Product Overview
The Rexroth 4WRKE 16 W8-200L-35/6EG24ETK31/A103M (Material Number R900711320) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Featuring a size 16 (NG16) main stage with a 200 L/min nominal flow rating at a 35 bar pressure differential across the valve, this two-stage valve combines a proportional pilot valve with a robust main spool stage. The integrated electrical position feedback (ET) and on-board control electronics (integrated amplifier) ensure exceptional repeatability, minimal hysteresis, and fast dynamic response. This valve is engineered for applications requiring smooth, infinitely variable directional control with high flow capacity and excellent pressure stability.
