Product Overview
The Rexroth 4WRPH 10 C3 B100L-20/G24K0/M-750 (Material Number: 0811404902) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth WRPH series. Engineered for precise electro-hydraulic control, this valve features a 4-way, 3-position (4WRPH) spool configuration with a size 10 nominal flow path. The integrated proportional solenoid (G24K0) provides infinitely variable spool positioning proportional to the electrical input signal, enabling accurate directional and flow control of hydraulic actuators. The “B100L” designation indicates a specific spool type and nominal flow rating, while the “M-750” suffix denotes a customized or application-specific variant. This valve is a critical component in closed-loop and open-loop industrial systems requiring fast response, high repeatability, and smooth dynamic performance.
