Introduction
Scope of Manual
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 to
carefully 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
proceeding.
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.
