Product Overview
The Rexroth 4WREE6W1-32-30/V/24A1 (R901496447) is a high-performance, direct-operated proportional directional valve from the renowned Rexroth 4WREE series. Engineered for precise control of flow direction and magnitude, this valve operates on a proportional solenoid principle, where the spool position is infinitely variable and directly proportional to the electrical input signal. This allows for smooth, stepless control of actuator speed and direction in demanding industrial hydraulic systems. The “W1” spool design provides a specific flow metering characteristic, making it ideal for applications requiring fine control and excellent repeatability. With a nominal size of 6 and a flow rate of up to 32 L/min, it is a compact yet powerful solution for modern, energy-efficient hydraulic circuits.
