Electro-Hydraulic Actuator

    • The electro-hydraulic rotary actuator offers safety and flexibility in applications, even if no air supply is provided or possible.

    • Single-acting actuators with fail safe spring unit for opening or closing a valve in the event of a power failure
    • Double-acting actuators with high performance
    • Compact unit without external piping
