Cast Iron and Ductile Iron Valves manufacturers  Swing check valves are generally installed in pipes to prevent backflow. The check valve is basically a one-way valve whose flow runs freely in one way, but if the flow turns, the valve closes to protect the piping, other valves, pumps, etc. A swing check valve is mounted with a disc that swings on a hinge or shaft. The disc swings away from the seat to allow forward flow, and when the flow stops, the disc swings back to the seat to prevent reverse flow. The weight of the disc and return flow can affect the closure characteristics of the valve.
