EHQ-Series conformance withIncorporating Flowbus latest technology and extensive knowledge of the valve and actuator industry, EHQ spring return actuators offer reliability and high performance in severe service applications. For example, EHQ-Series hydraulic actuators can operate in less than one second to the valve fail safe position. Depending on customer requirements and process conditions, various ancillaries such as limit switches, solenoid valve, servo valve, poppet solenoid valves etc. are optimally selected to ensure the perfect valve operation.
