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.
