5200 In-Line Pressure Vacuum Relief Valve

The model 5200 In-Line Pressure Vacuum Relief Valve maintains a tight seal until system pressure or vacuum exceed the set pressure of the valve. When overpressure occurs the weighted pallet lifts, breaking the seal between the seat and pallet, allowing vapors to pass through the valve orifice and relieving the pressure or vacuum buildup. The valve reseals upon relief and remains sealed.
