GA Industries Figure 959SS Durovent Dual Short Body Combination Air Valve exhausts air from pipelines and systems as they are being filled and then closes tight once the system is full and pressurized.It also releases air and sewage gas that accumulates in the valve while the system is operational.And, it automatically opens to admit air to limit vacuum formation when the pipeline or system is drained and/or a negative pressure occurs.
The Figure 959SS consists of a Figure 929SS short body air release valve and a Figure 939SS short body air & vacuum valve factory piped together.The valve’s all stainless steel construction provides corrosion resistance and its low profile is ideal for shallow cover installations
Figure 959SSF includes optional “back flushing attachments” to facilitate cleaning sludge and debris from the valve.
