Product Overview
The Rexroth 4WRKE16W6-200L-3X/6EG24K31/F1D3M (material number R901000254) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRKE series, size NG16 (nominal flow 200 L/min). It features integrated on-board electronics (OBE) with a ±10 V analog command interface and a spring-centered, fail-safe spool position. The valve uses a two-stage design in which a proportional pilot valve controls the main spool via hydraulic pilot pressure, enabling precise, continuously variable control of flow direction and magnitude in proportion to the electrical input signal. With a nominal flow of 200 L/min at a 10 bar valve pressure differential and a maximum operating pressure of 350 bar, this valve is engineered for demanding industrial motion-control loops requiring fast response, high flow capacity, and excellent repeatability.
