While the head removes easily, it does not appear to come apart in a
non-destructive way, I have looked very closly.

As I mentioned in my first post, if I only just engage the threads of
the head onto the body of the valve it works OK, but as I start "doing
up" the nut (knurled ring) the head is pulled down and flow reduced.
Then, as everything gets warm (TRV head in proximity of rad) flow is
shut off but before the room is warm enough.

While I could leave the head only partly engaged with the threads, I
I don't like that idea, all it would take is someone who doesn't know
to give it a tweak and they've got a TRV in their hands!

Mine have removable limit stops - which if removed allow the knob to
make an extra turn.
