Product Overview
The Rexroth 4WE 10 D50/EG205N9K4/V (material number R901336182) is a direct-operated, solenoid-actuated directional spool valve from the proven 4WE 10 series. Designed for controlling the start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a robust three-chamber housing, hardened and precision-ground spool, and wet-pin AC/DC solenoids for reliable, long-life switching performance. The “D50” spool type provides a closed-center, three-position, four-way function (P, A, B, T ports), making it ideal for precise actuator control in demanding machinery. With a nominal size of NG10 (CETOP 5 / ISO 4401-05), this valve delivers high flow capacity and low pressure drop, ensuring efficient system operation and energy savings.

Understanding the Model Code: 4WE 10 D50/EG205N9K4/V / R901336182
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 Directional Spool Valve (4-way, 3-position) — NG10 (CETOP 5, ISO 4401-05) |
| Spool D50 | Spool type D50 — metering and centre condition for this variant are listed in the specification table |
| K4 | Plug connector to DIN EN 175301-803 (ISO 4400) |
| R901336182 | 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 a standard coil version of the 4WE body (confirm the voltage block of your order on the nameplate). 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.

Frequently Asked Questions
Is the coil voltage important?
Yes — the coil is voltage-specific and must match your control circuit. Confirm the voltage block in the model code before ordering.
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 (R901336182) against your valve nameplate, and confirm your control-circuit voltage and spool requirement.
