Radiator TRV identification

[Tommo_UK]

Hi all, can anyone identify this radiator TRV please? It’s become faulty and I’d like to just replace the head but the Drayton ones don’t fit!
Many thanks in advance.

Don't recognise it I'm afraid, but any TRV head with an M30 thread should fit

Thanks for the reply. I’ve tried a Drayton RT212 which has a M30 thread and unfortunately that doesn’t fit.

Too big or too small?

When I got eQ-3 electronic heads they came with a pack so it can fit many makes, at £10 standard and £15 bluetooth can't see the point in not using electronic.

It’s not the size as much. The old head locates onto an 8 sided nut, the new ones onto a 6 sided nut.
