APCO Sewage Air/Vacuum Valves (ASV)
Air/Vacuum valves allow large volumes of air to be exhausted from or admitted into a pipeline as it is being filled or drained. The elongated body of the Sewage Air/Vacuum Valve minimizes clogging by permitting use of a much longer float stem to prevent the sewage from fouling up the mechanism.
