Double-Flange Rubber-Lined Butterfly Valve serves as an "on-off" or "regulating" valve for fluid control in industrial piping systems. Its key feature is the integral vulcanized rubber lining on the inner wall of the valve body, which significantly enhances durability and sealing performance.The securely bonded rubber lining prevents shifting or bulging, ensuring high reliability and durability. The term "flange" refers to the connection method at both ends of the valve; equipped with flanges, it connects to corresponding flanges on the pipeline via bolts—a highly secure arrangement that is particularly well-suited for high-pressure, large-diameter piping.It is suitable for applications involving water, wastewater, gases, and mild chemical systems.
