Product Description
Rexroth Type 4WRKE Series Pilot-Operated Proportional Directional Valves
Product Overview: The 4WRKE Series is a high-performance, two-stage pilot-operated proportional directional valve with integrated electronics (OBE), engineered for precision flow and direction control in large-scale hydraulic systems. By utilizing a pilot stage to position the main spool, this series enables stepless proportional regulation of massive flow rates. The main spool position is monitored by an inductive position transducer, ensuring exceptional repeatability and dynamic stability.
This category highlights essential high-performance configurations: the 4WRKE25W8-350L (NG25, 350 L/min) and the 4WRKE10E100L (NG10, 100 L/min). These valves are the premier choice for large-scale injection molding machines, die-casting equipment, heavy forging presses, and industrial automated synchronization systems.
Key Technical Advantages:
Integrated Electronics (OBE): On-board control electronics are factory-calibrated for gain and zero-point, simplifying system integration while enhancing electromagnetic compatibility (EMC).
Two-Stage Pilot Architecture: Capable of controlling ultra-high flows—up to 3000 L/min—with minimal electrical input power while maintaining high dynamic response.
Precision Position Feedback: Features an inductive position sensor for the main spool, facilitating closed-loop control that significantly minimizes hysteresis and improves linearity.
High-Pressure Durability: Constructed with high-strength castings rated for pressures up to 315-350 Bar, ensuring reliability in demanding heavy-industrial environments.
