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.


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 being shut off and a cold radiator. The picture above shows two heads, a faulty one on the left and a good one on the right.

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.

Great piece of kit, delivered very quickly.

If, like me, you need this to replace faulty older head, please note that the width of the collar on the original was 1/2 inch, this one is 3/8 inch, so I initially overtightened it, which just pushed the pin back in, stopping the flow. All good now and radiator doing what it is supposed to again. A huge Thank you to the Guys here for their very prompt service. (30 Jan 2019, 16:26)

Easy to order and very quick delivery. The valve head is easy to fit, and there is a good video on YouTube by Stevensons just in case you are a wee bit doubtful about how to do it! (19 Dec 2018, 09:14)
