Product Overview
The Rexroth 4WRAE6W07-23/G24N9K31/A1V (Material Number: R900932003) is a high-performance, direct-operated proportional directional valve designed for precise control of flow direction and magnitude in industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve features a 4-way, 3-position spool configuration with integrated position feedback and a proportional solenoid actuator. The “W07” spool type provides a specific flow characteristic optimized for fine metering and smooth acceleration/deceleration of actuators. The “23” designates a nominal flow rate of 23 L/min at a pressure drop of 10 bar per metering edge. The “G24” indicates a 24 V DC proportional solenoid, while “N9” specifies the electrical connector type. The “K31” refers to the integrated control electronics (OBE) with a command signal of 0 to ±10 V or 4 to 20 mA. The “A1V” suffix denotes a specific spool variant and seal material (NBR). This valve is a critical component in closed-loop control systems, enabling precise velocity, position, and force control in injection molding machines, presses, and other demanding industrial applications.
