The Barberi® P58 automatic air vents allow to remove air from the systems without manual operations. They are normally installed in radiator heating systems. Thanks to the air removal, they are allowed a longer system life, avoiding corrosion due to component oxidation, a higher thermal efficiency of heating emitters, a better working and safety for pumps. P58 series valves are particularly suitable for a direct installation on radiators and feature a clockwise or anti-clockwise thread.
