ANSI GB Standard Cast Steel Stainless Steel Dual Plate Wafer Type Check Valve
Product introduction:
Check valve also known as automatic safety mechanism called a is used to allow fluids and gases to flow in one direction while preventing reverse flow. These valves seal tightly to stop leaks and guarantee that gases or liquids are flowing in the proper direction and prevents major harm to pumps and compressors by regulating the flow of liquids. It is also known as a one-way valve. Fluids enter the valve at the inlet under pressure, where they push the disc away from the valve’s seat and out the outlet. The disc automatically returns to its seat to stop the flow if there is a pressure drop. It is robust, long-lasting, and constructed of high-quality materials. To stop backflow, it is typically put in pipelines. The flow can freely move one direction through a check valve, but if the flow changes, the valve will close to safeguard the piping, other valves, pumps, etc. Water hammer may happen if the flow reverses and there is no check valve in place. A pipeline or other components can easily be damaged by water hammer, which frequently occurs with great power.
Dual-plate wafer type check valve consists of valve body, valve disc, valve rod, and spring parts etc. The check valve adopts wafer type, butterfly plate is two semicircular, and adopts spring forced reset, sealing surface can be body hard-facing wear-resistant material or rubber lining, wide range of use, reliable sealing.
The disc shutoff stroke is very short and under the effect of the spring, the valve can close quickly and prevent the big noise from water-hammering. It is widely used in water supply and drainage system, high-rise building and industrial park, because of its surface distance is short than other check valve, so it is more convenient for the confined space installation.
