Model KSBBFI /BSFI, which is used for the protector of the fluid storage tank, is composed of one body with the functions of pressure relief, vacuum relief, and block the external repellent fire.
This consists of the flame arrester which blocks the external repellent fire, the function of discharge the overpressure developed during intake air to the storage tank, and the function of intake the air under constant pressure during unloading. And this is the safety valve to prevent the many kinds of storage tanks from deflation (vacuum), inflation ( pressure ), and fire.
The standard flame cell is suitable for NEC group D or IEC IIA gases, Cells for other gas groups are available as additional extras.
The KSBBFI 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 KSBSFI is a spring-loaded model designed to handle pressure and vacuum with a minimum pressure of +/-700mmW.C and a maximum setting of +/- 9,000mmW.C.
Body materials are available in Aluminium, Carbon Steel, 304SS and 316SS with various trims to suit individual requirements.
