Just wondering if an electric valve can be put in the pipes that go to the
second floor to make it a separately controlled zone.

Thanks

You probably have to run another pipe to break off of the first floor,
otherwise the first floor would have to be calling for heat before the
second floor would get any. Not a cheap job but they do make zone valves for
steam systems
