Product Description
LIC Hydraulic offers the Rexroth 4WRDE Series, a flagship line of 3-stage pilot-operated proportional directional valves. Designed for sophisticated closed-loop control systems, the 4WRDE combines high flow capacity with extreme dynamic response. Featuring dual LVDT feedback for both the pilot and main stages, and Integrated Onboard Electronics (OBE), models like the 4WRDE25V350L and 4WRDE27W500L provide the industry’s highest level of precision and reliability for large-scale industrial hydraulics.
Technical Specifications (Quick Reference)
Series: 4WRDE (Sizes 25, 27, 32).
Mounting Pattern: ISO 4401 (NG25 to NG32).
Control Type: Pilot-operated 3-stage with LVDT feedback.
Max Flow: Up to $3000\text{ L/min}$ (size 32).
Pressure Rating: Main stage up to $350\text{ bar}$ ($5000\text{ PSI}$).
Key Technical Advantages
Dual-Loop Control: Continuous monitoring of both pilot and main spool positions virtually eliminates hysteresis and ensures ultra-precise flow adjustment.
High-Speed Dynamics: Specifically tuned for applications requiring fast acceleration and deceleration ramps with high bandwidth.
Pre-Calibrated OBE: The integrated amplifier is factory-set for linearity, reducing commissioning time and ensuring consistent performance across replacements.
Fail-Safe Options: Built-in monitoring for signal loss and voltage drops ensures the valve moves to a safe position during electrical faults.
Application Areas
Heavy Forging Presses: Precision slide speed and position control.
Metal Casting & Rolling: Controlling roll gaps in steel mills and injection speed in die-casting machines.
Advanced Simulation: High-dynamic motion control for industrial test benches.
Expert Maintenance Tips
Filtration is Critical: Maintain oil cleanliness at or above ISO 4406 17/15/12. Contamination in the pilot stage is the primary cause of spool sticking or erratic control.
Pilot Oil Source: Verify whether your system uses an internal or external pilot supply (X-port). Incorrect pilot configuration will prevent the main spool from moving.
Signal Shielding: Use high-quality shielded cables for the control signal to prevent electromagnetic noise from affecting the sensitive LVDT feedback loops.
