The model KSBBJ and KSBJS pressure vacuum valves with steam jacket are an advanced design for vent to atmosphere applications. Designed, manufactured and tested according to the API 2000 code, these valves utilize the latest technologies to provide protection against positive or vacuum over pressure and prevent air intake, evaporative losses of product and help to contain odorous and potentially explosive vapours.
Some special fluid or gases are sublimated at room temperature. The safety of tank is kept by the supply of external heat and the normal operation of valve disc (pallet) for venting.
