Rexroth 4WRSE Series High-Performance Proportional Valves with OBE

Product Overview:

The Rexroth 4WRSE series stands as a pinnacle in proportional valve technology, specifically engineered for applications demanding extreme dynamic performance and superior control precision. As a direct-operated proportional directional valve, it integrates OBE (On-Board Electronics) and electrical position feedback. By monitoring the spool position in real-time, the 4WRSE provides servo-like response times and ultra-low hysteresis ($< 0.1\%$). Available in W6 and V spool configurations, this series achieves precise flow control up to 80 L/min at NG10 (Size 10), making it ideal for plastics machinery, test stands, and complex closed-loop systems.

Featured models: R900917263, 4WRSE10W6-80-3X/G24K0/A1V, and 4WRSE10V80-3X/G24K0/A1V.

Key Technical Advantages:

• Servo-Class Dynamics: Driven by powerful proportional solenoids, this series offers rapid response frequencies suitable for high-frequency switching and precision motion profiles.

• Integrated OBE Digital Drive: The amplifier is mounted directly on the valve, simplifying field wiring and eliminating EMI, supporting $\pm 10\text{V}$ analog control.

• Closed-Loop Electrical Feedback: Internal LVDT sensors monitor spool displacement in real-time, ensuring excellent linearity and stability even under fluctuating system pressures.

• Robust Series 3X Design: Optimized internal galleries reduce flow resistance and improve the overall energy efficiency of the hydraulic system.

• Exceptional Reliability: Built to meet 2026 industrial automation standards with high ingress protection and long-term operational stability.
