Electric flange butterfly valve can be divided into electric regulating flange butterfly valve and switching type; also according to the working condition, choose explosion-proof electric flange butterfly valve and non-explosion-proof type: it is composed of flange-connected, flange butterfly valve products made of carbon steel, ductile iron, stainless steel, etc. and electric actuator. Electric flange butterfly valve has high safety factor, better sealing performance of flange-connected pipeline, easy maintenance and easy replacement.
