Valve noise? Disturbance of airflow through port as valve is moving? Any other theories? Try a different horn. Are you using a rotary or piston tuba?
Pulsing of air should be fairly easy to diagnose. Buzz a legato phrase on the mouthpiece, keeping the airflow constant, then play it exactly the same way.
Enlist the help of someone with good ears and brass skills.
