Rotary Piston Valve Actuators

Catalog pages for Piston ¼ Turn Valve Actuators

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.
