The only possibilities I found in the database for drawings are:

NW-B1041
NW-B41988

Based on the drawing description, neither is for the check valve itself, but they may be close enough to get a reference number on the drawing for the valve.

Many of N&W's early version locos (E2, M, M2,
K1, K2, K3, Z1) used a top mount double check valve where the pipes entered the
valve body from the rear, rather than the sides.
 
 
 Would anyone know who made this
valve? Has anyone ran across a drawing of this style of check valve in
the archives?
