TRV identification diy

[justinthyme97]

Could anyone please identify this brand of TRV?

I want to avoid draining down so just want to replace the head. I can close the valve with a commissioning cap but the TRV doesn't do that any more. I can't find any brand name but Myson, Wickes and Center heads (which I borrowed from around the house) don't quite match up...of course! It's about 15 yrs old.

Not one I’ve seen before, any markings on the top of the head?

No. Blank I'm afraid.

Underside if it helps.

It could be any then. The borrowed heads, are they close? If so could be m28 thread, in which case adapters can be had.

Any markings on the valve body?

The threads all seem to match and not much help on the valve body. DN15
