Product Overview
The Rexroth 4WRKE 16 W6-220L-3X/6EG24EK31/A1M-909 (Material Number R901551915) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRKE series, size NG16. It is engineered to control both the direction and the magnitude of flow in proportion to an electrical input signal, making it a core control element in demanding industrial hydraulic systems. The valve combines a pilot stage with a main stage spool, actuated by a proportional solenoid with integrated position feedback, delivering precise, repeatable metering of flow for smooth acceleration, deceleration, and load positioning. With a rated flow of approximately 220 L/min at a 10 bar (Δp) valve pressure differential and a 3X series design, this valve is suited for closed-loop and open-loop applications requiring fast response, high resolution, and excellent dynamic performance.
