I need to remove a radiator, dry line the wall then fit new diferent

My question is. Is it acceptable to use normal service valved and
leave them in the system?

Why drain twice? If your radiators have valves on both ends already
just close those and leave them attached to the pipe ends.

What I was thinking - even if the valves need moving when fitting th enew
radiator - it is only one drain down.
