The ProMation Engineering PL Series Linear Electric Actuators are specially designed and engineered for precision operation of linear process control valves. They are available for NEMA 4/4X/7/9 applications. They feature field selectable stops, proportional control, and a manual override. The actuators are able to provide precise control of cooling water flow in globe valves – controlling quenching water in continuous steel production – and control of solutes in pharmaceutical processing. The actuators also feature 3 phase separators in midstream oil and gas installations. The actuators have large diameter damper systems for scrubber systems, and can handle up to 5300 lbs (23.6 kN) of force/2 inches (50mm) of travel.
