How to remove thermostatic value cover

[doylekm]

I have one cold radiator and I suspect the value pin is stuck but I can't see how to remove the thermosatic value cover to get to it. Its a Danfoss make and has some sort of spring mechanism which keeps it in place. I've tried twisting, pulling in various ways but cannot see how to remove it. There's no holding screw as far as I can see (but it's a bit inaccessible). I'm worried I'm going to break it if I continue wrestling with it. Does anyone know if there is a particular way to remove it?

look closely the black bit is in two halves hold the top bit and twist the bottom bit

Thanks for the suggestion, but I suspect the model I have may be different. It has a black top, a white outer piece which adjusts the temperature, and black inner construction. The white piece seems to have some spring mechanism which allow sit to be pulled a little away from direction of the radiator (it is mounted horizontally) but I can't find a way of releasing it.

Sounds like you might have one of the new snap on type. (no doubt designed to make life miserable for all who encounter it)

try reading page two of these instructions
