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

Designed to compliment the award - winning Aladdin Auto Vent range of de-aeration valves by offering a cartridge version; the Aladdin Hygroseal technology gives excellent functionality, yet is very cost efficient. The valves dispense 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. A backup failure safety mechanism is incorporated.

A 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.
