The model KSBG and KSGS pressure vacuum valves are an advanced design for pipe away 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.
These pressure vacuum valves maintain a tight seal until system pressure or vacuum exceeds the set pressure. The valves allow an intake of air under constant pressure during emptying, or discharge excessive over pressure during filling of the tanks. Flow curves are provided to help you select the proper valve size for venting requirements. In addition, KSPC’s applications engineers are always available to assist you. The KSBG is a weighted pallet model designed to handle pressure and vacuum with a minimum pressure of +/-20mmW.C and a maximum setting of + 700/-430 mmW.C The KSGS is a spring loaded model designed to handle pressure and vacuum with a minimum pressure of +700/-430mmW.C and a maximum setting of +/- 9,000mmW.C. High strength, one-body casting provide added structural integrity and durability. Body materials are available in Aluminium, Carbon Steel, 304SS and 316SS with various trims to suit individual requirements. Sizes range from 50mm through to 350mm with ANSI 150lb FF flanges as standard. (Different connections available on request).
