EHA / EHAS High Pressure ELECTRO-HYDRAULIC Actuators

Double-acting and spring return electro-hydraulic solutions for on-off valves on heavy duty service, suitable for high pressure supply. Models available for output torques to 60,000 Nm.

EHA / EHAS electro-hydraulic actuators use a self-contained power unit to provide operation and control of ¼” turn valves in on-off applications when the primary power source (instrument air or hydraulic supply) is unavailable.
