The Rexroth 4WRKE27W6-500L-3X/6EG24K31/A1M-909 is a high-response, direct operated proportional directional valve designed for demanding electro-hydraulic control applications. This valve features integrated on-board electronics (OBE) for precise control of flow direction and magnitude. Its robust construction ensures reliability and a long service life, making it ideal for closed-loop control systems in machinery requiring high dynamics and accuracy, such as machine tools, plastic processing machines, and test rigs. The valve is actuated by proportional solenoids with position feedback, providing excellent performance and repeatability.
