Replacement head for Myson TRV-2-WAY thermostatic radiator valve. Interchangeable with the standard Myson thermostatic head (which looks the same, but has red markings and a white bottom section).

Head only - no valve included.

Our video shows details of the head, including how to identify a faulty head and how to replace the head.

The metal lock ring has a 30mm x 1.5mm metric thread. Myson has used this thread for a long time, though very old Myson (we're not sure how old, probably pre 1997) valves used a smaller 28mm x 1.5mm thread. The older valves are not marked 2-Way and look completely different.

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

Myson TRV 2 Way valves

Absolutely first class service, ordered 4 units late Monday evening, auto accept directly. Tuesday by 09.30 confirmation order complete, in my hands by Royal Mail Wednesday mid day, and more competetive than the Am site. Well done will certainly recommend you to friends. The information video was first class also, no doubting faulty units after watching. Well done to everyone concerned. Thank you ( 8 Nov 2017, 15:45)

Myson TRV-2-replacement valve head

I found the website page about the valve very informative and helpful. The video on the page was a useful addition. This was able to convince me that this was the replacement valve that I required. Delivery was quick and part fitted successfully. ( 6 Oct 2017, 16:27)

Myson 2 way replacement head

I recently purchased three replacement heads as another one of mine had broken, after 18 years and the new ones are direct and identical replacements. The other 2 are spares. The cost and post seemed very competitive and it was nice to be thanked for placing the order and to receive an e mail confirming the very quick despatch. They arrived the next day so 10/10 (16 Oct 2014, 19:54)


I have regained control, many thanks (12 Jan 2014, 14:12)
