Wafer butterfly valves are newly developed on the basis of advanced foreign technology. They are of simple structure, small size, light weight and high corrosion resistance, and are easy to open and close. They are widely used in place of globe valves, gate valves and throttle valves in drainage systems, hydraulic power stations as well as production of petro-chemicals, light industrial products, textiles and foodstuffs.
