20mm Brass swing check valve – non return valve

A swing check valve is a type of non return valve that uses a simple design to achieve the one-way flow of a liquid. The brass non return valve uses a disk that swings on a hinge. When fluid flows in the correction direction it pushes the disk open to allow fluid to flow in the correct direction. When the flow stops the disk closes to prevent back flow. Swing check valves are designed in a variety of sizes with different features to suit specific application types.
