Micro Automatic Radiator Bleed Valve (6mm)
Micro Auto Vents are used to vent unwanted air from a radiator. Air build up occurs over a period of time and collects in high spots of a heating system, (usually a radiator and in most cases, the first radiator after the central heating pump). Automatic bleed valves vent unwanted air from the radiator automatically. A micro auto vents has a life of about 3 years and then needs to be replaced.
