VAG GA Industries Figures 927 and 927L automatically and efficiently release air and sewer gas that have collected in the valve while under pressure and operational.Typically installed at high points where air and gas naturally collect, the valve opens when sufficient air and gas has accumulated in the valve and closes tightly after the air and gas has been released. __These 'high capacity' valves have a larger venting orifice than the standard Figure 925 or 929 air release valves and can release air and gas at a faster rate.They are recommended for systems where the necessary air venting rate exceeds that of a standard valve. __Figures 927F and 927LF include optional 'back flushing attachments' to facilitate cleaning sludge and debris from the valve.
