Non self lapping brake valves like the M-19 (Qs) and the ME-23 (ABs, Ds, Lo-Vs and R-1/9s) have specific positions that require “fanning” of the brake valve between service and lap positions (lap bing a pneumatic holding position). SMEE equipment (and the Multis before them) had a self lapping feature in which braking effort is based on the position of the brake valve. |
