If the old ones were compression, you can just unscrew the large nut on the 
half inch pipe and thread it on to the new shut off.  Good idea to use pipe 
dope on the threads.  If the old is soldered on, you'll need a torch and 
usually need to trim it back just a little because of the solder that runs to 
the bottom of the joint and tends to stay on the pipe.  We're only talking a 
half inch or so.

    Scott,

  You said that you ran around your house replacing all the shut-offs with 
  the ball valves. How did you remove the old valves? Did you heat them 
  and pull them apart? Or did you cut them off and hope for enough slack? 
  Or, were the old one's compression fittings also and you were able to pry 
  them apart?

  Just curious.
