Solenoid Energization Identity
Blank - Standard arrangement for ANSI
B93.9 (i.e. energize solenoid A to
follow flow P to A).
V - Solenoid identification determined
by position of solenoid (i.e. solenoid A
at port A end/solenoid B at port B end).
Note
4 and 8 type spools are always V.
Solenoid energization identity is
independent of mainstage porting.
