Pneumatic Rotary Actuators

JM Rack & Pinion Series

Pneumatic Rotary Actuator

Actuators are the major component of an automatic control system. As air flows in, it moves the piston which causes a torque to be developed in the connecting rod. This turning movement is used to operate automatic valves, dampers, bells or other shutters. 

JossMin offers a  robust and compact quarter-turn pneumatic rotary actuator model housed in an SS investment cast and anodized aluminium body featuring a pneumatically operated dual rack and pinion design. The body offers interfaces for valve mounting arrangements and auxiliary accessories. The build is optimized to work at low pressure and guarantees a quick response while ensuring no metal-to-metal contact. Our Single Acting pneumatic actuators use springs to ensure quicker response time.
