ANSI GB Standard Cast Steel Stainless Steel Flanged Lift 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.
Lift check valve is one type of check vlave whose disc slides along the centerline of the valve body. Pipeline check valve is a new type of valve that has small volume, light weight, good processing technology, and is one of the development directions of check valves. But the fluid resistance coefficient is slightly higher than that of a swing check valve.
