Product Description
Rexroth High-Dynamic Proportional Servo Valves (4WRLE & 4WRPEH)
Product Overview: The Rexroth 4WRLE and 4WRPEH series define the pinnacle of proportional valve technology. These valves are engineered for hydraulic systems demanding ultra-high dynamic response and precision closed-loop control. The 4WRPEH6 is a direct-operated proportional servo valve, while the 4WRLE16 provides pilot-operated high-flow control. Both series feature OBE (Integrated Electronics) for real-time spool position feedback, effectively eliminating hysteresis and ensuring linear output at high switching frequencies. They are widely utilized in test stands, precision injection molding, and die-casting machinery.
Featured models include: 4WRLE16V200L-3X/G24K0/A1M (R901125221) and 4WRPEH6C3B12L-2X=G24K0/A1M=00 (R901349897).
Key Technical Advantages:
Servo-Grade Dynamics: Exceptional spool acceleration and high bandwidth frequency response, meeting the most demanding dynamic closed-loop control requirements.
Integrated OBE Electronics: On-board digital/analog controllers allow “Plug-and-Play” operation with integrated diagnostics and status monitoring.
Precision Feedback System: Utilizes inductive position transducers for closed-loop control of the main spool, ensuring superior repeatability and linearity errors below 0.1%.
High-Performance Build: Optimized for high-pressure, high-flow environments with precision-ground spool/sleeve assemblies for extended service life and contamination resistance.
