Reduced Varia valve with bubble-breaker, automatic air vent valve in brass.

The air that normally forms inside a heating system must be promptly eliminated to avoid:
- corrosive phenomena
- reduced thermal output and hydraulic efficiency
- localised overheating
- noise due to the passage of air bubbles
- risk of circulating pump faults

Varia air vent valves allow the complete, automatic evacuation of the air, but in the patented version, thanks to the additional manual vent, it is also possible to:
- check the regular operation of the valve
- more rapidly evacuate the air in certain situations (e.g. system filling)
