Emergency Vent Cover
According to API 2000 Code : The series KSESV is designed to provide emergency pressure vacuum relief for storage tanks when exposed to overpressures and overvacuum 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.
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 700mmW.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.
