The swing check valve, also known as a non-return valve, is designed to prevent backflow of fluid in pipelines. It ensures one-way flow of the medium, allowing it to move in only one direction to prevent accidents. Typically, these valves are installed horizontally in pipelines to optimize their functionality.
