The Fisher 1061 pneumatic piston rotary actuator is used to operate splined-shaft rotary control valves such as the Vee-Ball valves, eccentric disc valves, and butterfly valves.

Fisher® 1066 and 1066SR actuators are compact, piston, rotary actuators for throttling (with 3710 pneumatic or 3720 electro-pneumatic positioners) or on-off applications.

Fisher 480 Series actuators are yokeless piston actuators that are used in either throttling or on-off applications with ball valves, butterfly valves, louvers, dampers, and rheostats.

The Fisher 585C linear piston actuator is a powerful, double-acting actuator that provides accurate throttling or on-off operation for sliding-stem control valves.
