    The fifth valve is there to (usually) lower the pitch by another whole tone to work with the fourth valve to improve tuning and intonation. More commonly found on F and CC tubas in modern design and construction.

    Think it has something to do with being none compensating. and the 5th valve helps with tuning on lower notes.

    It also depends on what sort of 5th valve you have. On a C I used to have I could change the length of the slide which mean it could either be lowered by a 2nd or a minor 3rd.
