Product Overview
The Rexroth 4WREF 10 W1-50-23/G24K31/A1V (Material Number R900933077) is a high-performance proportional directional valve from the Rexroth 4WREF series, designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. Utilizing a direct-operated proportional solenoid with position feedback, this valve features a robust spool-in-sleeve design that enables infinitely variable directional control proportional to the electrical input signal. The integrated position feedback (W1 designation) ensures high repeatability and precise spool positioning, making it ideal for applications requiring accurate velocity and position control of hydraulic actuators. With a nominal size of NG10 (Size 10) and a maximum operating pressure of 315 bar, this valve serves as a critical control element in demanding industrial circuits where smooth, responsive, and energy-efficient motion control is essential.
