Many thanks, Allen. I've just repaired three TRVs that I've been meaning to replace for years. The valve was stuck down in every case. Now, I suppose I ought to go and apply a drop of magic mist to all the others in the house Before They Stick.
The older danfos type do indeed pull out,not sure about the new ones and this allows the silicon greese or spray to lubricate all the pin ,I have never had a problem just pushing it back in again too seal but you do get water leaking out while the pin is out although usually not very much Cheers .
