RCESRROT
RCE electro-hydraulic actuators is a range of rigid actuators for on/off and positioning with high torques in relation to size. Torques ranging from 50-5,000 Nm. The function is a cost effective alternative to a spring return electric actuator.
The unit consists of a hydraulic spring return actuator with manual override, electric motor, hydraulic pump and tank.
The series has a wide range of applications and is resistant to environmental influence, even in marine environments. The electro-hydraulic actuators are recommended within district heating plants, oil and gas depots where explosionproof equipment is required and where pressurised air is not available or unsuitable.
General features:
Within the oil and power industry, safety is of the highest importance. In emergency situations the failsafe function closes or opens the valve automatically with the aid of a return spring in the actuator.
RCE is available in designs where the spring opens or spring closes. The actuator is constructed for direct mounting on valves according to ISO-standards.
