Solenoid Operated Directional Valves Product Catalog V-VLDI-MC011-E September 2008
Functional
Symbols
Spool types shown repre-
sent the highest proportion
of market requirements. For
other spool functions that may
be required, consult your
Eaton sales representative.
Solenoids identified to U.S.
standards
Functional symbols related to
solenoid identity “A” and/or
“B” according to NFPA/ANSI
standards, i.e. energizing
solenoid “A” gives flow P to
A, solenoid “B” gives flow P
to B (as applicable).

SolEnoid typE SolEnoid
B All A
except

A “8” only B
For valves with type “8”spools,
solenoid identity to U.S.
convention is the same as for
European convention.
Solenoids identified to
European standards
(specify “V” in model code)
Functional symbols related
to solenoid identity “A” and/
or “B” according to European
convention i.e. solenoid “A”
adjacent to “A” port, solenoid
“B” adjacent to “B” port of
valve.

tion, refer to Performance
