PA series pneumatic multi-spring actuators with rolling diaphragm, offering decreased hysterisis and good linearity throughout the operating range. Available with direct or reverse action for modulating and on/off services.
Electric linear actuators EL series for modulating and open-close duty of control and process technology to operate control valves. The self-locking stem/stem nut is driven by an electric motor via a gearing. Load and limit switches define the stops for the end positions.
Electric linear actuators ELR series for modulating and open-close duty of control and process technology to operate control valves. The self-locking stem/stem nut is driven by an electric motor via a gearing. Load and limit switches define the stops for the end positions. In case of power failure, the electric linear actuator runs spring-driven into the respective fail-safe position.
