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
