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 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 designed to prevent medium backflow, avoid reverse rotation of pumps and drive motors, and release container media. Additionally, check valves can be used in pipelines that supply auxiliary systems where the pressure may exceed the system pressure.
