General specifi cations
▶ In an assembly EDG block, the inlet section can be
confi gured for either a fi xed displacement pump or
load-sense variable displacement pump. When
simultaneous machine functions are actuated, the pre-
compensators will automatically adjust to the highest
load pressure via a shuttle arrangement, making the
system circuit independent of variations in loads and
pump pressures.

4/3 and 4/2 On-Off directional valve elements | EDG-DO...
Functional description

Functional description
The EDG direct acting On-Off solenoid sectional valves with
pressure compensation control the oil fl ow to actuators.
These elements consist of a stackable housing (1) with a
control spool (2), two solenoids (4), two return springs (3).
Each solenoid (4), energized, displaces the control spool
from its neutral-central position. When the spool is shifted,
flow delivery starts and is controlled by a 2 way pressure
compensator(7) (P > A; P > B).
When the solenoid is de-energized, the return spring
pushes the spool back in its neutral-central position.
Each coil (4) is fastened to the solenoid tube by the ring
nut (5). A push-pin manual override is included to actuate
the valve without electrical power as needed.
Load pressure compensation
The pressure compensator (7) keeps the pressure
diff erential on the main spool (2). The fl ow to the
consumers remains constant, despite varying loads.
The highest load pressure on the pump is signaled via the
LS line and the integrated shuttle valve (6).
Port relief valves with anti-cavitation function on A and B
(9) protect the system against pressure peaks and
cavitation. LS relief valves (8), for each consumer port, can
be adjusted according to specifi c application requirements.
