Compatibility and replacement
Order with the 10-character material number R901278778; in Rexroth codes every character (spool, solenoid voltage, connector, manual override and seals) changes the part, so the type code 4WE10U5X/EG24N9K4/M 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.
Before you replace it
- Maximum pressure and flow of the circuit
- Size (NG) and mounting pattern (ISO 4401 / cavity)
- Coil voltage and connector type
