Product Overview
The Rexroth 4WRPEH6C3B04L-31/M/24F1-885 (material number R901396969) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WRPEH series, designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. Featuring a 4-way, 3-position spool configuration with integrated position feedback, this valve converts an analog electrical command signal into a proportional hydraulic output, enabling smooth, infinitely variable actuation of cylinders and motors. Its nominal size 6 (NG6 / CETOP 3) interface and 24 V DC solenoid actuation make it a direct-fit solution for demanding closed-loop and open-loop motion control applications where accurate velocity, position, and force regulation are critical.
