You can only isolate the water to the radiator by turning off the radiator valves (turn clockwise) however the rad drainoff valve will still have water coming to it from the flow and returns so you'll need to drain the whole system in order to replace the drainoff valve.

Hope this helps. Regards.

3 options, drain the whole system down, plug the roof tank if open vented or freeze the pipes with a freezing kit. The 4th option is too call someone who knows what to do.
