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

Product Overview: The Rexroth 4WRSE Series is a direct-operated proportional directional valve offering servo-grade performance. Featuring Integrated On-Board Electronics (OBE) and an Inductive Displacement Transducer (LVDT), this series provides real-time closed-loop control of the spool position, resulting in exceptional frequency response, minimal hysteresis, and superior repeatability. Designed to provide a streamlined alternative to complex electro-hydraulic servo valves, the 4WRSE is widely utilized in plastics machinery, precision presses, machine tools, and hydraulic actuators requiring high-frequency dynamic response.

Featured on this page are the compact precision 4WRSE6V04-3X and the high-flow performance model 4WRSE10E80-32.

Key Technical Advantages:

• Servo-Grade Dynamics: Driven by powerful direct-acting solenoids with integrated OBE, these valves deliver ultra-short step response times for real-time tracking of high-frequency command signals.

• Integrated Position Feedback (LVDT): The LVDT sensor monitors spool displacement in real-time, effectively compensating for flow-force load disturbances to ensure a linear relationship between input and output.

• Plug-and-Play OBE: On-board electronics are factory-calibrated for gain and zero-point. Users provide standard analog signals, eliminating external amplifiers and simplifying cabinet design.

• High Precision Control: Optimized with a zero-lap spool design, providing exceptional sensitivity and flow resolution near the neutral position.
