Rexroth 4WRPEH & 4WREE High-Response Proportional Valves

Product Overview:

The Bosch Rexroth 4WRPEH and 4WREE series represent the pinnacle of industrial proportional hydraulic technology. The 4WRPEH is a high-response valve engineered for applications demanding rapid reaction times and servo-level precision, while the 4WREE provides exceptional stability through its closed-loop position feedback. Both series feature Integrated On-Board Electronics (OBE) and real-time spool position monitoring. In 2026, they remain the premier choice for high-speed injection molding, motion simulation platforms, and precision forging equipment.

Featured models: 4WRPEH6C3B40L-3X/M/24A1, 4WRPEH10C3B100L-3X/M/24A1, 4WREE10E75-2X/G24K31/A1V, and 4WRPEH6C4B24L-3X/M/24A1.

Key Technical Advantages:

• Integrated OBE Digital Electronics: Proportional amplifiers are factory-mounted and pre-calibrated, supporting standard A1 ($\pm 10\text{V}$) command inputs. This integrated design maximizes cabinet space while ensuring superior EMC performance.

• Direct-Actuated High Response (4WRPEH): Powered by heavy-duty proportional solenoids, these valves offer minimal step response times, making them capable of handling high-frequency oscillation signals.

• LVDT Closed-Loop Feedback: Internal sensors monitor spool position in real-time, reducing hysteresis to $\le 0.1\%$ and ensuring flow output remains independent of load fluctuations.

• Series 3X Platform Optimization: The 4WRPEH 3X design optimizes fluid dynamics to support higher flow rates (up to 100 L/min) while significantly reducing internal pressure drop.

• Versatile Spool Logic (C3B/C4B/E): Covers a broad range of nominal flow rates (12L to 100L) to perfectly match symmetric and asymmetric load requirements.
