Pressure/Vacuum Relief Valve:
Model 1200A is designed to protect your tank from damage created by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the Model 1200A retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety.

Special Features:

Model 1200A offers Groth’s special “cushioned air” seating. Superior performing fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture. The Model 1200A has a self draining housing body and drip rings to protect seating surfaces from condensate and freezing. This design also avoids dangerous pressure or vacuum
buildup due to binding or clogging of the valve. Buna-N, FKM and other seating diaphragms can be provided when required. To insure the proper alignment of seating surfaces, there is peripheral guiding and a center stabilizing system.
