General specifi cations
Valve elements with solenoid operated directional spool.
Control spools directly operated by solenoids with
removable coils.
In the de-energized condition, the control spool is held
in the central position by return springs.
Wet pin tubes for DC coils, with push rod for mechanical
override; zinc plated surface.
Coils can be rotated 180° around the tube; they can be
energized by AC current throught special connection
with rectifi er (RAC).
Manual override (push-button, screw type) available as
option.
Different plug-in connectors available: see ordering
details.

The sandwich plate design directional valve elements D8_5
are compact direct operated solenoid valves which control
the start, the stop and the direction of the oil fl ow. These
elements basically consist of a stackable housing (1) with a
control spool (2), one or two solenoids (5), and one or two
return springs (4). The spring chambre are connected to
the tank port. When the coil is energized, the spool (2)
travels and oil is pushed to tank from one of the spring
chambers: if the cross section of the orifi ces changes, the
switching time changes as well. Three orifi ce sizes are
available: smaller orifi ce results in longer switching time,
even though the actual time is dependent upon pressure,
fl ow and viscosity.When energized, the force of the
solenoid (5) pushes the control spool (2) from its neutral-
central position to the required position, and the required
fl ow from P to A (with B to T), or P to B (with A to T) is
achieved. Once the solenoid is de-energized, the return
spring (4) pushes the spool thrust washer (3) back against
the housing and the spool returns in its neutral-central
position. Each coil is fastened to the solenoid tube by a ring
nut (6). A pin (7) allows to push the spool (2) in emergency
conditions, when the solenoid cannot be energized, like in
case of voltage shortage. The secondary cartridge valves
are designed for quick response and stable pressure
control (8); they also incorporate a reverse fl ow check for
anti-cavitation.
