It's a valve that normally is in the "on" position. That is, when in the non-depressed state, the air goes through the tuning slide for that valve. When depressed, it's straight-through.

So, for a hypothetical example, you could have a CC tuba with three valves (not that you would normally anyway), where valves 1 and 2 function normally, but valve 3 raises the pitch by a minor third instead of lowering it by the same amount. So fingerings would go something like this:

Low A: 12
A# 1
B 2
C -
C# 13
D 23
D# 3
E 12
F 1
F# 2
G --
G# 13

...and so on. The advantage is that for most notes, there are no abrupt jumps in partials when proceeding chromatically. The disadvantage is that you do have somewhat more cylindrical tubing in the loop at most times and that intonation might not be as good as you'd like because the 1st slide in 1+3 combinations is entirely too long. It might be fun to take a junker eefer and set it up as a CC with an ascending 3rd valve just to see how bad it would be.

This probably works for French horns because basically nothing is naturally in tune on those things and the minor matter of intonation is left to the skills of the player.
