Rotary Piston Valve Actuators

FDPP PDF File ImageCatalog pages for Piston ¼ Turn Valve Actuators

Air or spring actuate piston valve actuator

Piston actuators are used for high-cycle operation due to their reliable deisgn and efficiency.  Air and springs create linear motion of an internal piston and this is converted to rotary motion due to linkage resulting in ¼ turn (90º) actuation.  The variable torque output corresponds with with the full open and closed positions characteristic of butterfly valves.
