On an F tuba, you are always going to need five valves to get the low F# (a semitone above the fundamental) in tune. Just as a bass trombone needs two triggers to get it low B (a semitone above it fundamental) in tune.
A main tuning slide trigger would need to have a hell of a lot of throw to get the low F# in tune on a four valve f tuba.
