Product details

Swing Check Valve

A swing check valve, also known as a one-way valve or check valve, is designed to prevent the backflow of medium in the pipeline. The valve that relies on the flow and force of the medium to open or close itself, in order to prevent the backflow of the medium, is called a check valve. Check valves belong to the automatic valve category and are mainly used in pipelines with unidirectional flow of medium. They only allow medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in pipelines.
