1. Product IntroductionElectric ventilating butterfly valve is built-up by Rotork electronic type quarter-turn actuator and ventilating butterfly valve. It use the same material with valve body and to processed into seal ring. Its applicable temperature and corrosion resistance performance depend on the material of valve body. The nominal pressure<0.6Mpa, and its leakage rate controlled within 2 Percent of the maximum flow volume. It used as ventilating and regulating the medium flow of pipeline in the industry, metallurgy, environment protection and other field. 2. Performance FeatureThe valve with small driving torque, on-off flexible and easy to operating.Can effectively avoid the stuck phenomenon which caused by thermal expansion. Short structure size, light weight and easy installation.Weld by steel plate. Setting an oil sealing ring on the valve body, without any visible gap between it, and small leakage rate.Operating principle of electric ventilating type butterfly valveElectric ventilating butterfly valve is built-up by electronic type quarter-turn actuator and ventilating butterfly valve. Because of the mechatronics structure design, it has the functions of inside servo operating, aperture signal position feedback, position indication and manual manipulation. It has virtue of strong function, reliable performance and accurate control. It use AC220V or AC380V voltage as power to accept the (4-20mA or 1-5VDC)current signal or voltage signal which input by controlling system and then can operating under the controlling. And to accomplish the proportional control or on-off control of process fluid medium.
