Spring-return proportional-type linear actuators with adjustable zero-point calibration, featuring high force output, compact design, lightweight construction, and rapid response.
Request a QuoteThe pneumatic piston actuators produced by our company are spring-return proportional-type linear actuators with adjustable zero-point calibration. Featuring high force output, compact design, lightweight construction, rapid response (1.2-4.5 seconds), and excellent vibration resistance, they are compatible with single-seat globe valves, angle valves, cage valves, and other linear motion control valves.
When equipped with a positioner, they function as pneumatic piston control valves. Selectable spring ranges allow customization for required allowable pressure differentials. Available in SA Series (spring-return for shut-off valves) and SN Series (double-acting springless for high-pressure applications).
