Magic Plastics 1" Union Check Valve 0823-10C

The “Smart” Check 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 any orientation. The valve is also available in a non-magnetic, ½ lb. Spring-Loaded version.
