Product Description
Rexroth 4WRPEH High-Response Proportional Directional Valves
Product Overview:
The Bosch Rexroth 4WRPEH series is a direct-operated proportional valve engineered for applications demanding extreme dynamic response and high-precision control. Positioned as the high-performance tier of Rexroth’s proportional family, it features Integrated On-Board Electronics (OBE) and utilizes full closed-loop spool position feedback. Available in NG6 and NG10 sizes, the 4WRPEH series delivers near-servo performance for 2026 precision injection molding, high-speed press control, and motion simulation platforms.
Featured models: 4WRPEH6C3B12L-20/G24K0/A1M and 4WRPEH6CB40L-30/G24K0/A1M.
Key Technical Advantages:
Extreme Dynamic Response: Driven by powerful proportional solenoids, these valves offer minimal step response times, making them capable of handling high-frequency oscillation signals.
Integrated OBE Electronics: The factory-mounted digital amplifier supports standard A1 ($\pm 10\text{V}$) command inputs, saving space while maximizing electromagnetic compatibility (EMC).
Full Closed-Loop Spool Feedback: Internal LVDT sensors monitor spool position in real-time, ensuring hysteresis $\le 0.1\%$ and maintaining linear output even under fluctuating system pressures.
Series 20 & 30 Iterations: * Series 20: The proven platform for reliability.
Series 30: Deeply optimized for fluid dynamics to further reduce internal pressure drop.
Versatile Spool Functions (C3B/CB): Features symmetrical or asymmetrical flow characteristics (e.g., 12L or 40L nominal flows) to precisely match actuator load requirements.
