Bosch Rexroth material number R901278783 is the 4WE10D5X/EG24N9K4/V Directional Spool Valve NG10, Spool Symbol D, 24 VDC, 350 bar (size 10, Symbol D, with solenoid actuation, 24 VDC).
A WE directional valve is the standard way to switch an actuator in a hydraulic power unit: the wet-pin solenoid shifts the spool against springs, and the spool symbol decides the flow paths and the centre position.

Compatibility and replacement
Order with the 10-character material number R901278783; in Rexroth codes every character (spool, solenoid voltage, connector, manual override and seals) changes the part, so the type code 4WE10D5X/EG24N9K4/V on the nameplate should match exactly.
The values in the table come from the official Bosch Rexroth product data. If your old part shows a different series index (for example 5X instead of 6X), send us a photo and we will confirm the current equivalent.
Replacement checklist
- Spool or function symbol
- Size (NG) and mounting pattern (ISO 4401 / cavity)
