Product Overview
The Rexroth 4WRZE16W6-150-74/6EG24N9K31/A1D3M (Material Number: R900244520) is a high-performance, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 16 (NG16) nominal bore, this valve utilizes a proportional solenoid on the pilot stage to infinitely vary the position of the main spool, enabling smooth, stepless control of actuator velocity and direction. The “W6” spool configuration provides a specific flow characteristic optimized for critical positioning tasks. Engineered for robust operation, this valve is a direct-fit replacement for original OEM components, ensuring seamless integration into existing manifolds and control blocks.
