Description
The Model 1200A pressure and vacuum relief valve is designed to protect your tank from damage caused by overpressure or excessive vacuum. Costly product evaporation losses due to normal tank "breathing" are considerably reduced. Because the Model 1200A retains toxic vapors, atmospheric pollution is minimized, helping to provide greater fire protection and safety.
Peripheral and central seat guides ensure reliable, repeatable performance.
A wide seat and an air-cushion seal keep leakage low long after the valve enters service.
The self-draining valve body and drip rings protect the seat surfaces from condensate and freezing, increasing operational reliability.
Fluoropolymer seat diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture.
