Breather valve
Pressure and vacuum relief breather valve is designed to protect low pressure storage tanks from excessive Pressure (or vacuum) created by thermal expansion (and contraction) and product movement into(out of) the tank and at the same time minizing costly product evaporation/loss.
Excesses in pressure or vacuum may also cause permanent deformation to the tank or unbalance a vapor recovery system.
The pressure and vacuum relief breather valve is installed on the storage tank roof. The valve may be mounted in onjunction with a KSFH or KSFI flame arrester to provide maximum protection against excessive pressure and vacuum while minizing accidental ignition of flammable product vapor from external sources.

According to API 2000 Code
The series KSES is designed to provide emergency pressure relief for storage tanks when exposed to overpressures that are not handled by standard tank vents.
These vents provide the capacity to meet API standard 2000 for emergency venting due to fire exposure when properly sized.
These covers also provide quick easy access for tank inspection and maintenance.

Vent Operation
The KSES emergency pressure relief vent provides pressure relief only.
Vacuum relief must be supplied by normal venting devices, or use our KSESV emergency pressure and vacuum relief vent covers.
When excessive pressure builds within the storage tank the KSES 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 KSES is available in several materials that are corrosion resistant to most petroleum product applications.
See Standard material of construction table for available material.
Predetermined setting range is from a minimum of 700mm W.C to a maximum of 7,000mmW.C
Sizes are 400, 450, 500 and 600mm with flange drilling according to ANSI 150lb or API650.
