4/18 3DRE(M)(E) | Proportional pressure reducing valve, pilot operated
Bosch Rexroth AG, RE 29286, edition: 2014-02
The valve types 3DRE(M) and 3DRE(M)E are electrically
pilot operated 3-way pressure reducing valves with pres-
sure limitation of the actuator.
They are used for reducing a system pressure.
Technical set-up
The valve consists of two main assemblies:
▶ Pilot control valve (1) with proportional solenoid (2)
optionally with maximum pressure limitation (15)
▶ Main valve (3) with main spool (4)
Function
General function:
▶ Command value-dependent setting of the pressure to be
reduced in port A via the pilot control valve (1).
▶ With depressurized port P, the springs (5) and (6) hold
the main spool (4) in its central position. In this way,
astart-up jump at the actuator is prevented.
▶ Pilot oil flows from bore (7) via the flow controller (8),
via the control chamber (11) to the throttle gap (9), via
line (10) to port Y. This connection is to be led into the
tank at zero pressure.
Pressure reduction:
▶ Build-up of the pilot pressure in the control cham-
ber(11) as function of the command value.
▶ Pressure build-up in the spring chamber (13) via noz-
zle(12) and movement of the main spool (4) to the
right, hydraulic fluid flows from P to A.
Function, section
▶ The actuator pressure in port A is available in the spring
chamber (14).
▶ Increase in the pressure in port A to the set pressure of
the pilot control valve (1) leads to the movement of the
main spool (4) to the left. The pressure in port A is
almost equal to the pressure set at the pilot control
valve (1).
Pressure limitation:
▶ If the pressure in port A exceeds the set pressure of the
pilot control valve (1), the main spool (4) is moved
further to the left.
▶ This opens the connection from A to T and limits the
pressure pending in port A to the set command value.
Type 3DREM
For hydraulic protection against an inadmissibly high elec-
tric control current at the proportional solenoid, which
imperatively results in increased pressures in port A, you
can optionally install a spring-loaded pressure relief valve
as maximum pressure limitation (15). This maximum pres-
sure limitation is pre-set, referred to the relevant pressure
rating (table page 6).

Type 3DREE and 3DREME – with integrated electronics (OBE)
With regard to function and set-up, these valves correspond to
types 3DRE and 3DREM. At the pilot control valve, there is
moreover a housing (19) with the control electronics.
Supply and command value voltage are applied at the
connector (20).
At the factory, the command value pressure characteristic
curve is adjusted with little manufacturing tolerance.

Integrated electronics (OBE) with type 3DRE(M)E
Function
The electronics are supplied with voltage via ports A and B.
The command value is applied to the differential amplifier
ports D and E.
Via the characteristic curve generator, the command value
solenoid current characteristic curve is adjusted to the
valve so that non-linearities in the hydraulics are compensa-
ted for and a linear command value pressure characteristic
curve is created.
The current controller controls the solenoid current inde-
pendently of the solenoid coil resistance.
The power stage of the electronics for controlling the pro-
portional solenoid is a chopper amplifier with a cycle fre-
quency of approx. 180 Hz to 400 Hz. The output signal is
pulse-width modulated (PWM).
For checking the solenoid current, a voltage can be measu-
red at the connector between pin F(+) and pin C(–) that is
proportional to the solenoid current. 1 mV corresponds to
1 mA solenoid current.

Type 3DRE(M)
1)
With valve type 3DRE(M), the manufacturing tolerance at
the external amplifier (type and data sheet see page 16)
can be changed using the command value attenuator poten-
tiometer "Gw". The digital amplifier is set using the param-
eter "Limit".
In this context, the control current according to the techni-
cal data must not be exceeded.
In order to be able to adjust several valves to the same
characteristic curve, do not set the pressure higher than
the maximum set pressure of the pressure rating with
command value 100 %.
