General specifications
The inlet section can be configured for either a fixed
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. Thanks to modularity concept, it's possible to
combine stacks of flexible sections across the entire EDG
family. The new On Board Electronics (OBE) module
ensures the maximum efficiency in all working conditions,
thanks to a control loop that allows an integration and
communication between sensors and hydraulic
components.

The EDG OBE pilot operated proportional sectional valves
with pressure compensation controls the oil flow to
actuators with a close loop.
These elements consist of a stackable housing (1) with a
control spool (2), an On Board Electronics (OBE) module
(4), one return spring (3). The OBE module (4) displaces
the control spool from its neutral-central position “0”
proportionally to the current received, with a control in
close loop. When the spool is shifted and the metering
notch is open, flow delivery starts and is controlled by a 2
way pressure compensator (5) (P > A; P > B).
Load pressure compensation
The pressure compensator (5) keeps the pressure
differential on the main spool (2). The flow to the
consumers remains constant, despite varying loads. Port
relief valves with anti-cavitation function on A and B (7)
protect the system against pressure peaks and cavitation.
LS relief valves (6), for each consumer port, can be
adjusted according to specific application requirements.
