HV30 Aladdin Self Bleeding Automatic Radiator Valve 1/2" BSP Single Valve

Product Information

Once you’ve finished bleeding the radiator, you can go and repeat the procedure on all the other radiators in your home that require bleeding. If it’s the large nut that comes on most modern radiators, then this will have a rubber O-ring seal, in which case you should replace it if you find the correct size.

Perform a " flush and fill." After you've bled a car's radiator, it can be a good idea to add new coolant. Trapped air can artificially inflate a car's coolant reading - you may be running low on coolant without having realized it. Drain old coolant from your system and add fresh coolant, observing any special instruction in your owner's manual. Below are general instructions for replacing your car's coolant: [17] X Research source There is also a circular ½” BSP valve (Antrax) which has 3 side ports that allow a U key to be used to rotate the valve and screw in/unscrew from a radiator. Before starting any maintenance work on your heating system, it is always important to turn the heating off and allow the radiators to cool down to prevent burning yourself. Step 2: Isolate the radiator This guide should answer most questions asked regarding the Aladdin Autovents. 1) How do I find the correct sized Aladdin Autovent valve for my radiator? You can also go for a self bleed automatic bleed valve which does the work for you for only a couple of quid more.There might be a cover over the bleed valve that you need to remove to access it. These can be pulled off or sometimes need to be screwed off. On a Closed, pressurised system: After the air absorbed in the water has separated, the best early indicator of a leak is a drop in pressure of the system. An Autovent should, if anything, lead to a faster drop in pressure so an even earlier indication of a leak. Yes, provided the temperature of the piping allows the valve to operate at 35°C for the Hygroseal™ Autovents. 14) Can the valves work on negative pressure systems?

How To Bleed a Radiator Summary The HV30C self-bleeding radiator valves save energy, keep radiators hot-to-top, reduce corrosion and system noise and dispense with the use of radiator keys. Remove the bleed valve from the radiator using an adjustable spanner or the bleed screw with a bleed key Radiator bleed valves are cheap so if you can get the correct size easily then you should replace it when the old one leaks. Replacing The RadiatorThe standard radiator tapping size for Panel Radiators and Towel Radiators (80% of market) is the ½” BSP tapping. Only approximately halfway up the radiator can the hot water reach due to air rising and being caught. This is incredibly inefficient and may help to explain why you’ve been seeing cold patches or draughts in your house, or just wondering why a room seems a bit cool.

This is a guide on how to manually bleed your car’s cooling system without any special tools. Remember always to be careful when it comes to car cooling systems because it will reach boiling temperatures. Depending on the model and age of your radiators, you can find many different types of bleed valves. Most standard size manual radiator bleed valves are ½”. However, they are also available in ¼” and ⅜” thread sizes. So make sure to measure your current bleed valve to help you find the correct replacement. Automatic valves are used to release trapped air as it collects. They are not a substitute for bleeding a system manually when it is first filled during commissioning, nor for remedial bleeding if the system becomes choked with trapped air. In those cases, individual bleed screws on each radiator, or high pipe run, are opened manually. It is much easier to do this if you are two people, so make sure to bring a friend! Follow these steps to bleed the coolant system easily:

A working system should not generate further trapped gas. Air may be drawn in if there is a small leak, or dissolved air in make-up water may come out of solution, but this generally indicates a system leak if new water is needing to be added. The most likely cause of continual gas bleeding is hydrogen, rather than air. [2] If there is corrosion or rusting of internal metal components, this releases hydrogen gas. The appropriate cure here though is the use of a chemical inhibitor, rather than continual bleeding. [3]
