Axial-flow check valve
The Axial flow check valve is a new concept series. The internal flow passage of the valve adopts a streamlined design and is provided with a fluid guide. it is mainly used at the outlet of the water pump or other places to prevent liquid backflow, which can effectively prevent water hammer impact and noise caused by the liquid backflow of the ordinary check valve. It is silent and has good sealing performance.
