VALSTEAM ADCA ELR ACTUATORS

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 (thrust rod either extended or retracted). In modulating duty, the end position seating is made via limit switches.
