Rexroth 4WRPEH10 Series High-Dynamic Direct-Operated Servo Proportional Valves

Product Overview:

The Rexroth 4WRPEH10 Series is a direct-operated proportional directional valve with servo-grade characteristics, specifically engineered for industrial closed-loop controls requiring high flow rates and extreme dynamic response. Featuring a standard Size 10 (NG10) interface, this series utilizes powerful proportional solenoids and an integrated LVDT (Inductive Displacement Transducer) for sub-micron monitoring of spool position. With its On-Board Electronics (OBE), it receives analog command signals directly, providing superior linearity and minimal hysteresis—making it a core component for injection molding, die-casting, and high-performance press controls.

Featured models include the R901494085 (4WRPEH10C3B100L) and the 4WRPEH10C3B50L-2X.

Key Technical Advantages:

• Direct-Operated Servo Performance: The solenoid drives the spool directly without a pilot stage, ensuring ultra-fast response and high stability across the entire pressure range.

• High-Precision Feedback System: The built-in LVDT sensor ensures real-time closed-loop control of spool position, automatically compensating for flow-force disturbances to guarantee positioning accuracy.

• Plug-and-Play (OBE): Integrated control electronics simplify the electrical system architecture and enhance EMI resistance through factory-calibrated precision.

• High Reliability: Designed for continuous production environments, supporting operating pressures up to 315 Bar with excellent null stability and long-term durability.
