Vent Operation :

The KSES emergency pressure relief vent provides pressure and vacuum relief..
When excessive pressure builds within the storage tank the KSESV series emergency pressure relief vent begin to open at a predetermined set pressure relieving excessive pressure.
When the overpressure has dissipated the cover reseat onto the base.

Construction :

The series KSESV is available in several materials that are corrosion resistant to most petroleum product applications.
See Standard material of construction table for available material.
Predetermined pressure setting range is from a minimum of 700mm W.C to a maximum of 7,000mmW.C and vacuum setting range is from a minimum of -20 mmW.C to maximum of
-700 mmW.C.
Sizes are 400, 450, 500 and 600mm with flange drilling according to ANSI 150lb or API650.
