Fisher Actuator
Fisher 480 Series Yokeless Piston Actuators
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. They require pneumatic pressure loading from double-acting positioners or from on/off loading and unloading devices.
Features
- Yokeless construction permits a low-profile assembly by allowing close coupling to the control device; either through a bracket or by direct-mounting on a bonnet flange.
- Actuators have maximum rated travels of up to 206 mm (8.125 in).
