Rexroth 4WRSE High-Response Proportional Directional Valves

Product Overview:

The Rexroth 4WRSE series (including 4WRSE6 and 4WRSE10) represents high-performance, direct-operated proportional directional valves designed for closed-loop control systems requiring extreme dynamic response. Featuring Integrated Electronics (OBE) and internal Position Feedback (LVDT), this series ensures high-precision spool positioning with servo-level performance. Characterized by minimal hysteresis and superior repeatability, the 4WRSE series is widely utilized in injection molding, test stands, die-casting machinery, and precision machine tool automation.

Featured models: 4WRSE10V1-50-3X/G24K0/F1V, 4WRSE6V04-31/G24K0/A1V, and 4WRSE10V1-80-3X/G24.

Key Technical Advantages:

• Servo-Class Dynamics: Exceptional frequency response bandwidth enables flawless tracking of fast-changing command signals for instantaneous control.

• On-Board Electronics (OBE): Integrated digital amplifier simplifies wiring and provides industry-leading EMI resistance.

• High-Precision Displacement Feedback: The built-in LVDT sensor reduces hysteresis to below $0.1\%$, ensuring smooth and stable control logic.

• Versatile Signal Interfaces: Compatible with standard industrial modes such as A1V ($\pm10\text{V}$ voltage signal) or F1V ($4-20\text{mA}$ current signal).

• Series 3X Design: The latest design generation optimizes internal flow paths, reducing pressure drops and increasing power density.
