The Check Valves permit flow in one direction only; the operation of the check valve is based on the movement of a small disc within the housing. The disc shifts within the housing as the pressure differential changes from forward to reverse. A flat surface on one side of the disc seals off the flow, while the other side allows flow to pass.
