Axial flow nozzle check valve manufacturer, factory and supplier. The axial flow nozzle check valve also is a kind of non-slam or silent check valve, which is designed as a self-actualizing device and responds in a piping system to either pressure or flow changes. The main purpose of a non-slam axial flow nozzle check valve is to restrict or shut off the flow in the reverse flow direction. The important thing is that the normal position of a nozzle check valve is a valve close position with silent and non-slam closing action.

An axial flow nozzle check valve is a kind of silent check valve. The axial flow nozzle check valve is driven by the medium itself and automatically opens and closes the valve disc. Generally, it is used to prevent the backflow of fluid or gases. A flow check valve can be called a one-way valve, non-return valve, backflow valve, backstop valve, and back pressure valve. An axial flow check valve has been a popular industrial valve since 2008. This axial flow nozzle check valve has the function of the general check valve and is designed with a shock-absorbing spring, combined metal seat, and soft seat structure, which is easy for end-user maintenance on site.
 

The axial flow nozzle check valve adopts a particular sealing structure. Whether the downstream pressure is high or low, the valve is permanently closed tightly and has excellent shutoff performance. It overcomes the disadvantage of the lack of shutoff performance of the general check valve at low back pressure. The axial flow check valve that has a unique axial flow shuttle structure. It has the advantages of small flow resistance, significant flow coefficient, compact design, etc. It is the best valve for oil and gas gathering and transmission pipeline systems, especially for the outlet of oil transmission pumps.
