Product Description
Rexroth Type 4WREE6 Series Direct-Operated Proportional Valves
Product Overview: The 4WREE6 Series is a high-performance, direct-operated proportional directional valve designed for the precise control of both fluid direction and flow rate. This series features OBE (On-Board Electronics), allowing for the direct conversion of analog command signals into accurate spool displacement. Fully compliant with ISO 4401-03 (NG6) mounting standards, it is a cornerstone component for closed-loop control in industrial automation.
This category highlights essential configurations: the 16 L/min capacity 4WREE6E16 and the precision 4WREE6E04 (4 L/min). Powered by G24 (DC24V) and utilizing K31 connectors, these valves offer high dynamic response and minimal hysteresis, making them the premier choice for plastic processing machinery, machine tool controls, flight simulators, and general industrial HPUs.
Key Technical Advantages:
On-Board Electronics (OBE): The integrated amplifier is factory-calibrated for zero point and gain, simplifying wiring and enhancing electromagnetic compatibility (EMC).
Position Feedback Control: Utilizes an inductive position transducer to monitor spool travel, ensuring exceptional repeatability and dynamic stability.
Versatile Sealing Options: Available with A1V (NBR) or F1V (Viton) seals, compatible with mineral oils or various synthetic hydraulic fluids.
Compact High Performance: Rated for pressures up to 315 Bar within a standard NG6 frame, providing superior power density.
