Marketing InformationThe 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 lb/sq-in, 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, 1/2 lb spring-loaded version. Available in 1/2 - 3 in IPS sizes. All Smart Check valves are also available as a swing-check, without spring.
