• Reduces replacement costs – no internal or external metal components; ideal for aggressive environments.
• Placed at the high point of a piping system, this innovative valve will vent gas as it occurs. A unique float/actuating lever allows the vent orifice to open when gas is present. After gas vents, liquid forces the vent to close. Whenever gas accumulates, the valve will re-open until the gas is vented.
• All-plastic construction designed for sodium hypochlorite, ozone systems, or any liquids prone to outgassing.
• Series DGV is designed for systems that continuously generate trace amounts of gasses. For system start-up requiring rapid expulsion of larger volume of air or gasses, see Series ARV.
