The Bosch Rexroth 4WE10D3X/CG24N9K4=CSA (R900958087) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This valve is characterized by its robust housing, electronic solenoids, control spool, and return springs which ensure reliable operation. The control spool can be actuated by wet-pin electronic solenoids that move it from a rest position to an active end position, allowing for precise direction of flow between ports.
This model features manual override capabilities that permit manual actuation of the valve without the need for solenoid power. It's essential to maintain an oil-filled pressure chamber in the solenoid to guarantee proper functionality. The throttle insert option allows for increased flow resistance in various channels (P, A, B, or T), enhancing performance under certain operating conditions.
The 4WE10D3X/CG24N9K4=CSA valve operates without spring return in its default state when de-energized; however, it can also be configured with a detent (OF version) to maintain the control spool in a selected position without continuous current application—offering energy-efficient operation.
It's important to note that pressure peaks in tank lines connected to multiple valves might cause unintentional control spool movements. Separate return lines or check valves are recommended solutions for this issue.
This specific model offers versatility with its 3 or 4-way versions and high-power solenoid design. It adheres to ISO porting patterns and features wet-pin AC solenoids with detachable coils that are rotatable by 90 degrees and replaceable without opening the sealed chamber. The electrical connections are customizable as either individual or central connections, with an optional auxiliary operating device available.
The valve supports a maximum operating pressure of up to 350 bar and can accommodate maximum flow rates of up to 120 l/min. It belongs to component series X and X2—indicating its modern engineering standards and compatibility with contemporary hydraulic systems.

The directional valve type WE is a solenoid-actuated directional spool valve. It controls the start, stop and direction of a flow.
The directional valve basically consists of housing (1), one or two electronic solenoids (2), control spool (3), and the return springs (4). When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except for version "O"). The control spool (3) is actuated by wet-pin electronic solenoids (2).
The force of electronic solenoid (2) acts via the plunger (5) on the control spool (3) and pushes the latter from its rest position to the required end position. This enables the necessary direction of flow from P to A and B to T or P to B and A to T.
When the electronic solenoid (2) is switched off, the return spring (4) pushes the control spool (3) back to its rest position.
A manual override (6) allows for the manual switching of the valve without solenoid energization.
To ensure proper functioning, make sure that the pressure chamber of the solenoid is filled with oil.
Type .WE 10 E…
Throttle insert "B.."
Using a throttle insert (7) in channels P, A, B or T, the flow resistance at the valve can be increased. Its use is required when, due to prevailing operating conditions, flows occur during the switching processes, which exceed the performance limit of the valve.
Without spring return “O” (only possible with symbols A, C and D)
This version is a directional valve with 2 spool positions and 2 electronic solenoids without detent.
The valve without spring return at the control spool (3) does not have a defined basic position in the de-energized condition.
Without spring return with detent “OF” (only possible with symbols A, C and D)
This version is a directional valve with 2 spool positions and 2 electronic solenoids with detent.
The detents are used to lock the control spool (3) in the relevant spool position. During operation,
continuous application of current to the electronic solenoid can thus be omitted which contributes to energy-efficient operation.
Notice!
Pressure peaks in the tank line to two or several valves can result in unintended
movements of the control spool if valves are equipped with a detent! We therefore recommend providing separate return lines or
installing a check valve in the tank line.

Notice!
Valve versions with electrical individual connection “K…” or central connection “DK…”, see Ordering code.
Notices!
The solenoid coils must not be painted. Actuation of the manual override is only possible up to a tank pressure of approx. 50 bar. Avoid damage to the bore of the manual override!(Special tool for actuation, separate order, material no. R900024943). When the manual override is blocked, actuation of the opposite solenoid must be ruled out!
The simultaneous actuation of 2 solenoids of one valve must be ruled out! Use cables that are approved for a working temperature above 105° C. When solenoid coils are switched off, voltage peaks result which may cause faults or damage in the connected control electronics. The user has to provide for a suitable circuit for limiting the voltage peaks. It must be noted that a diode switched in an antiparallel form extends the switching off time. Valves with individual connection and a supply voltage of 12 V or 24 V can be operated with twice the voltage to reduce the switching time. For this purpose, the voltage has to be reduced to the nominal valve voltage after 100 ms by means of pulse width modulation. The maximum admissible switching frequency is 5 1/s. Due to possible overload of the board, valves with central connection must not be operated with twice the voltage.
Notice!
AC solenoids can be used for 2 or 3 mains; e. g. solenoid type W110 for: 110V, 50Hz; 110 V, 60Hz; 120V, 60Hz
In the electrical connection, the protective earthing conductor (PE, grounded) is to be connected in accordance with the stipulations.
For applications outside these parameters, please consult us!

Notice!
The specified performance limits are valid for use with two directions of flow (e. g. from P to A and simultaneous return flow from B to T).
Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us!
The performance limit was determined when the solenoids were at operating temperature, at 10% undervoltage and without tank preloading.
