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.
