Product Overview
The Rexroth 4WRKE16W8-200L-3X/6EG24EK31/A1D3M (Material Number R900247386) is a high-response, pilot-operated proportional directional valve with integrated position feedback, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. As part of the Rexroth 4WRKE series, this valve features a size 16 (NG16) main stage with a nominal flow capacity of 200 L/min at a 10 bar pressure differential across the valve, and belongs to component series 3X. The valve operates on a two-stage working principle: a proportional pilot valve with a wet-pin DC solenoid controls the pilot pressure, which in turn actuates the main spool of the second stage. An integrated electrical position feedback system continuously monitors main spool position, enabling closed-loop control of spool stroke and therefore precise, load-independent metering of flow. The “W8” spool type provides a specific progressive flow characteristic optimized for smooth acceleration and deceleration of actuators. With a 24 VDC solenoid (EG24) and a spring-centered, fail-safe neutral position, this valve is engineered for applications requiring high dynamic response, excellent repeatability, and reliable directional control of hydraulic actuators in continuous industrial duty.
