Contact SupplierRotex EHF Series Actuators are self contained; electro-hydraulic actuators are particularly well suited for applications requiring critical control and high reliability.
The EHF 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 Explosion-proof equipment is required and where pressurized air is not available or unsuitable. Within the oil and power industry, safety is of the highest importance. In emergency situations the failsafe function i.e. close or open the valve automatically with the aid of a return spring in the actuator.
