Product Overview
The Rexroth 4WRPEH10C3B100L-30/M/24A1 (Material Number R901493886) is a high-response, direct-operated proportional directional valve from the Rexroth 4WRPEH series, engineered for precise, continuous control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a four-way, three-position spool design 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. The size 10 (NG10 / CETOP 5) valve is actuated by a single proportional solenoid with a spring-centered return, providing fail-safe centering in the event of power loss. Its high-response spool positioning and closed-loop feedback architecture make it a preferred choice for closed-loop motion control, velocity regulation, and force control in plastic injection molding, metallurgical, and machine tool applications.
