Product Overview
The Rexroth 4WRPH6C3B40L-20/G24K0/M-750 (part number 0811404170) is a high-response, pilot-operated proportional directional valve from the Rexroth WRPH series, engineered for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. Utilizing a proportional solenoid with integrated position feedback, this valve delivers infinitely variable spool positioning proportional to the electrical command signal, enabling smooth acceleration and deceleration of actuators without pressure spikes. The NG6 (CETOP 3 / ISO 4401-03) size valve is designed for demanding closed-loop and open-loop applications where accurate velocity and position control are critical. Its robust construction and high-resolution metering characteristics make it a preferred choice for injection molding, press control, and precision motion systems requiring repeatable, dynamic performance.
