Brass automatic air vent valves
The air that usually forms inside a heating system must be promptly eliminated to avoid:
- corrosive phenomena;
- decreases in heat output and hydraulic efficiency;
- localized overheating;
- noise due to the passage of air bubbles;
- the danger of circulation pump failures.
The Varia bleed valves allow the complete evacuation of air automatically, but with the patented Varia version, thanks to the additional manual bleed, it is also possible:
- check the regular operation of the valve;
- speed up the evacuation of air in specific conditions (e.g., system filling).
