4/20 4WRA; 4WRAE | Proportional directional valve
BoschRexrothAG, RE29128, edition: 2023-11
The valve type4WRA(E) is adirect operated proportional
directional valve without electrical position feedback.
The solenoids are optionally controlled by external control
electronics or digital on-board electronics (OBED).
Set-up
The valve basically consists of:
▶ Housing(1) with connection surface
▶ Control spool(2) with compression springs(3 and 4)
▶ Solenoids(5 and 6) with central thread
▶ Digital on-board electronics (7), optional
Function
▶ With de-energized solenoids(5 and 6), central position
of the control spool(2) by compression springs
(3 and 4)
▶ Direct operation of the control spool(2) byenergization
of aproportional solenoid, e.g.control of solenoid
"b"(6)
– Displacement of the control spool(2) to the left
proportional to the electric input signal
– Connection fromP → A and B → T via
orice-typecross-sections with progressive ow
characteristic
▶ Switching off the solenoid(6)
– The compression spring(3) brings the control
spool(2) back into the central position
Notice:
▶ Due to the design principle, internal leakage is
inherent to the valves, which may increase over the
life cycle.
▶ The tank line must not be allowed to run empty.
With corresponding installation conditions,
apreload valve (preload pressure approx.2bar)
must be installed.
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 assembled and
disassembled 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(8).
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 datasheet30581
and operating instructions 30581-B.

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 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. In order to reduce the cavitation effect, it is
recommended–if possible specific to the
installation–backing up the return flow pressure in portsT to
approx.20% of the pressure differential at the component.
– Dependent on the hydraulic fluid used, the maximum ambient
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.

Safety instructions
IT security
The operation of installations, systems and machines
basically requires the implementation of aholistic IT
security concept which is state-of-the-art in terms of
technology.
Accordingly, Rexroth products and their properties
have to be considered as components of installations,
systems and machines for their holistic IT security
concept.
Unless otherwise documented, Rexroth products are
designed for operation in local, physically and logically
secured networks with access restrictions for authorized
persons, and they are not classified according to
IEC62443-4-2.
