Proportional directional cartridge valve | 2WFC; 2WFCE 4/28
RE 29403, edition: 2025-05, BoschRexrothAG
Set-up
The pilot-operated proportional directional cartridge
valve type2WFC(E) basically consists of:
▶ Cover(1)
▶ Main stage(2)
▶ Pilot control valve with proportional solenoid(3)
▶ Integrated electronics with position transducer and
analog interface(4) or external control electronics as
module amplier
Function, section
Function
The electronics (integrated or external) compare the
specified command value to the position actual value of
the control spool of the main stage(2). In case of control
deviations, the solenoid of the pilot control valve(3)
is activated. In this way, the control spool is adjusted.
Depending on the control deviation, the control chamber
of the main stage(2) is either pressurized with pilot oil
(the main stage closes) or unloaded (the main stage
opens). Stroke and orifice cross-section are controlled
proportionally to the command value until the control
deviation is remedied.
For proper function, the following has to be observed:
▶ Direction of owA →B (X connected to A)
▶ Direction of owB →A (X connected to B)
▶ PortY depressurized to the tank
▶ Pressure in port Y acts against the pressure in
ports A and B to open the main stage.
▶ Pressure in ports A and B simultaneously acts against
pilot pressure X
▶ Observe the leakage ow at the pilot control valve
Failure of supply voltage
If the minimum supply voltage fails or is fallen below, the
enable is disconnected (only interfaces "B1" and "G1")
and in case of acable break of the solenoid conductor,
the electronics will de-energize the solenoid of the pilot
control valve(3). The control spool of the main stage(2)
moves securely to its seat using the pressure available at
port X and the force of the main stage spring and blocks
the flow betweenA and B.
Notice:
Pilot oil must be present before the electronics are
switched on (also in case of error or emergency stop).

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 an 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 use with
HLP mineral oil. In order to reduce the cavitation effect,
it is recommended–if possible, specific to the
installation–to back 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.

using amanual torque wrench (tolerance±10%).
▶ The specified tightening torques were calculated with the
total friction coefficient µ=0.09…0.14; adapt to modified
surfaces.
▶ The tightening torque of the hexagon socket head cap screws
refers to the maximum operating pressure.

2 PortB can be of any size within the range between H6min
and H1max. The durability of the block depends on its
material and geometry.
PortB may be at any position around the central axis of
port A. However, it must be observed that the mounting
bores and the control bores are not damaged.
