General Description :
Combination air valves are normally installed at high points where air would
naturally rise ahead of the incoming liquid during filling and collect during
operation and/or where negative pressure first occurs during draining.
The large (air & vacuum) and the small (air release) orifices are both open
during filling with the majority of the air is passes through the large orifice.
The rate at which air is discharged is a function of the differential pressure
across the air & vacuum valve.
During filling, incoming water compresses the air in the “empty” pipe until
the pressure differential across the air valve is sufficient that air is discharged
at the same volumetric rate as water is entering the pipe.
After all the air has been purged, liquid enters the valve and lifts the floats
and closes both orifices.
While the large orifice remains closed, the small orifice reopens as necessary
to release any air that collects in the valve after it has closed. Should the internal
pressure fall below atmospheric, both orifices open to allow air to flow through
the valve into the system at the same volumetric rate at which the liquid is
draining thus avoiding critical vacuum and damage to the pipe.
