Magic Smart Check Valve 2 inch Slip x Slip 0821-20C
The Smart Check is a patented innovation in Check Valves that provides you with reliable back-flow prevention without the inline restriction of a conventional check valve. With the use of high powered magnets, the Smart Check valve remains in the closed position to 2 PSI, opening fully when 2 lb. line pressure is exceeded. The Smart Check has a Spring-Loaded gate mechanism allowing the valve to be installed in virtually any orientation.
