A swing check valve is a simple device designed for the one-way flow of a liquid or gas. It has a disc that swings on a hinge, opening to allow fluid to flow in, then closing to prevent backflow. Swing check valves are designed in a variety of sizes with different features to suit specific application types.

When pressure changes in the piping cause flow reversal, check valves to protect pumps and other equipment from damage caused by backflow. They are used in a wide variety of applications for flow control including, line isolation, priming pumps, media injection, maintaining head pressure, and many others.
