Product Overview
The Rexroth 4WRZ 16 E 150-74/6EG24N9EK4/M (Material Number R900977992) is a pilot-operated, two-stage proportional directional valve designed for precise, continuous control of flow direction and magnitude in industrial hydraulic systems. As part of the Rexroth 4WRZ series, this valve utilizes a proportional solenoid pilot stage acting on a main spool to deliver infinitely variable directional and flow control proportional to the electrical input signal. With a nominal size of NG16 and a rated flow capacity of 150 L/min at a 10 bar pressure differential, this valve is engineered for high-response, high-flow applications requiring accurate velocity and position control of hydraulic actuators. The integrated on-board electronics (OBE) with the “E” designation provide closed-loop position feedback of the main spool, ensuring exceptional repeatability and dynamic performance. This valve is a direct-fit, OEM-compatible component suitable for demanding industrial environments where precision and reliability are paramount.
