VAG GA Air and Vacuum Valve Figure 930-DT, 930-UT, 930-DC, 930-UC for Clean Water

VAG GA Industries Figures 930-D and 930-U Air & Vacuum Valves efficiently vent air from pipelines and systems as they are being filled with water and then close tight once the system is full and pressurized. They automatically open to admit air to limit vacuum formation when the pipeline or system is drained and/or a negative pressure occurs in the valve.

Air & Vacuum Valves are typically installed at system high points where air naturally rises during filling and vacuum first forms during draining.

Figures 930-D and 930-U only have one moving part and such simple construction ensures dependable, long term operation.
