This depends whether you count all the slides, valves and springs etc. Simply, the tuba has a mouthpiece and the instrument. Otherwise, it has any number of slides, depending on make, same with the valves.
generally at least three. entry level tubas have the basic 3 valves - a half step lower, a full step lower, and a step and a half lower. more advanced tubas can have a fourth valve, which functions as a combination of the first and third valves, or two and a half steps lower. yet more advanced tubas can have a fifth or perhaps a sixth valve, which can be tuned to however many steps the player would like to have. more valves give the player more flexibility with regards to fingerings and intonation.
By definition, a valve is a device which switches a short piece of tubing in and out of the 'circuit' of a brass instrument. If the instrument, a Trombone, say, is 8' long, and the valve switches in an 8" piece of tubing, then the trombone will be 8'8" long with the valve actuated, and 8' long with the valve de-activated. There is another kind of 'valve', although it is actually more of a 'key': the spit-valve. This is a lever-activated hole cover, which, when opened, allows accumulated moisture to be drained from the tubing. You have to decide if the spit-valve counts as a valve for your purposes.
The trombone is a special case of the brass instrument family, in that it is played using a telescoping 'slide' to select the pitches. The standard tenor and alto trombone has no tube-switching valves at all, and one spit-valve.
The bass trombone often has a rotory valve (like the valves on the french horn) which switches in a considerable amount of tubing, switching the overall pitch by a fourth or fifth. In this case, the bass trombone has two valves, if you count the spit-valve as a valve.
There are also a variant family of trombones which use valves like the Trumpet, rather than the telescoping slide to select pitch-lengths. In this case, the valve trombone usually has three valves for switching tubing and the spit valve. A larger trombone, equivalent to the bass slide trombone, might also have one or two rotory valves for changing key as well, which would increase the number of valves to 5 or 6.
Bassoons don't use valves, they use finger holes, regular keys, and whisper keys.
Four, at least that's what the ones in my band have. I may be wrong
A trombone has no valve- only a slide. A valve trombone, or a marching trombone, though, have three valves.
Yes. There is an instrument called a "valve trombone", which basically looks like a trombone except that the slide doesn't move and there are three valves near the mouthpiece that look a lot like trumpet valves. In fact, trumpet players are often asked to play valve trombone in middle and high school jazz bands when no regular trombone players are around to fill the seat. This is possible because the fingerings on a valve trombone are exactly the same as those on a trumpet. Some trombone players, me included, find the valve trombone to have a somewhat flatter (tone, not pitch) sound than a traditional trombone. However, a good enough musician can easily achieve a beautiful sound on a valve trombone. Additionally, there is a horn called a marching trombone that also three valves. It is similar to a baritone, but the tubing length and bore sizes are closer to those of a trombone.
Assuming you're looking for how many valves you might find on a trombone...A regular, "straight" tenor trombone has no valves at all. The slide is used to change pitch.A "valve trombone" typically has three valves, similar to a trumpet's, to make changes in pitch.A trombone with an "F-trigger" employs a single (usually, rotary) valve.Many bass trombones use two rotary valves.
A trombone
Trombones come in three keys * Alto Trombone is in the key of E * Tenor Trombone is Bb * Bass Trombone is F They do not have keys that change the notes, the notes are changed by adjusting the length of the slide. *yes, there ARE keys on a trombone. it is for a different kind of trombone called a valve trombone. there are three keys. to change the notes, you would play with either more or less air
The trombone is known for it's slide.

A trumpet uses valves and is pitched higher than a trombone. The trombone uses a slide instead of valves, and is pitched between the trumpet and the tuba.

Yes, but there are trombones that do have valves. Bugles- no valves
Trombone. Or, since you specified bass a bass trombone.
A trombone
Trombones usually have zero valves. There's such a thing as a valve trombone, but that uses the standard three valve configuration, similar to a trumpet.

yes the trombone does
The trombone is the only instrument in the brass section with no keys or valves. It only has a slide.
