Product Description
Rexroth 4WRAE Direct-Operated Proportional Directional Valves
Product Overview:
The Bosch Rexroth 4WRAE series is an industrial-grade, direct-operated proportional directional control valve featuring Integrated On-Board Electronics (OBE). Designed for the stepless control of hydraulic oil flow direction and magnitude, these valves are ideal for systems where rapid response and compact installation are critical. Whether in Size 6 (NG6) or Size 10 (NG10), the 4WRAE series remains the top choice in 2026 for machine tool automation, light industrial presses, and test stands due to its “plug-and-play” design and high repeatability.
Featured models and part numbers: 4WRAE6E15-22/G24N9K31/F1V-660, 4WRAE6E15-2X/G24K31/A1V-280, and R901282085.
Key Technical Advantages:
Integrated OBE Digital Electronics: Proportional amplifiers are pre-mounted and calibrated on the valve, supporting standard A1 ($\pm 10\text{V}$) or F1 (4-20mA) command signals, significantly reducing control cabinet space.
Rapid Direct-Actuation: High-pressure proportional solenoids act directly on the spool, providing exceptionally fast response times and ensuring smooth transitions during dynamic cycles.
Series 2X/22 Optimization: Spanning the reliable 2X and enhanced 22 design sequences, these valves offer optimized spool force balancing for lower hysteresis and superior linearity.
Customized Version Support (-660/-280): Specific suffixes indicate tailored internal optimizations (e.g., specialized seals or orifices) for compatibility with unique hydraulic fluids or extreme conditions.
Rugged Industrial Protection: Rated at IP65, ensuring stable electrical connectivity and control output in environments prone to vibration, heat, and moisture.
