Flanged butterfly valve

Butterfly valve is a simple structure, convenient operation, reliable performance of the valve, mainly by the body, butterfly plate and transmission mechanism. The butterfly plate rotates around the center axis of the valve body to realize the opening and closing or adjust the medium flow in the pipeline. Butterfly valve has the advantages of small size, light weight, rapid opening and closing, small flow resistance, widely used in petrochemical, electric power, metallurgy, water treatment and other fields.
