VAG GA Industries - Model Figure 930 -Air & Vacuum Valve for Water

VAG GA Industries Figure 930 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 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 its simple construction ensures dependable, long-term operation.
