Product Overview

The Rexroth 4WE 10 D52/HG24N9K4/M (Material Number R9010891200) 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 robust three-chamber housing, a hardened and precision-ground control spool, and a wet-pin AC/DC solenoid with a nominal voltage of 24 V DC. The “D52” spool type provides a closed-center, three-position, four-way function (P, A, B, T ports), while the “HG24N9K4/M” designation indicates a high-performance solenoid with a manual override, an ISO 4401-05 (NG10 / CETOP 5) mounting interface, and an N9 (NBR) seal kit. With a maximum operating pressure of 350 bar and a rated flow of up to 120 L/min, this valve is engineered for high-cycle, high-reliability applications in plastic injection molding, metallurgical presses, and mobile hydraulic systems.

Technical Specifications

Engineering Features & Advantages

• Precision Spool Metering: The hardened, ground, and lapped control spool ensures minimal internal leakage, precise flow metering, and long service life even under high-pressure, high-cycle operation.
• Wet-Pin Solenoid Technology: The 24 V DC wet-pin solenoid provides high switching force, low noise, and excellent resistance to contamination, ensuring reliable actuation in demanding industrial environments.
• Model-Specific Fit: Supplied to the exact Rexroth code 4WE 10 D52/HG24N9K4/M / R9010891200 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 maximum operating pressure of 350 bar and a rated flow of up to 120 L/min, this valve is engineered for high-cycle, high-reliability applications in plastic injection molding, metallurgical presses, and mobile hydraulic systems.

Understanding the Model Code: 4WE 10 D52/HG24N9K4/M / R9010891200

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 (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 (R9010891200) against your valve nameplate, and confirm your control-circuit voltage and spool requirement.
