Structural principle
A check valve is a type of valve that automatically opens and closes its flap by relying on the flow of the medium itself, used to prevent the backflow of the medium. It is also known as a non-return valve, a one-way valve, a counter-flow valve, and a back pressure valve. A check valve is a type of automatic valve. Its main function is to prevent the backflow of the medium, prevent the reverse rotation of the pump and the driving motor, and release the medium in the container. Check valves can also be used on pipelines that supply auxiliary systems where the pressure may rise above the system pressure. Check valves can mainly be classified into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).
The H74W10- fan check valve is a thin check valve with a short structural size and a single disc design. Compared with the traditional swing check valve, this series of stainless steel valves has the advantages of no external leakage, can be installed at any position, has good sealing performance, small linear vibration, small pressure drop and zero seat ring wear. It is applicable to water supply and drainage systems, Roots blowers, petroleum, chemical, metallurgical and other industrial sectors, and is suitable for places with installation space restrictions.
