Product Overview
The Rexroth 4WRPEH6C4B04L-31/M/24A1 (material number R901382317) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WRPEH series. Featuring a four-way, three-position (4/3) spool design with a nominal size of 6 (NG6 / CETOP 3 interface), this valve uses a high-force proportional solenoid with integrated position feedback to deliver exceptionally fast, precise, and repeatable control of flow direction and magnitude. The “C4B04L” spool code denotes a closed-center, overlapped spool with a rated flow of approximately 4 L/min at a 10 bar (Δp) pressure drop per metering edge, making it ideal for high-accuracy velocity, position, and force control loops in demanding industrial hydraulic systems. With a 24 VDC (24A1) solenoid and a spring-centered, fail-safe neutral position, the valve is engineered for continuous duty in closed-loop electrohydraulic control architectures.
