Product Overview
The Rexroth 4WRLE 16 X200M-30/G24K0/A1M-811 (material number 0811404256) is a pilot-operated, two-stage proportional directional valve from the Rexroth 4WRLE series, designed for high-response, closed-loop control of flow direction and magnitude in industrial hydraulic systems. The valve combines a pilot stage equipped with a proportional solenoid and a main stage with position feedback, enabling precise, continuously variable spool positioning proportional to the electrical command signal. With a nominal size of NG16 and a rated flow of 200 L/min at a 30 bar pressure differential, this valve is engineered for demanding motion-control applications requiring fast response, high resolution, and excellent repeatability. As a proportional directional valve, it regulates both the direction and rate of actuator movement, making it a core component in electrohydraulic control architectures.

Engineering Features & Advantages
- Precision Proportional Metering: The X200M spool profile delivers a finely graduated flow characteristic, enabling smooth, stepless control of actuator velocity with high resolution and minimal hysteresis.
- Integrated Position Feedback: The main spool position is continuously monitored and closed-loop controlled, ensuring accurate, repeatable spool positioning independent of flow forces and pressure fluctuations.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust construction and wear-resistant internal components for extended service life.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original Rexroth OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
