Product Overview
The Rexroth 4WRPEH6C4B12L-31/M/24F1 (Material Number: R901382331) is a high-response, direct-operated proportional directional valve from the renowned Rexroth 4WRPEH series. Engineered for precision electro-hydraulic control, this valve features a 4-way, 3-position spool configuration with a closed-center design (spool type “C4B12L”). It utilizes a high-performance proportional solenoid on one end and a spring return on the opposite end to achieve infinitely variable directional and flow control. The “High-Response” designation indicates a specially optimized solenoid and spool geometry that delivers exceptionally fast step responses and high dynamics, making it ideal for demanding closed-loop position, velocity, and force control applications in modern industrial hydraulic systems.
