Product Overview
The Rexroth 4WRZE16E150-74/6EG24EK31/A1M (Material Number: R900974758) is a high-performance, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. As part of the renowned Rexroth 4WRZE series, this valve features a size 16 (NG16) nominal bore and a rated flow capacity of 150 L/min at a 10 bar pressure drop per land. It utilizes a proportional solenoid on the pilot stage to actuate the main spool, enabling infinitely variable control of actuator speed and direction. The integrated position feedback and spring-centered design ensure exceptional repeatability, minimal hysteresis, and fast response times, making it the ideal choice for closed-loop control applications where accurate velocity and position regulation are critical.
