The brasscraft for CPVC valves are nice because you can change them out if you need to. Just the "Compression" nut is behind the solvent welded stop. It has a replaceable 'compression' gasket at that point.
I also agree with Jeff, that you're much safer using a fine tooth saw to cut the pipe. Something like a japanese style saw or a metal cutting hacksaw blade that you're using the pull stroke to cut.
The tubing cutter to cut the valves is half is one good method I've seen. Way better than spinning them off anti clockwise and yanking them off.
