Product Overview
The Rexroth 4WE 10 J51/HG24N9K4/M (Material No. R901401552) 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 utilizes a precision-ground spool within a high-tensile cast iron housing. The “J” spool configuration provides a specific center condition (open center, P to T, A and B blocked) for versatile circuit logic. The “HG24” solenoid indicates a high-performance 24V DC wet-pin armature design with a manual override, ensuring reliable switching under high pressure. The “N9” designation refers to the standard electrical connection (DIN EN 175301-803, Form A, 3-pole). This valve is a critical component for precise motion control in demanding B2B applications, offering high flow capacity, low-pressure drop, and exceptional service life.

Engineering Features & Advantages
- Precision Spool & Sleeve Assembly: The hardened, ground, and honed spool and sleeve pair ensures minimal internal leakage, precise metering characteristics, and long switching life even under high cycle rates.
- High-Performance Wet-Pin Solenoid: The HG24 solenoid design provides high switching force, low power consumption, and excellent resistance to environmental factors (IP65 protection). The integrated manual override allows for safe system diagnostics and emergency operation.
- Optimized Flow Paths: The 4WE 10 series casting is engineered to minimize pressure drop across the valve, reducing heat generation and improving overall system energy efficiency.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Precision-manufactured to original REXROTH specifications for direct replacement, minimising downtime and eliminating fitment issues.
