Product Overview

The REXROTH 4WE 10 D5X/OFEG24N9K4/M (Material Number: R901278763) is a high-performance, direct-operated solenoid directional spool valve from the renowned Rexroth 4WE series. Engineered for precise control of start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a robust 4-way, 3-position (4/3) spool design. The “D” spool configuration provides a closed-center function, ensuring actuator ports are blocked in the neutral position for safe load holding. With a size 10 (NG10 / CETOP 5) interface, this valve is a critical component for demanding motion control applications, offering reliable switching and high flow capacity with minimal pressure drop.

Technical Specifications

Engineering Features & Advantages

• Precision Spool & Sleeve Design: The hardened, precision-ground spool and sleeve assembly ensures minimal internal leakage, precise metering characteristics, and long service life even under high cycle rates.
• High-Performance Solenoids: Equipped with wet-pin DC solenoids (24V), this valve provides fast, reliable switching with high force output. The integrated manual override allows for safe system diagnostics and emergency operation without power.
• Robust Construction: The valve housing is manufactured from high-strength cast iron, designed to withstand severe industrial environments, shock, and vibration.
• Model-Specific Fit: Supplied to the exact Rexroth code 4WE 10 D5X/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.

Understanding the Model Code: 4WE 10 D5X/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:

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.
