KSBS TYPE PRESSURE VACUUM RELIEF VALVE

The model KSBB pressure vacuum valves are an advanced design for vent to atmosphere applications.
Designed manufactured and tested according to the API 2000 code,NPFA 30,ISO 28300 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.

INTRODUCTION
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.
The KSBS is a spring loaded model designed to handle pressure and vacuum with a minimum pressure of +/-700mmW.C and a maximum setting of +/- 7,000mmW.C.
High strength, one-body casting provide added structural integrity and durability.
Body materials are available in Aluminum, Carbon Steel, 304SS and 316SS with various trims to suit individual requirements.
Sizes range from 50mm through to 300mm with ANSI 150lb FF flanges as standard. (Different connections available on request).
