Cartridge Valve Identification
NOTE: When troubleshooting hydraulic problems, keep
in mind that is possible for some cartridge valves to be
installed in the wrong ports, causing the system to
malfunction.
Solenoid valves in valve block must not be interchanged
b
etween ports, with the following exceptions:
S1 and S2 are the same design and can be inter-
changed (Fig. 79).
S3, S4 and S5 are the same design and can be
interchanged (Fig. 80).
S7, S8 and S9 are the same design and can be
interchanged (Fig. 82).
