Product Description

Rexroth 4WRKE25E350L-3X/6EG24K31/A1M-909 R901549111

The Rexroth 4WRKE25E350L-3X/6EG24K31/A1M-909 (Bosch Rexroth material number R901549111) is a high-performance, direct operated proportional directional control valve. It features electrical position feedback and integrated electronics (OBE) for precise hydraulic control. This NG25 valve is designed for subplate mounting according to ISO 4401 standards and offers a nominal flow rate of 350 L/min. The “E” spool configuration provides a 4-way, 3-position functionality with all ports blocked in the neutral, spring-centered position. The valve operates with a 24V DC supply, accepts a ±10V command signal, and includes an adjustable mechanical stroke limitation (“M” option) for application-specific tuning. Its robust design and reliable K31 electrical connector make it suitable for demanding industrial applications requiring accurate flow direction and magnitude control.
