electric butterfly valve picture:

working principle of the electric butterfly valve, electric butterfly valve belongs to the electric valves and electric adjusting valves, is common in industry flow control and coarse adjustment system products, electric butterfly valve consists of electric actuators work centre line stem connection disc rotates 90 degrees of motion of a valve. Generally divided into external regulation and switch type two kinds. Production of electric butterfly valve operation is simple, small flow resistance, and when the butterfly plate thickness is medium flows through the body the only resistance, at the same time, the valve has good flow control characteristics. Electric butterfly valve are well suited for large caliber situation, it is not only light weight, short, rapid opening and closing structure, convenient installation, especially soft sealing structure is more economical price, electric butterfly valve is now on the water industry can not be lack of products. Using superior material life can reach 50 million times.
