Series VBS Vacuum Breakers feature 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).

VBS Vacuum Breakers are available in Geon® PVC, Natural Polypropylene, Corzan® CPVC and Kynar® PVDF. No fasteners are used on Series VBS in 1½"" & 2"" sizes. External, non-wetted fasteners are used on Series VBS in 3"" & 4"" sizes and are 300 series stainless steel. The encapsulation is not ""adehered"" to the spring. It flexes independently of the spring and does not crack or flake the way coatings can. This encapsulation has been tested for over 1,000,000 cycles in laboratory conditions with no ill effects. Series VBS seals are EPDM or FKM (Viton).

Threaded connections are standard on all models. Socket ends, BSP threads, JIS and DIN connections are available on all sizes and materials. Outlet connection is shipped with standard dust cap. Cap is removable for applications where pipe connection is desired due to location, potential hazard, etc. The outlet connection is identical to the connection on the system side of the valve.
