Tecno-Varia

Tecno-Varia, automatic vent valve with cover in plastic and anti-dirt air chamber.

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.

Tecno-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).
