Elomatic 1/4 Turn Rack & Pinion Actuators


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.

Revo 1/4 Turn Rack & Pinion Actuators

The REVO® Series R range of actuators is ideal for operating quarter-turn valves, especially butterfly, ball and plug valves. Typical applications are 90º or 180º rotary motion and Multiposition function.

The linear counter movement of the pistons is transmitted into the required 90º travel by means of the integrated racks of the pistons and the pinion.

All REVO actuators are suitable for on/off or modulating control operations. Double-acting actuators are operated by air in both directions (open and closed) whilst single-acting actuators can be supplied with springs to open or close. On air failure these will then go into a fail-safe position.
