Product Overview
The Rexroth 4WRPEH6C4B02L-31/M/24A1 (Material Number: R901382356) is a high-response, direct-operated proportional directional valve from the renowned Rexroth 4WRPEH series. Engineered for demanding closed-loop and open-loop control applications, this valve features a 4-way, 3-position spool configuration with a nominal flow rate of 2 L/min at a 10 bar pressure drop per land. The integrated 24V DC proportional solenoid with central electrical connection (M12 / DIN EN 175301-803 style) enables precise, infinitely variable control of flow direction and magnitude proportional to the input current. Its high-response design, characterized by minimal hysteresis, fast step response, and excellent repeatability, makes it an ideal choice for applications requiring dynamic motion control, position synchronization, and force regulation in industrial hydraulic systems. The valve is manufactured to Rexroth’s stringent quality standards, ensuring long service life, low leakage, and reliable operation even under harsh operating conditions.
