Product Overview
The Rexroth 4WRPEH6C3B12L-31/M/24F1 (Material Number R901382348) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WRPEH series. Featuring a size 6 (NG6 / CETOP 3) subplate interface, this valve uses a precision-machined spool within a hardened sleeve to proportionally control both flow direction and magnitude in response to an analog electrical command signal. The integrated position feedback and high-response solenoid actuation deliver fast, repeatable spool positioning, making it a critical control element for electro-hydraulic motion control loops in demanding industrial systems. The “C3” spool type provides a closed-center configuration with defined overlap characteristics, while the “12L” designation indicates a nominal flow rating of approximately 12 L/min at a 10 bar (Δp) pressure drop per land. The “24F1” suffix denotes a 24 VDC high-response proportional solenoid with integrated position transducer, enabling closed-loop spool position control via a Rexroth proportional amplifier card.
