Product Overview
The Rexroth 4WRPEH6C3B40L-31/M/24F1 (Material Number R901382350) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WRPEH series. Engineered with an integrated digital amplifier (OBE) and closed-loop position control of the main spool, this valve delivers precise, repeatable directional and flow control proportional to an electrical command signal. The “C3” spool design provides a critical-center overlap configuration suited for position and velocity control of actuators, while the “40L” flow rating corresponds to a nominal flow capacity of approximately 40 L/min at a 10 bar (Δp) pressure differential per land. With a standard 24 VDC solenoid actuation and the “F1” electrical interface, this valve is designed for seamless integration into modern industrial control architectures, offering fast response, minimal hysteresis, and excellent flow linearity for demanding motion control tasks.
