商品スペック
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 provides a cost-effective solution to automatic radiator de-aeration.
Saves energy, keeps radiators hot-to-top, reduces corrosion and system noise, provides maintenance free system - dispenses with the need for radiator keys.
· Omni-directional operation for panel and towel type radiators
· Two stylish models for all known radiator tapping sizes
· Automatic safety feature
· Also works on negative pressure systems
· Replaceable cartridge
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.
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
