Replacement head for Myson TRV 2 WAY thermostatic radiator valve (head only - no valve included).

This contract head is interchangeable with the standard Myson thermostatic head (which looks the same, but has red markings and a white bottom section).


Faulty Myson TRV head compared to a good one

Myson TRV heads are normally very good and last for many years, though one failure that can occur is an internal fault that causes the centre pin to be permanently stuck in the out position. This failure results in the valve not working and a cold radiator. The picture above shows two heads, a faulty one on the left and a good one on the right.

TRV 2 Way valve heads made between 1997 and 2012 had a symbol like the greek letter PI. This head, with the EN215 keymark symbol is a direct replacement.

The metal lock ring has a M30 / 30mm x 1.5mm metric thread. Myson has used this thread for a long time, though very old (pre 1997) Myson valves used a smaller 28mm x 1.5mm thread.

The picture below shows what the very old (pre 1997) thermostatic heads with M28 threads looked like. If you need to replace one of these you'll have to buy a new head and an adaptor (available in our store).

No nonsense, simple to order and pay for, arrived really quickly, the images showing "faulty" or "good" were really helpful, when highlighting where the problem was occurring with the cold rads ThanksJohn (29 Oct 2020, 15:42)

So easy!

Delivered faster than expected and was really easy to swap over. The video and photos of faulty and good really helped, I'm not a plumber - just simply unscrewed the old faulty one and replaced with new one. Voila! Hot radiator now. Thank you. Straight swap - no issues.Yvonne (22 Oct 2019, 17:59)
