High-response valve, pilot operated, with electrical position feedback and integrated electronics | 4WRDE 5/22
RE 29093, edition: 2012-11, Bosch Rexroth AG
Function, section
Valves of type 4WRDE are 3-stage directional control valves.
They control the quantity and direction of a flow and are
mainly used in control loops for different tasks.
They consist of the following assemblies:
▶ The 2-stage pilot control valve consisting of the control
motor (1) and a hydraulic amplifier (5) designed as
nozzle flapper plate valve and the control spool socket
unit (6) as flow amplifier stage for actuating the 3rd
stage (7).
▶ The 3rd stage (7) for flow control.
▶ An inductive position transducer (8) the core (9) of
which is attached to the control spool (10) of the
3rdstage.
The position of the control spool (10) is measured by an
inductive position transducer (8). The signal linking of the
valve control loop, the supply of the position measurement
system and the control of the pilot control valve are carried
out via control electronics integrated in the valve.
The voltage difference created by the command/actual
value comparison is amplified in the control electronics and
supplied to the 1st stage of the valve as control deviation.
This signal deflects the flapper plate (2) between the two
control nozzles (3.1, 3.2). This creates a pressure differ-
ence between the two control chambers (11.1, 11.2). The
control spool (4) is moved and releases a corresponding
flow into the control chamber (12.1 or 12.2). The control
spool (10) with the core (9) of the inductive position trans-
ducer (8) attached to it is displaced until the actual value
corresponds to the command value. In the compensated
condition, the control spool (10) is held in the position
specified by the command value.
The control spool stroke is proportional to the command
value. For the control of the flow, a corresponding control
opening results, depending on the position of the control
spool (10) to the control edges (13), to which the flow is
proportional. The valve dynamics is optimized via the elec-
tric gain. The control electronics is integrated in the valve
(oscillator, demodulator).
Valve particularities
▶ The 3rd stage is basically set-up of modules of our
proportional valves.
▶ With V control spools, the control edges of control
spools and housings are ground in to each other.
▶ When the pilot control valve or the control electronics is
exchanged, they are to be re-adjusted. All adjustments
may be implemented by instructed experts only.
▶ The pilot control valve may only be maintained by
BoschRexroth employees. An exception to this is the
replacement of the filter and the sealing according to
the accessories list. It has to be ensured that during the
assembly, the sealing is properly seated and the plug
screw is tightened.
The tightening torque for the plug screw is 30 Nm.

1)
For a perfect system behavior, we recommend an external pilot oil
supply for pressures above 210 bar.
2)
q
Vnom
= rated flow (complete valve) in l/min with a V control spool.
3)
The cleanliness classes stated for the components need to be
maintained in hydraulic systems. Effective filtration prevents faults
and at the same time increases the life cycle of the components.
For the selection of the filters see www.boschrexroth.com/filter.

1)
With pending hydraulic pressure and deactivated enable, the
control spool of the main stage is moved into end position and the
cylinder axis leaves its position at maximum velocity. If a WG152
directional sandwich plate valve is used between pilot control
valve and main stage, the control chambers are unloaded from the
pilot control valve to the main control spool and the control spool
of the main stage is centered in central position or in a preferred
position by springs. Consequently, the cylinder axis leaves its
position at minimum velocity.
2)
Positive command value at D vis-à-vis E results in flow from P to A
at the main stage!
3)
Current input ±10 mA as option, input resistance 1 kΩ; in the
ordering code, extend the type by "– 280".
