Product Overview
The Rexroth 4WE 10 D50/EG24N9K4/M (material number R901278760) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 10 series. Designed for subplate mounting in accordance with ISO 4401 / DIN 24340 (NG10 / CETOP 5), this valve controls the start, stop, and direction of hydraulic fluid flow within industrial power units and machine circuits. The “D50” designation indicates a three-position, spring-centered spool with a closed-center (all ports blocked in neutral) configuration, while the “EG24” solenoid rating denotes 24 V DC wet-pin AC/DC solenoids with integrated manual override. The “N9” identifies the electrical connector standard (DIN EN 175301-803, 3-pole), and the “K4” suffix specifies the high-performance solenoid system with a nominal voltage tolerance suitable for demanding industrial duty cycles. This valve is a direct-fit replacement for OEM Rexroth installations and is engineered for precise, repeatable directional control in high-cycle hydraulic systems.

Engineering Features & Advantages
- Precision Performance: The integrated two wet-pin solenoids, 24 V DC, with manual override ensures precise, repeatable control with low hysteresis and stable performance across the full working range.
- Rated Capability: Rated for pressure ratings up to 350 bar and flow rates up to 120 L/min, supporting stable operation across the full working range.
- Model-Specific Fit: Supplied to the exact Rexroth code 4WE 10 D50/EG24N9K4/M / R901278760 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
This valve is a direct-fit replacement for OEM Rexroth installations and is engineered for precise, repeatable directional control in high-cycle hydraulic systems.
Understanding the Model Code: 4WE 10 D50/EG24N9K4/M / R901278760
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 | Directional Control Valve (Solenoid-Operated Directional Spool Valve) — NG10 (ISO 4401-05 / CETOP 5) |
| Spool D50 | Spool type D50 — metering and centre condition for this variant are listed in the specification table |
| EG24 | Solenoid — 24 V DC |
| K4 | Plug connector to DIN EN 175301-803 (ISO 4400) |
| R901278760 | 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 (R901278760) against your valve nameplate, and confirm your control-circuit voltage and spool requirement.
