Aladdin Automatic Radiator Valve - H50 Model

The Aladdin H50 was the first self bleeding radiator valve in the range. Designed to solve a long standing maintenance requirement, The H50 takes away the need to bleed your radiators.

This particular model fits all standard radiators with a horizontal 1/2”BSP tappings. With the installer in mind, the H50 incorporates speed-fit PTFE self-cutting threadseal, eliminating the requirement for PTFE tape to install the valve while providing a tamperproof fitting.

Because the Classic Aladdin Autovent is operated by radiator temperature fluctuation, the valve can be smaller than conventional type valves yet still provide positive shut-off. The secret of the Aladdin valve lies in its use of a bi-metallic disc which is used in conjunction with a miniature float - the patented 'dual-valve' design.

The minimum size of a conventional ‘float on a lever’ (miniature ballcock) valve is severely restricted. If the lever is shortened the float mass has to be increased; conversely, if the float mass is reduced lever length has to be increased to maintain true functionality.

Whereas the thermally activated disc in the Aladdin valve applies a powerful force to operate the valve enabling it to be miniaturised. The float design in the Classic Aladdin valve still allows automatic priming of a newly installed system (removing the requirement to individually bleed radiators when performing this task), but unlike any other float valve the Classic Aladdin has a unique, automatic safety cap that shuts down the valve (within 5 seconds) in the event of failure. The valve will then automatically reset itself, often continuing to operate successfully without any maintenance required (whereas a particle in the valve seat of a conventional valve will require manual cleaning).

PLEASE NOTE THAT THIS PRODUCT IS NO LONGER IN PRODUCTION AND AS A RESULT WE NO LONGER SELL THIS VERSION OF THE VALVE. THE HV30C HAS REPLACED THIS ONE.
