Rexroth 4WRPEH Series Direct-Operated Proportional Servo Valves

Product Overview:

The Rexroth 4WRPEH Series is a direct-operated proportional directional valve with servo-grade performance. Featuring On-Board Electronics (OBE) and an integrated LVDT electrical feedback sensor, this series is engineered for high-precision closed-loop control of flow, direction, pressure, and position. By monitoring the spool position in real-time, the 4WRPEH series provides exceptional dynamic response and minimal hysteresis. Whether you require the latest 3X Design Series or the established 2X Series, it is the premier choice for precision presses, injection molding, machine tools, and simulation platforms.

Featured models on this page include the high-performance 4WRPEH6C4B24L-3X, 4WRPEH10C4B50L-3X, and the specialty spec L2X/G24Z31/F1.

Key Technical Advantages:

• Direct-Operated Dynamics: The proportional solenoid actuates the spool directly, ensuring rapid switching speeds ideal for demanding closed-loop systems.

• Integrated On-Board Electronics (OBE): Calibrated control electronics are built into the valve, simplifying wiring and offering robust Electromagnetic Compatibility (EMC).

• Inductive Position Feedback: The LVDT sensor provides closed-loop spool control, ensuring superior linearity and hysteresis of less than 0.1%.

• Industrial Durability: Precision-ground spool and sleeve assemblies maintain long-term null stability even under continuous 315 Bar high-pressure operation.
