GA Industries
VAG GA Industries Figures 959-T Combination Air Valves are 'triple function' valves and consist of an air release valve factory piped to an air & vacuum valve.They 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 also release air that accumulates in the valve while the system is operational.And, 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.
The Figure 959 consists of a short body air release valve and a short body air & vacuum valve and is idea for shallow cover installations.Figure 959L provides a larger orifice for faster release air and gas on systems operating at 75 PSI or lower.
Figure 959F-T includes optional 'back flushing attachments' to facilitate cleaning sludge and debris from the valve
