Product Description

 

Products Description

The swing check valve, also known as a one-way valve or check valve, is used to prevent the medium in the pipeline from flowing back. 

A valve that relies on the flow and force of the medium to open or close itself, in order to prevent the medium from flowing back, is called a check valve. 

Check valves belong to the automatic valve category and are mainly used in pipelines with unidirectional flow of media.

They only allow media to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in pipelines.

Check valves can also be used to supply pipelines to auxiliary systems where the pressure may rise above the system pressure. Check valves can be mainly divided into swing check valves (rotating according to the center of gravity) and lift check valves (moving along the axis).

 

Usually, this type of valve operates automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the valve seat is cut off by the fluid pressure and the self closing of the valve disc, which acts on the valve seat.
