      The electric butterfly valve is powered by 220V AC power supply and receives 0~10mA or 4~20mA standard signal. It drives the valve opening to correspond with the operation signal, so as to adjust the medium pressure, flow rate and temperature. The structure is simple and the operation is convenient. The valve plate is elliptical inclined structure, and the leakage is small. It is suitable for large caliber and large flow occasions. Because of its self cleaning function, it is especially suitable for ventilation systems and the regulation of suspended medium.


      The butterfly valve is matched with the electric actuator. It can change the flow rate of various liquid, gas, dust and flue gas through different control signals in metallurgical, electric, petrochemical, light imitation, building materials and environmental protection industrial pipelines, thus realizing the automatic adjustment and remote control of industrial process.
