Can anyone identify this TRV valve?

[johnpaulsmith]

Hi Everyone,

My first post here after lurking for a while, given the vast knowledge on the forum hopefully someone can help me.

I just moved into a new house and am fixing a few problems with the heating system. One of the radiators has a TRV valve body fitted, but no TRV control head on it; I would like to fit one. The rest of the house has Honeywell or Caleffi TRVs and those heads don't fit, although the screw thread is the same as the Honeywell. Can anyone identify this valve?

In case it helps, there is a date printed on the side, it was made in 2008.

Thanks,

J-P

is this valve in the same room as the wall thermostat?

No, there is actually no wall thermostat anywhere in the house (that's another job on the list). This valve is in the conservatory, so I can see why the previous owners would want it to be on a lot, but I would like to be able to control it to avoid wasting energy when we aren't using that room and on sunny days when it heats up quickly anyway.
