ELR

The ADCATrol ELR series linear electric actuators are designed for operation of control valves in modulating and on/off services in process engineering and industrial applications. The self-locking stem nut is driven by an electric motor via a gearing. Load-dependent switches and/or mechanical limit switches define the stops for the end positions. In case of power failure, the electric linear actuator runs into the respective fail-safe position by spring force (thrust rod either extended or retracted). In modulating duty, the end position seating is made via mechanical limit switches.
