Function
Automatic air vent valves are designed to remove the air that
accumulates in heating and air conditioning systems without the
need for manual intervention. This prevents harmful phenomena
that may compromise the life and the performance of the heating
system and which include:
- corrosion due to the oxygen;
- pockets of air trapped in the heating emitters;
- cavitation in the circulation pumps.
