How about:

\version "2.19.17"

val = 12

\layout {
    \context {
    \Staff
    \override InstrumentName.after-line-breaking =
    #(lambda (grob)
      (ly:grob-set-property! grob 'long-text
        (markup
          #:box ;; only for debugging, delete me
          #:hcenter-in val
          (ly:grob-property grob 'long-text))))
    }
}

   \new Staff
   \with { instrumentName = "Percussion" }
   { c''1 }
   \new Staff
   \with { instrumentName = "Violin" }
   { d''1 }
