Stainless steel vacuum breaker PVB10

Vacuum breaker in complete stainless steel construction. It is best suited on steam inlets to heat exchangers, jacketed kettles, liquid process lines, chilled water lines, boiler feed water lines and air coils, to admit air whenever vacuum condition is developed in the system. FEATURES: Works like a check valve and allows air to enter the steam or liquid system, however, steam or liquid escape is shut off. PVB10 is designed to allow air into condensing steam or liquid systems where creation of a vacuum would inhibit liquid drainage and decrease system performance and efficiency.
