A Non-Return Valve Swing Type Class 150, 300, 600, 900 & 1500 only permits one direction of flow through a pipe and closes automatically when the direction of the stream changes. Home water systems utilize non-return valves to prevent backflow, while heating and cooling systems use mixing loops to maintain proper performance
