The Model 8800A Pressure/Vacuum Relief Valve offers Groth’s special “cushioned air” seating. Superior performing fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture. Self draining housings and drip rings protect seating surfaces from condensate and freezing.
The Groth Model 8800A is a combination of the 1200A Pressure Vacuum Relief Valve and Groth Model 7618 Flame Arrester. The superior Buna-N seating diaphragms are standard on the valve to insure extra tight sealing to prevent sludge vapors escaping. Self draining housing body and drip rings protect seating surface from condensate and freezing. The 1200/7618 helps protect your tank from damage created by overpressure or excessive vacuum, at the same time it provides protection from externally caused sources of heat and ignition. The result is reduced emissions level and increased fire protection and safety.
