Product Overview
The Rexroth 4WE 10 D33/CG24N9K4 (Material Number: R900589933) is a high-performance solenoid-operated directional spool valve from the proven 4WE 10 series, designed for precise control of start, stop, and direction of hydraulic fluid flow in industrial hydraulic systems. Featuring a robust three-position, four-way (4/3) spool design with a “D” type center condition, this valve directs pressurized flow to the selected actuator port while returning displaced fluid to tank. The integrated wet-pin AC solenoid (24 V DC, coded “CG24”) provides fast, reliable shifting with high switching force, while the N9K4 designation indicates a standard high-power solenoid with manual override and a spring-centered, spring-return configuration. Engineered to ISO 4401 / DIN 24340 size 10 (NG10) mounting standards, this valve is a direct-fit, drop-in replacement for OEM Rexroth installations and is widely deployed in demanding industrial circuits requiring dependable directional control.

Understanding the Model Code: 4WE 10 D33/CG24N9K4
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 (4/3 Way) — NG10 (ISO 4401-05 / CETOP 5) |
| Spool D33 | Spool type D33 — metering and centre condition for this variant are listed in the specification table |
| CG24 | Solenoid — 24 V DC |
| K4 | Plug connector to DIN EN 175301-803 (ISO 4400) |
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 (see nameplate) against your valve nameplate, and confirm your control-circuit voltage and spool requirement.
