removal of ra 2000

[cosonic]

Hi.
How do I remove the few danfoss ra2000 valves , 1985 models from my radiators. I tried unscrewing the valves and i tried with Allen key in the small hole in the valve but no luck.
Pic beneath. Thanks

I would guess that the grub screw is just a locking mechanism and that once it is loosened you unscrew the black ribbed 'nut' from the valve itself. You might need some grips to help loosen it if it hasn't been touched in a long time.

But that is only a guess

Thank u for ur reply.
i dont know where that grub screw is located. i tried to loosen the valve from the ribbed space in it but i could only manage to turn it around less than a 1\10 of a cricle then i tried to pull the valve out with no luck!
any ideas?

Undo the grob and waggle off they are usually a bugger but will come off if you try hard enough!

I think he meant grub (grub screw), the small allen bolt in the neck of the valve.

thaks..but as i said earlier there is no screw in all of the 5 valves i have at home. just a very small cylinder
