Vacuum Breakers

Vacuum breaker - Provide venting in the pipe line to prevent siphoning effect / on the tank to prevent tank from collapse due to vacuum effect. The Plast-O-Matic VBM Vacuum Breakers have only one moving part – the patented self-sealing diaphragm, and this provides both design simplicity and maximum operating dependability. This normally-closed design seals in the identical location every time producing a very dependable, long-life seal. Series VBS Vacuum Breakers duplicate this function by using a corrosion resistant PFA encapsulated spring which acts on a poppet seal that neither sticks nor chatters. Maximum working pressure is 100 PSI @ 75°F (6,9 bar @ 24°C). Spring material (non-wetted) is 316 stainless steel.
