5-inch valves are relatively rare, and many units of use try to avoid this unusual size as much as possible, so if a customer anticipates ordering a large number of 5 inch gate or check valves, leave as much time as possible for ZECO to have enough time to manufacture to meet customers' requirements. However, small quantities, such as 5 inch check valves, butterfly valves each of less than 50, are normally available in safety stock to meet particularly urgent requirements.

The opening and closing parts of the flapper check valve are opened or closed by the flow of medium and force to prevent the backflow of the medium. The design is mainly composed of three main parts: the valve body, valve cover and rubber disc. Mainly suitable for horizontal installation of water supply and drainage system, can be installed at the pump outlet to prevent backflow and water hammer damage to the pump. It can also be installed on the bypass pipe of the inlet and outlet pipes of the cistern to prevent the backflow of pool water to the water supply system. Check valves are generally used for cleaning media, not for those containing solid particles and greater viscosity. As the sealing ring of this product adopts the inclined design, the closing time is short, which can reduce the water hammer pressure. The disc is made of nitrile butadiene rubber and steel plate under high temperature. It is resistant to washing and has good sealing performance. It is the valve that controls the one-way flow of medium in the pipe to prevent the reverse flow of medium in the pipe. It belongs to the automatic valve, and the opening and closing parts are opened or closed by the power of flow medium. Disc switch life up to 1 million times. It adopts full-flow area design, which has the features of small loss of water head, not the easy accumulation of sundries and easy maintenance.
