Function, section
The directional valve type Z4WE is a solenoid-operated direc-
tional spool valve. It controls the start, stop and direction of
a flow.
The directional valve basically consists of housing (1), one
or two solenoids (2), control spool (3), as well as two return
springs (4).
In the de-energized condition, control spool (3) is held in the
central position or in the initial position by the return springs (4).
The control spool (3) is actuated by wet-pin solenoids (2).
To ensure proper functioning, care must be taken that
the pressure chamber of the solenoid is filled with oil.
The force of solenoid (2) acts via plunger (5) on control
spool (3) and pushes the latter from its rest position to the re-
quired end position. This opens up the required flow direction
A② to A① and B② to B①.
After solenoid (2) was de-energized, return spring (4) pushes
control spool (3) again back to its rest position.
An optional manual override (6) allows control spool (3) to be
moved without energization of the solenoid.
Notice!
Due to the design principle, internal leakage is inherent to the
valves, which may increase over the service life.
Admissible shock and vibration loads see data sheet 08012.

Important information on hydraulic fluids!
– For more information and data on the use of other hydrau-
lic fluids refer to data sheet 90220 or contact us!
– There may be limitations regarding the technical valve
data (temperature, pressure range, service life, mainte-
nance intervals, etc.)!
– The flash point of the process and operating medium used
must be 15 K higher than the maximum solenoid sur-
face temperature.
– Flame-resistant – water-containing: Maximum pressure
differential per control edge 175 bar; otherwise, increased
cavitation erosion! Tank pre-loading < 1 bar or > 20 % of
the pressure differential. The pressure peaks should not
exceed the maximum operating pressures!
– Environmentally compatible: When using environmen-
tally compatible hydraulic fluids that are simultaneously
zinc-solving, zinc may accumulate in the medium (700 mg
zinc per pole tube).
1)
The cleanliness classes specified for the components must
be adhered to in hydraulic systems. Effective filtration pre-
vents faults and at the same time increases the service life
of the components.

3)
The switching times have been determined at a hydraulic
fluid temperature of 40 °C and 46 cSt. Deviating hydraulic
fluid temperatures can result in different switching times!
Switching times change depending on operating time and
application conditions.
4)
Due to the temperatures occurring at the surfaces of the
solenoid coils, the standards ISO 13732-1 and EN 982
need to be adhered to!
The specified surface temperature in AC voltage solenoids
is valid for the faultless operation. In case of failure (e. g.
blocking of the control spool), the surface temperature
may rise to above 180 °C. Considering the flash point (see
page 8), the system must therefore be checked for pos-
sible risks.
As fuse protection, circuit breakers (see table on the
right) must be used unless the creation of an ignitable
atmosphere can be excluded in a different way. Thus, the
surface temperature can - in case of failure - be limited to
maximally 220 °C. The tripping current must lie within a
time interval of 0.6 s with 8 to 10 times the nominal power
consumption. (Tripping characteristics "K").
The necessary non-tripping current of the fuse must not fall
below the value I
1
(see table page 16). The maximum
tripping current of the fuse must not exceed the value I
2
(see table page 16).
The temperature dependence of the tripping behavior of
the circuit breakers has to be considered according to the
manufacturer's specifications.
Notices!
– Actuation of the manual override is only possible up to a
tank pressure of ca. 50 bar. Avoid damage to the bore for
the manual override! (Special tool for the operation, sepa-
rate order, Material no. R900024943). When the manual
override is blocked, the operation of the solenoid must be
ruled out!
– The simultaneous operation of the solenoids must be
ruled out!
Notice!
AC solenoids can be used for 2 or 3 mains,
e.g. solenoid type W110 for:
110 V, 50 Hz; 110 V, 60 Hz; 120 V, 60 Hz
