Product Overview
The Rexroth 4WE 10 D50/OFEG24N9K4/M (Material Number R901278763) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series (Size 10 / NG10, CETOP 5). Designed for controlling the start, stop, and direction of hydraulic fluid flow in industrial power units, this valve features a robust three-land spool design housed in a high-strength cast iron body. The “D50” spool configuration provides a closed-center (all ports blocked in neutral) function, ensuring load holding and precise actuator positioning. Equipped with a 24V DC wet-pin solenoid and a concealed manual override, this valve delivers reliable, high-cycle switching performance in demanding hydraulic circuits.

Engineering Features & Advantages
- Precision Performance: The solenoid operated directional spool valve (4-way, 3-position) delivers precise, repeatable performance with low hysteresis and stable control across the full working range.
- Model-Specific Fit: Supplied to the exact Rexroth code 4WE 10 D50/OFEG24N9K4/M / R901278763 with standard N9 / K4 interfaces, so it fits existing 4WE installations without modification.
- Circuit-Matched Spool: The spool variant supplied matches this listing’s code; for a different centre condition or metering requirement, compare the related listings or send us your original code.
Typical Industrial Applications
Designed for controlling the start, stop, and direction of hydraulic fluid flow in industrial power units, this valve features a robust three-land spool design housed in a high-strength cast iron body.
Understanding the Model Code: 4WE 10 D50/OFEG24N9K4/M / R901278763
Each block of the Rexroth model code describes one attribute of the valve. Use this breakdown together with the specification table above to confirm the exact configuration you need:
| Code Block | Meaning |
|---|---|
| 4WE 10 | Solenoid Operated Directional Spool Valve (4-Way, 3-Position) — NG10 (ISO 4401-05 / CETOP 5) |
| Spool D50 | Spool type D50 — metering and centre condition for this variant are listed in the specification table |
| FEG24 | Solenoid — 24 V DC |
| K4 | Plug connector to DIN EN 175301-803 (ISO 4400) |
| R901278763 | Rexroth material (order) number |
Always verify the complete code and material number against the nameplate on your existing valve before ordering — body size, spool type and coil voltage must all match.
Choosing the Right Variant
This listing is the 24 V DC version of the 4WE body. Coil voltage and spool type are the two attributes that decide compatibility in most retrofits — the same body size is available with different coils (EG24 / EW110 / W230 …) and different spools. Related listings:

Frequently Asked Questions
Is the coil voltage important?
Yes. This unit uses a 24 V DC solenoid; the coil is voltage-specific and must match your control circuit.
Can I change the coil voltage after installation?
The valve body is shared across the 4WE series, but the solenoid coil itself is voltage-specific; for a different supply voltage you need the matching coil (or the complete valve in that voltage variant). Confirm the coil part number with our team.
What do N9 and K4 mean?
N9 = concealed manual override for emergency actuation; K4 = plug connector to DIN EN 175301-803 (ISO 4400) — the standard electrical interface on most machines using 4WE valves.
What should I check before ordering?
Match the complete model code and material number (R901278763) against your valve nameplate, and confirm your control-circuit voltage and spool requirement.
