Product Overview
The Rexroth 4WRPE10CB80M-20/G24K0/A1M-846 (part number 0811404818) is a high-response, direct-operated proportional directional valve from the renowned Rexroth WRPE series. Engineered for demanding closed-loop and open-loop industrial control applications, this valve features a 4-way, 3-position spool design with integrated position feedback for exceptional dynamic response and precise flow metering. The “CB80” spool configuration provides a specific flow characteristic optimized for smooth, progressive control of actuator speed and direction. With a nominal flow capacity of 80 L/min at a 10 bar pressure drop per land, this valve is ideally suited for applications requiring fast, accurate directional control of hydraulic cylinders and motors. The integrated OBE (On-Board Electronics) with a G24K0/A1M electrical interface ensures simplified wiring, superior signal conditioning, and reliable operation with standard 24 V DC industrial control systems. As a direct replacement for OEM Rexroth components, this valve delivers the exacting performance and durability expected in high-cycle industrial machinery.
