Product Overview
The Rexroth 4WRTE 27 V76-500L-46/6EG24K31/A1M (R900977345) is a high-response, pilot-operated proportional directional valve with integrated position feedback, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a four-way, three-position spool configuration with a spring-centered failsafe position, this valve delivers exceptional dynamic response and repeatability. The model designation “500L” indicates a nominal flow capacity of 500 L/min at a 10 bar pressure differential across the valve, making it ideally suited for high-flow, high-precision applications. The integrated OBE (On-Board Electronics) with ±10V or 4–20 mA command interface ensures seamless integration with modern PLC and motion control architectures. As part of the Rexroth 4WRTE series, this valve is engineered for continuous duty in closed-loop position, velocity, and force control circuits.
