Bosch Rexroth material number R900561281 is the 4WE6EB6X/EG24N9K4 Directional Spool Valve NG6, Spool Symbol EB, 24 VDC, 350 bar (size 6, Symbol EB, 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 R900561281; in Rexroth codes every character (spool, solenoid voltage, connector, manual override and seals) changes the part, so the type code 4WE6EB6X/EG24N9K4 on the nameplate should match exactly.
If the nameplate of the old part is unreadable, send us a photo of the part or the machine hydraulic diagram and we will identify the matching Rexroth material number.
Replacement checklist
- Seal material for your hydraulic fluid
- Maximum pressure and flow of the circuit
- Size (NG) and mounting pattern (ISO 4401 / cavity)
