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.

Quick and Competitive

Video and detailed product information page was very informative, so I knew it was the product I needed. Best price I could find online, and arrived the day after ordering. ( 5 Jan 2018, 17:16)


Ordered 2 for my radiators. I know nothing about DIY and easy as the installation is I was a little apprehensive. That is until I watched the brilliant video instructions - clear and gave me all the confidence I needed to do it myself! Will be getting another shortly and definitely recommend. Quick and efficient service. Regular email updates on order. Just 1st class service really. Parts with me in 2 days and that’s with Christmas post. Thank you (28 Dec 2017, 22:21)
