Each valve has two sets of holes, which direct the air flow either directly through, or when the valve is pressed, through additional tubing. By making the entire instrument slightly longer, it lowers the pitch.

Which brass instrument is built with rotary valves?

I'm no brass instrument, but rotary valves are used for several instruments. French horns all seem to have them. They're pretty common on tubas as well.
