Pneumatic Rack and Pinion Rotary Actuators
El-O-Matic Pneumatic Rack & Pinion Rotary ActuatorDescription/Overview 
EL-O-MATIC Spring Return or Double Acting Rotary Valve Actuators are compact, simply designed control devices quality engineered to provide high torque outputs (to 40,000 in. lb..) and a high cycle, trouble-free life. 

A compact, dual opposed rack and pinion design and guide band suspension system combine to produce a symmetrically balanced, center mount actuator with a short powerful stroke, rapid response, and fully concentric operating load capability for optimum performance. 

Available manual override, the fully integrated PosiFlex™ valve positioning system, limit switches, and solenoid valves provide complete control and monitoring capability.
