Edwards UTA Gas Valves

The AV5A and AV10K aluminum alloy air admittance valves (also called 'up to air' or vent valves) each have a control knob attached to a screw-actuated plunger sealed by a nitrile o-ring onto a seat in the valve body. The AV5A can mount on a pipeline or panel and connects to the vacuum system with Edwards couplings supplied with the valve. The AV10K mounts on a pipeline with a QF10 flange (also supplied with the valve).
