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.

The series KSEV 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 / vacuum setting range is from a minimum of 25/-25mmW.C to a maximum of 700/-700mmW.C
Sizes are 400, 450, 500 and 600mm with flange drilling according to ANSI 150lb or API650.
