Okay x2dz4l, I think I have an easy solution to your problem. First
you wanted to know about the types of valves used on different brands
of beer kegs. Here is a complete list:
http://kegman.net/b2c.html
It looks like Budweiser and Miller Lite use the "American SanKey".
Bass and Guiness use other valves. However, looking at the pictures
and using common sense, they all can be easily removed. They are
obviously removed every time a keg is cleaned and refilled. Here is a
detailed description of how to remove an American SanKey:
http://www.hbd.org/hbd/archive/4783.html#4783-9
Here we have an empty 1/2 barrel beer keg. This one just happens to be a
Miller keg. These are designed to hold 15 gallons of liquid, and a maximum
charge pressure of 60PSI.
And here is the only way in and out of the barrel, the neck. This fitting is
known as a "SanKey" in the industry.
The first step, and the most important is to blow off the charge pressure.
This can be done while still in the tapper, by turning off the C02 gas, and
opening the tap. At all times in this process, it cannot be stressed enough
that you must allways check to be sure that a charge has not built up in the
barrel. Things such as heat, will cause it to be recharged, or any small
residue of beer, that is still active can create pressure. I use a small
wooden dowl rod to press down on the ball valve in the center of the
fitting.
Now if you carefully examine the very top rim of the neck, you will see
stainless spring ring holding the stem assembly together
Note that the leading edge of the ring has a taper to allow for a removal
tool to get a start
I will use a metal awl, and a small straight blade screwdriver. The awl
first to get in behind the taper edge, pry the leading edge out, and then
use the screwdriver to work the ring out of the channel. It is quite easy to
do this, once the ring is started out.
HEY !! DID YOU REMEMBER TO BLEED THE PRESSURE BEFORE STARTING AFTER THIS
RING WITH A SHARP METAL TOOL ???
Keep your head clear of this anyway, while performing this operation, and
you may only lose a few fingers instead of your face
Well if you made it this far, you now have the ring out of the neck, and
here it is.
Note that there is a Keyway notch on the neck And also one on the stem
You need to rotate the stem in the neck until these keys line up, and you
will be able to lift out the stem
Out it comes, only this one piece
A close up view of the stem head valve assembly. There is an "O-ring", if
you need to replace this it must be a food grade "O-ring"
Well now you have it Clean your barrel with hot soapy water, rinse well in a
sanitizing solution. Do the same for the stem, and steel ring. and you are
ready to go !
It looks like the major concern is to bleed off the pressure before
opening the keg. Although this only covers the American SanKey I feel
pretty certain that it will be obvious how to remove the other valves.
From the pictures it looks like some unscrew and others use a
retaining ring.
After the valve is removed the beer can be siphoned into an
alternative container. I would think that 15.5 gallons could be
sipnoned in a few minutes with no labor required other than starting
the siphon.
This kit is stated to remove ALL valves:

In the instructions it says, "Things such as heat, will cause it to be
recharged, or any small
residue of beer, that is still active can create pressure. I use a small
wooden dowl (should be dowel) rod to press down on the ball valve in
the center of the fitting."
I would suggest that anything that will depress the ball valve could
be used. However, a soft material such as wood or plastic would
probably be best. You could attach the tapper, but that would just
take more time.
The reason that I suggest removing the valve is that you said that you
did not want to carbonate the keg. Also, if you use a standard keg
pump someone would have to continue pumping while the keg empties and
there would be lots of foam. You stated that you wanted a minimum of
manual labor. Siphoning is about as easy as it gets.
