INTRODUCTION
Leader Dual Plate Check Valves are automatic, quick-acting valve designed to prevent the reversal of flow in a piping system. The two valve discs, eccentrically embedded, have springs which force the valve to close in case no pressure is available. The pressure of the fluid passing through the system opens the valve discs, while any reversal of flow will close the valve discs. Closure is accomplished by the spring action and by back pressure.
