From the pic you provided if I am looking at it right it looks as if you have shutoffs and drains on the returns but only zone valves on the supply's and no shutoffs.

If all you want to do is drain a zone for baseboard replacement close the ball valve on the return to that zone, remove the #1 wire on the zone valve (top wire) so even if someone turns your stat up by mistake it will not operate the ZV.

The ZV will act as a positive shutoff, stopping water from circulating up into the zone and then just open the drain to that zone and the water should drain out of the baseboard.

As long as the ZV and ball valve are good doing this will not effect the rest of the system and you can operate it as usual until you get done without rushing.

Hope this helps a little.

What do you mean by replacing "old baseboard elements"? What type baseboards? Usually when baseboards are shot, they are replaced altogether. Its "elements" that makes me wonder.
