What is a DIN Swing Check Valve?

A DIN Swing Check Valve is a fluid device designed for one-way flow of liquids or gases. It has a disc that swings on a hinge, opens to allow fluid to flow in, and then closes to prevent backflow. Swing Check Valves are designed in a variety of sizes with different features to suit specific types of applications.
