De-aeration valves
for automatic air
bleeding of radiators
Aladdin Autovent radiator air bleeding valves are fully
automatic, requiring nomanual adjustment. The Hygroseal™
technology (patent pending) uses a ‘dual-seal positive valve
closure’ that eliminates leaks and extends the working life
of the valve. A backup safety mechanism closes off the
valve at the eventual end of its life. The valve can then
be re-activated with a new cartridge, without draining the
radiator.
Autovent valves, which are guaranteed in operation for five
years, are made of chromed brass and can work at any
angle, designed to fit both panel and towel radiators. The
HV30C and Micro valves are BSRIA approved.
The valves can save plumbers considerable time on
installations, with 1 or 2 hours often saved on a typical
job. Call backs by the customer are greatly reduced, as no
return visit to bleed radiators is required.
The fact that Autovent valves do not need bleeding by
the end customer is especially important for managed
properties, commercial offices and government
organisations, as well as private homes. Efficient running
of the radiators also ensures optimum operation of the
boiler, avoids unnecessary corrosion and extends the life
of system components.
