zDifferential circuit can be easily config-
ured at P
→
B by attaching OC-G**-A*
above the OC-G**-AP* on the sub-
plate. (See the figure to the right.)
xNote that a sub plate and installa-
tion bolts are not included. See
pages D-90 through D-95 if these
items are required.
c04 series modular valves do not
have an L (DR
2) drain port, so they
cannot be used in combination with
pressure center type solenoid
valves (D).
