Product Overview
The Rexroth 4WE 10 C30/HG24N9K4/V (Material No. R901391703) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series. Designed for controlling the start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a 3-position, 4-way spool configuration with a closed-center (C) design. The “HG24N9K4” designation indicates a high-performance wet-pin AC/DC solenoid with a nominal voltage of 24V DC, an N9 manual override, and an ISO 4401-compliant mounting interface. With a nominal flow capacity of up to 120 L/min and a maximum operating pressure of 350 bar, this valve delivers precise, reliable directional control for demanding industrial applications.

Engineering Features & Advantages
- Precision Performance: The integrated dual Wet-Pin Solenoid, 24V DC (HG24) ensures precise, repeatable control with low hysteresis and stable performance across the full working range.
- Rated Capability: Rated for pressure ratings of ports P, A, B: 350 bar; Port T: 160 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 C30/HG24N9K4/V 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
With a nominal flow capacity of up to 120 L/min and a maximum operating pressure of 350 bar, this valve delivers precise, reliable directional control for demanding industrial applications.
Understanding the Model Code: 4WE 10 C30/HG24N9K4/V
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 (ISO 4401-05 / CETOP 5) |
| Spool C30 | Spool type C30 — metering and centre condition for this variant are listed in the specification table |
| HG24 | Solenoid — 24 V DC (high-power coil) |
| 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 (high-power coil) 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 (high-power coil) 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.
