401 and larger Model APCO Sewage Air & Vacuum
Valves are specifically designed for operation on
Sewage and Waste Media.
Air and Vacuum Valves are needed to vent large
volumes of air when the sewage line la filled and allow
air to re -enter when draining, to prevent vacuum or
column separation occurring. Sewage Air and Vacuum
Valves utilize two floats, each connected to a common
stem which Is guided thru a bushing,
The upper float shuts off instantaneously against the
seat, due to the impact zone and lifting force of the
much larger CONCAVE BOTTOM FLOAT *, as sewage
media enters the valve body.
Once closed, and pressurized, the Air & Vacuum will
not open to release air. It will open under negative
pressure allowing air to re -enter and prevent vacuum
to form In the line.
