Product Overview
The Rexroth 4WRAE6E30-30/VN9/24A1 (material number R890000346) is a direct-operated, proportional directional valve from the Bosch Rexroth 4WRAE series, size 6 (NG6 / CETOP 3). It controls the direction and magnitude of flow in proportion to the electrical input signal applied to its proportional solenoids, making it the core interface between electronic control systems and hydraulic actuators. With a spring-centred, three-position spool design and integrated position feedback, the valve delivers smooth, stepless directional control with minimal hysteresis, enabling precise velocity and force regulation in demanding industrial circuits. The “E30” spool variant provides a defined mid-position overlap characteristic suited to controlled deceleration and load holding, while the 24 V DC solenoid configuration is compatible with standard industrial amplifier cards such as the Rexroth VT-VSPA or VT-2000 series.
