Product Overview
The Rexroth 4WRPEH6C3B12L-31/M/24A1 (Material Number R901382312) is a high-response, direct-operated proportional directional valve from the Rexroth 4WRPEH series. Engineered for precise electro-hydraulic control of flow direction and magnitude, this valve utilizes a robust proportional solenoid with integrated position feedback to deliver exceptional dynamic response and repeatability. The “C3” spool design provides a specific flow characteristic suited for critical motion control applications, while the “L” designation indicates a spring-centered, fail-safe neutral position. This valve serves as a critical control element in demanding industrial systems, translating low-power electrical command signals into high-power hydraulic actuation with minimal hysteresis and excellent linearity.
