1200A - Pressure/Vacuum Relief Valve

Model 1200A is designed to vent to atmosphere to protect your tank from damage created by over-pressure 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.
