Product Overview
The Rexroth 4WRPEH6C4B24L-31/M/24A1 (Material Number R901382346) is a high-response, direct-operated proportional directional valve from the Bosch Rexroth 4WRPEH series, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a 4-way, 3-position spool configuration with a closed-center (C) design, this valve utilizes a high-force proportional solenoid with integrated position feedback to deliver fast, repeatable response and excellent flow linearity. The size 6 (NG6 / CETOP 3) valve is rated for continuous operating pressures up to 315 bar and is engineered for applications requiring high dynamic performance, low hysteresis, and accurate velocity or position control of hydraulic actuators.
