Scope of Manual
Only personnel qualified through training or experience should install, operate, and maintain Design V260 valves. If you have any questions about these instructions, contact your Fisher Controls sales office or sales representative before proceeding.
Description The Design 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.

This instruction manual provides installation, operation, maintenance, and parts information for the Design V260 control valve. Refer to separate manuals for information concerning the actuator, positioner, and accessories (see figure 1).
