** remove the valve completely, cut the pipe it was attached to where the hole is, & use a repair coupling to repair the pipe. **
I agree with removing the valve completely (hopefully to avoid the potential for future leaks) but why not just solder the remaining hole closed if it is mounted on a copper pipe?
BTW. The water in the pipe would have to be turned off first!
