Electric actuators

Process Systems Pty Ltd has a range of quarter-turn electric actuators suitable for on/off activation of ball or butterfly valves.

A powerful motor with in-built thermal protection drives a pre-lubricated heavy-duty steel gear train running in bearings. The actuator is enclosed in a powder-coated die-cast protective housing that has IP67 rating (dust tight and submersible for limited periods). All models have visual position indicator and a manual override is normally standard. The ISO 5211 mounting and female square drive allows direct coupling to valves with a similar configuration. Standard models drive through 90° and can be fitted with voltage-free contacts for end of stroke feedback.

Anti-condensation heater, torque limiting switch and voltage-free contacts for end-of-stroke positioning are also available.
