Rexroth 4WRAE6W30-23 Direct-Operated Proportional Valves

Product Overview:

The Bosch Rexroth 4WRAE6W30-23 is a high-performance, direct-operated proportional directional control valve engineered for the stepless, precise regulation of both hydraulic flow direction and magnitude. Featuring Integrated On-Board Electronics (OBE), this valve eliminates the need for external amplifiers. In 2026, the 4WRAE6 remains the premier choice for high-precision machine tools, automated production lines, and industrial test stands, providing a compact footprint and exceptional control repeatability.

Featured models: 4WRAE6W30-23/G24K31/A1V and 4WRAE6W30-23/G24N9K31/F1V.

Key Technical Advantages:

• Integrated OBE Digital Electronics: The proportional amplifier is factory-mounted and pre-calibrated on the valve. This integrated design saves cabinet space and significantly boosts electromagnetic interference (EMI) resistance in harsh environments.

• Versatile Signal Interfaces:

  • A1V Version: Supports standard $\pm 10\text{V}$ voltage commands, compatible with most conventional analog control systems.

  • F1V Version: Supports $4-20\text{mA}$ current commands, offering superior signal stability over long distances.

• Direct-Actuated High Response: High-pressure proportional solenoids act directly on the spool, providing rapid response times and the ability to execute minute flow adjustments.

• Optimized Series 23 Platform: The latest series 23 design enhances spool force balancing, resulting in lower hysteresis and superior linearity across the control range.

• W30 Spool Characteristics: Features a symmetrical W30 flow profile with a nominal flow rate of 30 L/min, ensuring consistent performance for both directions of actuator movement.
