P, A, B, T can be drilled with max. Ø 30 mm in
deviation from standard ISO 4401-08-08-0-05.

Function, section
Structure
The valve consists of 3 main assemblies:
– Pilot control valve (1) with control spool and bushing,
return springs, double stroke solenoid and inductive
position transducer
– Main stage (2) with centering springs and position feed-
back
– Integrated control electronics (3)
Functional description
In the integrated electronics, the specified command val-
ue is compared with the actual position value of the main
stage control spool. In case of control deviations, the double
stroke solenoid is activated which adjusts the pilot control
spool due to the changed magnetic force. The flow released
through the control cross-sections causes the displacement
of the main control spool, the stroke/control cross-section of
which is controlled proportionally to the command value. If
the command value is 0 V, the electronic controls the control
spool of the main stage in the center position.
The pilot control valve is supplied with the pilot oil either in-
ternally through port P or externally through port X.
The re-
turn to the tank can be implemented internally via port T
or
externally via port Y.
If deactivated or in case of no release, the pilot control valve
is undefined in P-B/A-T (preferred) or P-A/B-T, the main
stage can be completely controlled.

The cleanliness classes specified for the components must be complied with in hydraulic systems.
Effective filtration prevents faults and at the same time increases the service life of the components.

Note
Pilot operated 4/3 directional control valves fulfill their func-
tion only in active closed control loops and do not have a
secured basic position when deactivated. Therefore, "addi-
tional isolator valves" are required in many applications and
must be taken into account for the On/Off series.
