A Check Valve, also known as a non-return Valve or a check valve, is a valve used to control the one-way flow of fluid. When the fluid flows in one direction, the check valve allows the fluid to pass through, but when the fluid tries to flow in the opposite direction, the check valve automatically closes, preventing the fluid from flowing back.
 
Check valves usually consist of a body, a valve cover, a valve spring, and a spool. When the fluid flows in one direction, the spool will be pushed away by the fluid, causing the valve to open. But when the fluid tries to flow in the opposite direction, the spool is pushed back by the valve spring, causing the valve to close.
 
Check valves are widely used in a variety of industries, including petroleum, chemical, tap water, sewage treatment, heating and air conditioning systems. They prevent fluid backflow, reduce pressure loss in the pipeline and maintain the stability of the pipeline.

A check valve is a type of valve used to control the direction and flow of fluid in a pipeline. It can prevent the reverse flow of fluid, also known as a non return valve, reverse valve, or backflow valve. A check valve usually consists of a valve body, valve cover, valve disc, spring, and sealing ring. When the fluid flows normally in the pipeline, the valve disc opens and the fluid can freely pass through. When the fluid flows in the opposite direction, the valve disc will automatically close, preventing the fluid from flowing in the opposite direction. Check valves are widely used in industries such as water supply, sewage, petroleum, chemical, and power.
