The HV 30C Autovent with matching blanking plug fits standard 1/2" BSP radiator threads. This smart design in particular suits towel rails and designer radiators

The stylish and versatile range of Aladdin automatic radiator bleed valves with blanking plugs are a new breed in automatic radiator venting. The innovative Hygroseal™ technology (patent pending) with its long, leak-free life, provides a cost-effective solution to automatic radiator de-aeration.

By keeping radiators hot-to-the-top you get the maximum output from the radiator which heats your room faster and this saves energy. It also reduces corrosion, system noise and provides a maintenance free system - dispensing with the need for radiator keys.

The valves are fully automatic, requiring no manual adjustment, and will not leak in the unlikely event of failure as a backup failure safety mechanism is incorporated. Their one–way valve makes them suitable for use with radiators which can cycle into negative pressure, typically loft conversion radiators or on the suction side of the pump.

The innovative Hygroseal™ technology (patent pending) utilises a ‘dual-seal positive valve closure’ which provides an extended, leak-free life.

Simple Installation: Installing the valves is a simple DIY job that doesn’t require system draining. Once the valves are installed the changing of the cartridge is a ‘less than one minute’ operation.

So next time someone asks you 'How do I remove air in radiators?' - you'll be able to recommend this product to save them time and money
