Product Description
Rexroth 4WRPEH 6 High-Response Proportional Valves
Product Overview: The Rexroth 4WRPEH 6 is a high-performance, direct-operated proportional directional control valve with integrated digital electronics (OBE). Featuring a spool-in-sleeve design, this series ensures exceptional control precision and dynamic response, making it the premier choice for closed-loop control systems in injection molding machines, die-casting, and high-end machine tools. Whether it is the 4WRPEH6C4B with specific flow characteristics or the optimized 4WRPEH6CB04L, these valves provide precise pressure and flow management via the A1M interface.
Featured part numbers: 0811404613, 4WRPEH6C4B40L-2X/G24K0/A1M, 4WRPEH6CB04L-2X, and 4WRPEH6CB24L-20.
Key Technical Advantages:
Integrated Digital Electronics (OBE): The built-in digital amplifier is factory-calibrated for superior linearity and minimal hysteresis, ensuring “plug-and-play” reliability.
Precision Spool/Sleeve Assembly: The wear-resistant spool-in-sleeve construction maintains long-term zero-lap stability and high-frequency response.
High Dynamic Performance: Optimized for servo-control loops requiring fast switching and high-precision positioning, with response times in the millisecond range.
Industry 4.0 Ready: The A1M interface supports standard analog control signals while offering advanced diagnostics and high electromagnetic compatibility (EMC).
