I do all my own plumbing, but this one I'm going to let for the
professionals. My question is from curiosity rather than from a DIY
point of view.
If you need absolutely dry joints in order for solder to set, how do
plumbers solder a gate valve at the main shut-off? Are there any
secrets (don't laugh) like vacuuming water from the supply line (which
in this case is a private well)?
If it's a private well, it's pretty simple: turn power off to the pump and
drain the pressure tank.
If city water, there's normally a buried shutoff between the water main and
the meter. That's so the city can shut your water off if you don't pay your
bills. :-) And incidentally it makes it convenient for plumbers in situations
such as you describe.

And who wants to leave buttprints in the sands of time?
I've always seen flared valve fittings installed at the street
