air vent valves
Air trapped in radiators, manifolds or a solar circuit causes noise, reduces heat transfer and encourages corrosion, so it needs to be released from the system continuously. The range includes automatic air vents with or without a check valve, angled, hygroscopic and nickel-plated versions from 1/4" to 1", manual vents and a type for solar systems.

Automatic Air Vent Valves
Automatic air vent valves make it possible to eliminate residual air from heating systems without the need for manual intervention. They remove unwanted effects that can affect the service life and function of the system, such as corrosion of the equipment caused by the presence of oxygen.
Frequently Asked Questions
- What is the difference between an automatic and a manual air vent valve? An automatic valve vents the system continuously without operator intervention, while a manual one is opened with a key as needed – in practice, both types are often combined at different points of the distribution system.
- Where is the air vent valve installed in a system? At the highest points of the distribution system and at devices where air naturally accumulates, for example at the top of risers, at radiators or at manifolds.
- Is an air vent valve suitable for solar systems too? Yes, variants specifically designed for solar systems are also available, which withstand the higher operating temperatures of the collector circuit.
