Productgroup: Air Valves
VAG GA Industries Figure 930-T 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.
Figure 930-T Air & Vacuum Valves are typically installed at system high points where air naturally rises during filling and vacuum first forms during draining.
The valve only has one moving part and it’s simple construction ensures dependable, long term operation.
