TOPSAFE Relief Valves

Model: KSBS

Pressure Vacuum Relief Valve Vent to Atmoshphere
According to API 2000 code, the pressure & vacuum relief valve of Model KSBS is designed, manufactured and tested.
Model KSBS, which is used for the protector of fluid storage tank, is composed of one body with the functions of pressure relief and vacuum relief.
This valve has function to intake the air under constant pressure during unloading, and to discharge the overpressure generated during pouring the fluid into storage tank.
This is the safe valve to control the deflation (vacuum) and inflation (pressure) of several storage tanks.
Size : 2" through 12"
Pressure setting: 22mmW.C to 50.000mmW.C
Vacuum setting : 22mmW.C to 50.000mmW.C
