Hey Justin,
The 24mm valve piston refers to the piston in the LSC/HSC valve, where the adjustments are made. There is another piston in there, adjusting the LSC/HSC clickers meters the flow restriction through this piston, changing the amount of LSC/HSC the damper provides. The main piston on the end of the shaft is tuned using shims to give the correct damping characteristics for the frame/rider.
