H76W Double Disc Wafer Check Valve

Product Description:

A butterfly check valve is a type of valve that automatically opens and closes the valve disc based on the flow of the medium itself, used to prevent the backflow of the medium. It is also known as a non-return valve, one-way valve, reverse flow valve, or backpressure valve. Check valves are a type of automatic valve, primarily functioning to prevent medium backflow, avoid reverse rotation of pumps and drive motors, and release medium from containers. Check valves can also be used in pipelines that supply auxiliary systems where the pressure may rise above the system pressure.
