, attach the optional bonding strap assembly (key 131) to the valve drive shaft (key 6)
with the clamp (key 130) and connect the other end of the bonding strap assembly to the valve body with the
mounting cap screw as shown in figure 2.
7. Connect pressure lines to the actuator as indicated in the actuator instruction manual. When an auxiliary manual
actuator is used with a power actuator, install a bypass valve on the power actuator (if one is not supplied) for use
during manual operation.
8. If the valve has ENVIRO‐SEAL™ live‐loaded packing installed, an initial re‐adjustment may not be required,
depending on your application. See the Fisher instruction manual titled ENVIRO‐SEAL Packing System for Rotary
Valves (D101643X012
) for packing instructions and adjustments (see figure 3).
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 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 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 process pressure
from both sides of the valve. Drain the process media from both sides of the valve.
D Dual‐seal valve constructions can retain pressure and process fluid even after process pressure has been removed from
both sides of the valve. 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 Carefully secure the valve in an upright position. The roundness of the flanges and valve body allow it to easily roll from
side‐to‐side. The combined weight of the valve/actuator assembly could cause injury or property damage when falling
to the side.
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 Avoid injury by keeping hands, tools, and other objects away from the ball while stroking the valve.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
D To avoid personal injury or property damage, a minimum of two swivel hoists must be used when lifting NPS 24 CL600
assemblies.
Packing Maintenance
Note
For the ENVIRO‐SEAL Packing System, refer to the separate ENVIRO‐SEAL Packing System for Rotary Valves instruction manual,
D101643X012
Stopping Leakage
For standard PTFE V‐ring packing, leakage around the packing follower may be stopped by tightening the packing
follower nuts.
If the packing is relatively new and tight on the drive shaft, and if tightening the packing follower nuts does not stop
the leakage, the drive shaft may be worn or nicked so that a seal cannot be made. If the leakage comes from the
outside diameter of the packing, the leakage may be caused by nicks or scratches on the packing box wall. Inspect the
drive shaft and packing box wall for nicks or scratches while performing the following procedure.
