The double flap check valve consists of a valve body, flaps, a valve stem, and a spring, among other components. It features a wafer connection. Due to the short closing stroke of the valve flaps and the spring loading, the water hammer phenomenon can be significantly reduced. The valve is primarily used in urban, industrial, and high-rise building water supply and drainage pipe networks. Its shorter structure length compared to general check valves makes it particularly suitable for locations with limited installation space.
