Automatic air vent, nickel-plated, with 1/2" external thread,
incl. shut-off valve with self-sealing seal and brass mandrel
for quick replacement of the automatic vent valve.
The shut-off valve prevents liquid from escaping from the system.

DESIGNATION
Automatic air vents are used in heating and cooling systems to remove air
that is trapped in the circuits during charging or that has formed during normal operation.
This series of valves is characterized by its excellent venting capacity and is equipped with
a protective cap to prevent hot liquid from escaping suddenly.

Operating principle:
The presence of air in the system reduces the water level in the relief valve,
resulting in the lowering of the float and the opening of the gas release device.
Otherwise, if there is no air in the circuit, the water in the safety valve will keep the float in such a position,
that the gas discharge remains closed.


Eliminating the air in the circuits avoids problems such as noise in the system and wear of its components,
to ensure better performance of the radiating ports, resulting in a consequent reduction in operational costs

ADVANTAGES/STRENGTHS
- Automatic vent operation.
- Maximum delivery pressure 4 bar.
- Guarantees better performance of the system with a consequent reduction in management costs.
- Avoids problems with system noise and component wear.
- High ventilation performance.
- Equipped with a protective cap against sudden hot liquid spills.
