0821300932/力士樂壓力開關

For connection to the AC voltage mains, a DC solenoid must be
used, which is controlled via a rectifier (see table on the right).
Electrical control is realized via a mating connector with integrated
rectifier (separate order, see below).
Mating connectors, separate order, see below
Locating pin ISO 8752-3x8-St,
Material no. R900005694 (separate order)
The directional valve type Z4WE is a solenoid-operated directiona

lspool valve. It controls the start, stop and direction of
The directional valve basically consists of housing (1), one
or two solenoids (2), control spool (3), as well as two return
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 required
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
Due to the design principle, internal leakage is inherent to the
valves, which may increase over the service life.
