GB two-piece flanged ball valve

Ball valve is a simple structure, convenient operation, reliable performance of the valve, mainly by the body, ball and transmission mechanism. The ball rotates around the central axis of the valve body to realize the opening and closing or adjust the medium flow in the pipeline. Ball 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.
