Matthews, N.C.-based Conbraco Industries Inc.’s spill-resistant vacuum breaker (SVB) prevents cross-connections without allowing a water spill. Designated the 4W-500 Series, this valve is designed to prevent contamination of the potable water supply due to back-siphonage. It is ideally suited for continuous pressure, indoor applications where water spillage is undesirable. During normal flow conditions, the SVB’s check valve remains open and the atmospheric vent seals in the bonnet assembly.
