If you have patience, a Dremel, and some abrasive slitting wheels for it
you could try carefully slicing one or both sides of the female threaded
part of the valve to the point where application of a large screwdriver
in the slot you make may spring it open enough to break the corrosion bond.
Even if you slice a litlle bit of a line up the side of the male pipe
threads, chances are good that a new valve will seal to it if you use
teflon tape AND joint compound when screwing it on.
If the threads on the pipe turn out to be mostly rotted off when you get
the valve off then the depth of the doo-doo you're in will have
increased significantly.
Good Luck. Let us know how you make out.
