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 old 28mm 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.
