Air vent
Description
Ordering
Air vent valve
Picture
Automatic Air vent valves are installed in heating
systems to release air trapped in pipes. Medium
(water, glycol mixture) pumped through the
system pushes initial air inside pipes into the
Air vent. The flow stays in a lower part of the air
vent, allowing the valve to remain open and
continuously discharge air.
