Product Overview
The Rexroth 4WRZ16W6-150-74/6EG24N9K4/D3M (material number R900707161) is a pilot-operated, two-stage proportional directional valve from the renowned Rexroth 4WRZ series. Designed for continuous, high-dynamic control of flow direction and magnitude in industrial hydraulic systems, this valve utilizes a proportional solenoid pilot stage to actuate the main spool. The 4WRZ series is specifically engineered to provide precise, infinitely variable control of actuator speed and position, making it a critical component in demanding closed-loop and open-loop applications. With a nominal size of NG16 and a rated flow capacity of 150 L/min, this valve delivers robust performance and exceptional reliability in the most rigorous industrial environments.
