Proportional pressure reducing valve | 3DRE(E)(A); Z3DRE(E)(A) 5/32
RE29283, edition: 2023-01, BoschRexrothAG
Type3DRE…
TypeZ3DRE…
Valves of type3DREand Z3DREare electrically
pilot-operated 3-way pressure reducing valves with
pressure limitation of the actuator. They are used for
reducing asystem pressure.
The valve basically consists of apilot control valve(1),
proportional solenoid(2), main valve(3) with main
control spool(4).
General
In rest position, i.e., without pressure in channel P,
the spring holds the main control spool in the initial
position. This opens the connection fromA (P①) to T
and blocks the connection from P toA (P①).
With pressure connection from port P, pilot oil flows
via the flow controller(5) and nozzle, and the throttle
gap to the pilot control valve(1) and afterwards flows
to channel T.
The command value-dependent setting of the pressure to
be reduced in channelA(P①) is effected using the
proportional solenoid.
Type 3DRE
The pilot pressure builds up in the control chamber(6)
as a function of the command value. This moves the
main control spool(4) to the right, hydraulic fluid flows
fromP to A.
The actuator pressure in channelA is applied to the
spring chamber(9) via the channel(7) and the
nozzle(8). If the pressure in portA increases to the
set pressure of the pilot control valve, this leads to
movement of the main control spool(4) to the left.
The pressure in portA is almost identical to the set
pressure at the pilot control valve.
If, however, the pressure in portA exceeds the set
pressure of the pilot control valve, the main
controlspool(4) is moved further to the left so that
the connection fromA to T is opened. In this way,
the pressure in portA is limited to the set
commandvalue.
Type Z3DRE
In principle, the function of this valve version
corresponds to the function of type3DRE.
The pressure reduction is, however, effected in channel P①.

BoschRexrothAG, RE29283, edition: 2023-01
Type (Z)3DREE – with integrated digital electronics
(OBED)
With regard to function and set-up, this version
corresponds to type (Z)3DRE.
The digital on-board electronics (OBED) (10) are mounted
on the proportional solenoid. It may be equipped with
different electric interfaces:
▶ Analog interface (XH1)
– Interface "A1" (command value 0…10V)
– Interface "F1" (command value 4…20mA)
▶ Digital interface (XH5)
– IO-Link "L1"
Type (Z)3DREA – with integrated digital electronics
(OBED) and pressure control
With regard to function and set-up, this version
corresponds to type (Z)3DREE.
This valve version also has apressure transducer(11).
The latter is either directly attached on the carrier(12)
or may be externally integrated in the system via the
interface (X2N).
The pressure transducer (11) records the pressure
in channelP, which is then regulated independently of
the flow via the integrated electronics(10).
The pressure in channel A (P①) is output via the
connector (XH1, XH5) as analog or digital actual value
(0…10V or 4…20mA or in the unit [bar]).
If the command value is zero, the integrated electronics
only apply the minimum control current to the
proportional solenoid and the minimum set pressure
is applied.
Function: Type (Z)3DREE and (Z)3DREA
Bluetooth® function
The digital on-board electronics (OBED) provide the
user with adigital diagnosis interface via aBluetooth®
dongle (Bluetooth® Low Energy). It may also be ordered
as an accessory and retrofitted. The Bluetooth® dongle
may only be attached when the valve is de-energized.
By means of the "easy2connect app", the valve status
can be displayed and configurations at the valve can be
carried out via the Bluetooth® dongle(13).
Notice:
▶ The "easy2connect app" can be downloaded in
the App Store (iOS) or Google Play Store (Android).
▶ Further information on the Bluetooth® dongle
VT-ZBT-1-1X (R901505294) as well as set-up and
installation of the app is available in

Important information on hydraulic uids:
▶ For further information and data on the use of other
hydraulic fluids, please refer to the datasheets above or
contact us.
▶ There may be limitations regarding the technical valve data
(temperature, pressure range, life cycle, maintenance intervals,
etc.).
▶ The ignition temperature of the hydraulic fluid used must be
50K higher than the maximum surface temperature.
▶ Bio-degradable and flame-resistant–containing water:
If components with galvanic zinc coating (e.g.,version"J3" or "J5")
or parts containing zinc are used, small amounts of dissolved
zinc may get into the hydraulic system and cause accelerated
aging of the hydraulic fluid. Zinc soap may form as achemical
reaction product, which may clog filters, nozzles and
solenoid valves–particularly in connection with local heat input.
▶ Flame-resistant–containing water:
– Due to the increased cavitation tendency with the use of
HFChydraulic fluids, the life cycle of the component
may be reduced by up to 30% as compared to the use
with mineral oil HLP.
– Dependent on the hydraulic fluid used, the maximum
environment and hydraulic fluid temperature must not
exceed 50°C. In order to reduce the heat input into the
component, the command value profile is to be adjusted
for proportional and high-response valves.

or P24,
max.50mA (short-circuit-proof).
Observe the voltage range of the
pressure sensor.
2 I
Meas
Current input 4…20mA, connected
to GND via 100Ω load resistance +2V
diode path. Measuring input
congurable via Bluetooth® or IO-Link.
3 GND Reference potential; do not connect
in the case of two-wire system
(current input).
4 U

Connected to the housing via the
thread.
Notice:
▶ In the condition as supplied, the actual value input PIN4
0.1…10V of the pressure sensor interface is configured.
▶ Connection cable up to 10 m cable length with screening
connected to both line ends.
▶ The pressure sensor signal interface is always configured to
voltage signal.
▶ The pressure sensor signal can be independently changed
via IO-Link or via the Bluetooth® interface by means of
"easy2connect app".

In order to be able to adjust several valves to the same
characteristic curve, the manufacturing tolerance can -
with version"(Z)3DRE" - be changed at the external amplifier
(seepage27) using the command value attenuator "G,"
In this connection, do not set the pressure higher
than the maximum set pressure of the pressure rating with
command value 100%.
