SMS-TORK 180 Degree Pneumatic Actuator

The 180 Degree Pneumatic Actuator is an SMS-TORK rack and pinion actuator built with a full 0 to 180 degree stroke, for dampers, plug valves and other equipment that need a half-turn rotation beyond the standard 90 degree actuator.

Offered across the RA 40.8D to RA 120.8D frame sizes, the 180 degree actuator shares its extruded aluminium body, piston and bearing design with the rest of the TORK RA platform, with the valve-side ISO 5211/DIN 3337 flange and Namur VDI/VDE 3845 accessory connection kept identical to the 90 and 120 degree versions so switchboxes, positioners and solenoid valves remain interchangeable across a plant's actuator stock. Single acting (spring-return) and double acting configurations are both available.
