Sketch- Air Release, Degassing, & Venting Valves

 

Series DGV 

Automatic Degassing Valve - Vents trace amounts of gas continuously, as they occur and accumulate in the valve. Recommended for applications prone to outgassing, ozone processes, etc.

This is a normally open valve - vents in or out - increasing liquid pressure forces air/gas out.
Rising liquid lifts a natural polypropylene float, which acts on an armature and seal to close the valve bubble tight. When air or gas accumulates again, the float drops and the valve reopens. Liquid pressure forces the gas to be expelled, and then re-closes the valve. The process repeats over and over, automatically, as gas accumulates.

The valve has a very small orifice and is designed for trace amounts of gas. To expel large volumes of air such as at system start-up, see Series ARV above. If your application requires expulsion of a large amount of air, as well as periodic venting of smaller amounts, you may require both the Series ARV and Series DGV.

Series ARV

High Capacity Air Release Valve - Normally-open valve vents high volume of system air at start-up.
As liquid rises, a self-guided poppet closes the valve. The valve will close with liquid present at 0 psi, and will close bubble-tight under pressure.

Once the valve closes, it will not re-open until liquid is drained from the system and pressure drops. For continuous venting as needed, see Series DGV below. If your application requires expulsion of a large amount of air, as well as periodic venting of smaller amounts, you may require both the Series ARV and Series DGV.
