GA Industries Durovent Figures 929SS and 929SSL short body air release valves automatically and efficiently release air and sewage gas that have collected in the valve while under pressure and operational.Typically installed at high points where air and sewage gas naturally collect, the valve opens when sufficient air and sewage gas have accumulated in the valve and closes tightly after the air has been released.
Whether due to the fluid itself or ambient conditions, Durovent Wastewater Air Release Valves provide the ultimate in corrosion resistance since the body, cover, float, internal linkage, external fasteners and pipe plugs are all made from Type 316 stainless steel.Short body Durovent sewage air release valves are ideal in shallow cover installations that preclude the standard elongated body.
Figures 929SSF and 929SSLF include optional 'back flushing attachments' to facilitate cleaning sludge and debris from the valve.
