HV30 Self Bleeding Radiator Valve in Chorme, pack of one valve. The HV30 works in exactly the same way and has identical operating characteristics as the HV30C, with the only difference being that the operating mechanism for the valve is directly assembled into the housing, not in a cartridge. The advantage is that there are considerably fewer components and therefore it is less costly to manufacture; the disadvantage is that after 5 years, if the radiator starts to collect gas, the whole valve would have to be replaced. Aladdin valves automatically de-aerate the system, once fitted they keep the central heating system topped up with water and operating at full efficiency keeping your radiators hot. The HV30 fits all 1/2″ BSP radiators and come with a 3 year manufacturers warranty. The valves are fully automatic, requiring no manual adjustment and will not leak in the enlikely event of failure. They are very easy to install and you do not need to drain your system to do so.
