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

Product Overview: The Rexroth 4WRPEH Series is a direct-operated proportional directional valve with servo-grade performance. Its primary advantage lies in the integration of Closed-Loop Position Control (LVDT Feedback) and Integrated Digital On-Board Electronics (OBE). Compared to standard proportional valves, the 4WRPEH series offers significantly higher frequency response and minimal hysteresis, enabling ultra-fast and precise regulation of flow and direction. It is the premier choice for high-performance closed-loop systems such as blow molding machines, sheet metal processing, and precision hydraulic actuators.

Featured models on this page include the 4WRPEH6 (R901382347) and the high-flow 4WRPEH10 series.

Key Technical Advantages:

• Servo-Grade Dynamic Response: Driven by powerful solenoids with integrated OBE, the valve delivers ultra-short step response times, allowing for real-time tracking of high-frequency signals.

• High-Precision Position Feedback: The built-in LVDT sensor monitors spool position in real-time, ensuring the spool stays exactly where the command dictates, regardless of operating conditions.

• Integrated OBE Design: On-board electronics are pre-calibrated at the factory. Users provide standard analog signals, eliminating the need for external controllers and reducing system complexity.

• Zero-Lap Spool Design: Optimized for response speed and control linearity near the neutral position, ensuring precise transitions and high resolution.
