Product Description
Rexroth 4WRKE Pilot-Operated Proportional Directional Valves
Product Overview:
The Bosch Rexroth 4WRKE series stands as a premier solution for high-flow control in industrial hydraulics. As a two-stage pilot-operated proportional directional valve featuring Integrated On-Board Electronics (OBE), it is specifically designed for precise regulation of hydraulic oil flow and direction. Covering nominal sizes from NG10 to NG32, the 4WRKE series is highly sought after in 2026 for high-end die-casting machines, heavy-duty brick presses, and steel production lines, ensuring exceptional stability under heavy load conditions via closed-loop spool position feedback.
Featured model and part number: 4WRKE16E1-125L-3X/6EG24ETK31/A1D3M and R900246794.
Key Technical Advantages:
Two-Stage High Dynamics: The pilot-operated architecture ensures rapid response times even under extreme system pressures and large volumetric flows.
Integrated OBE Digital Electronics: The factory-mounted amplifier supports standard A1 ($\pm 10\text{V}$) command inputs, significantly reducing wiring complexity and effectively shielding against electromagnetic interference (EMI).
Closed-Loop Spool Feedback: Internal high-precision LVDT sensors monitor and correct the main spool position in real-time, reducing hysteresis to $\le 0.1\%$ and ensuring consistent flow output.
Optimized 3X Design Platform: Utilizing the latest 3X sequence, the internal channels are optimized to reduce pressure drop and enhance overall system energy efficiency.
Enhanced ETK31 Configuration: Includes advanced diagnostics and superior electrical connection protection, designed to withstand extreme vibration and high-temperature challenges.
