Product Overview
The Bosch Rexroth 4WRPEH 6 C4 B40L-30/M/24F1 (Material Number: R901382333) is a high-response, direct-operated proportional directional valve from the WRPEH series, designed for precise, high-dynamic control of flow direction and magnitude in industrial hydraulic systems. Featuring a 4-way, 3-position spool configuration with a closed-center design, this valve utilizes a high-performance proportional solenoid with integrated position feedback to deliver exceptional response sensitivity and repeatability. The “C4” spool type provides a specific flow characteristic optimized for fine metering, while the “B40L” designation indicates a nominal flow capacity of 40 L/min at a 30 bar pressure drop per land. The integrated digital or analog amplifier (designated by “M” for modular or integrated electronics) ensures precise current-to-stroke conversion, making this valve ideal for closed-loop position, velocity, and force control applications in demanding industrial environments.
