Rexroth 4WRPEH6 Series High-Dynamic Direct-Operated Servo Proportional Valves

Product Overview:

The Rexroth 4WRPEH6 Series is a direct-operated proportional directional valve with servo-grade performance, serving as a critical component in precision hydraulic closed-loop control. By integrating Digital On-Board Electronics (OBE) and an Inductive Displacement Transducer (LVDT), this series monitors spool position in real-time, ensuring extreme frequency response and micron-level adjustment accuracy. Whether for 24L fine control or 40L high-power output, the 4WRPEH6 maintains exceptional linearity under high pressures of up to 315 Bar, making it the premier choice for injection molding, test rigs, die-casting, and high-performance automation.

Featured models include the 4WRPEH6C4B24L-3X (latest 3X sequence), the high-flow 4WRPEH6C3B40L-20 (40L specification), and the 4WRPEH6CB24L-2X.

Key Technical Advantages:

• Servo-Grade Dynamics: Powerful solenoids directly drive the spool with integrated OBE, providing ultra-short step response times to accurately track high-frequency command signals.

• High-Precision Feedback: The built-in LVDT sensor provides real-time spool positioning, automatically compensating for flow-force disturbances and eliminating hysteresis.

• Plug-and-Play Integration: The OBE is integrated into the valve body and pre-calibrated for null and gain at the factory, simplifying wiring and commissioning.

• Versatile Interface Options: Offers M12 (A1), standard 6P+PE (K0), and current signal (F1) connectivity to meet various controller and PLC requirements.
