Product Overview
The Rexroth 4WRPEH6C3B40L-31/M/24A1 (Material Number R901382315) is a high-response, direct-operated proportional directional valve from the Rexroth 4WRPEH series. Designed with a 4-way, 3-position spool configuration, this valve delivers precise, continuously variable control of flow direction and magnitude in proportion to an electrical input signal. Featuring an integrated digital amplifier (OBE) with 24 VDC supply and ±10 V analog command interface, the 4WRPEH6C3B40L-31/M/24A1 provides exceptional dynamic response, minimal hysteresis, and excellent repeatability. It serves as a critical control element in closed-loop and open-loop hydraulic systems requiring fast, accurate positioning of actuators, cylinders, and motors.
