Emergency Vent Cover


Emergency Vent Cover

The series KSEP 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 KSEP emergency pressure relief vent provides pressure relief only.
Vacuum relief must be supplied by normal venting devices, or use our KSEV emergency pressure and vacuum relief vent covers.
When excessive pressure builds within the storage tank the KSEP 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.


The series KSEP 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 50mm W.C to a maximum of 700mmW.C
Sizes are 400, 450, 500 and 600mm with flange drilling according to ANSI 150lb or API650.
