***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth 4WE10H73A5X/EG24N9K4/A12M (R901349998) is a high-performance directional spool valve designed for controlling the start, stop, and direction of fluid flow within a hydraulic system. This valve features a robust housing, one or two electronic solenoids, a control spool, and return springs that ensure reliable operation. The control spool remains in a central or initial position when de-energized and shifts to an end position upon solenoid actuation to enable the desired flow direction. The valve's manual override provides additional flexibility by allowing manual operation without electrical power. Equipped with throttle inserts in channels P, A, B, or T, this model can handle increased flow resistance when necessary due to operational conditions. It is available in several configurations with or without spring return and detent options for locking the control spool in position for energy-efficient usage. The non-spring return versions do not maintain a defined basic position when de-energized. Designed with porting patterns according to ISO standards, the 4WE10H73A5X/EG24N9K4/A12M offers high-power solenoids that can be rotated by 90 degrees for installation flexibility. Connection options include individual or central connections with compatibility for PWM connectors and fast switching amplifiers. Safety features include CE conformity for electrical voltages above certain thresholds and UL recognition for solenoid coils. This Bosch Rexroth directional valve is suitable for various hydraulic applications requiring precise control over fluid dynamics. It operates effectively even under pressure peaks in the tank line, though separate return lines or check valves are recommended to prevent unintended control spool movements in systems with detent valves.

4/3-, 4/2- or 3/2-way version Porting pattern according to ISO 4401-05-04-0-05 High-power solenoid, optionally rotatable by 90° Electrical connection as individual or central connection Use optionally with PWM connector (fast switching amplifier, energy reduction) Optional auxiliary operating device CE conformity according to the Low-Voltage Directive 2006/95/EC for electrical voltages >50 VAC or > 75VDC Solenoid coil with UR approval UL 429 Approval according to CSA C22.2 no. 139-10, optional

The directional valve type WE is a solenoid-actuated directional spool valve that can be used as electro-magnetic component. 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).

In the de-energized condition, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except for version "O").

If the wet-pin electronic solenoid (2) is energized, the control spool (3) moves out of its rest position into the required end position. In this way, the required direction of flow according to the selected symbol is released.

After the electronic solenoid (2) has been switched off, the control spool (3) is pushed back into its central position or into its initial position (except for valves with "OF" detent and valves without type "O" spring).

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.

For more functions, refer to the functional description.

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 unwanted movements of the control spool in the case of valves with detent! We therefore recommend that separate return lines be provided or a check valve installed in the tank line.

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. 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 3 1 /s. Due to possible overload of the board, valves with central connection must not be operated with twice the voltage. If the standard environmental conditions according to VDE 0580 cannot be provided, the valve must be especially protected!

Performance limits

(measured with HLP46, ϑOil = 40 ±5 °C)

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.

1)	Interference protection circuit integrated
2)	To be ensured by user circuitry

Notice!

When solenoid coils are switched off, voltage peaks result which may cause faults or damage in the connected control electronics. We therefore recommend limiting them to 2 x nominal voltage by means of an interference protection circuit. It must be noted that a diode switched in an antiparallel form extends the switching off time.

Special points with version "DAL" and "DL"

Version "DL" is only suitable for permanently installed cables. Lines must be routed in a strain-relieved manner! Minimum line cross-section 0.75 mm2 (AWG 18) With a maximum line cross-section of 1.5 mm2 (AWG 16) and if wire end ferrules are used, wire end ferrules without flange must be crimped to a maximum cross-section of 1.5 x 2 mm (trapezoidal crimp) using an appropriate tool (e. g. “PZ 6/5”, co. Weidmüller) to ensure that they fit into the printed circuit board terminals. Before crimping, the wires have to be stripped to 9-1 mm. For the corresponding line cross-section, 1) wire end ferrules without flange (according to DIN 46228-1) with a length of 8 mm are to be used. For the grounding connection, ring cable lugs according to DIN 46234-4-1 are to be used, tightening torque MA = 1.75 Nm ± 10 %

Notice:

The lines must be finely stranded.
