Product Overview
The Rexroth 4WRTE 16 E1-125L-42/6EG24K31/A1M (R900954266) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRTE series, engineered for precise, dynamic control of flow direction and magnitude in demanding industrial hydraulic systems. Utilizing a two-stage design with a high-performance proportional solenoid pilot stage acting on a main spool, this valve delivers fast response times, excellent repeatability, and minimal hysteresis. The integrated electrical position feedback (E1 designation) ensures closed-loop spool position control, making it ideal for applications requiring accurate velocity and position regulation of hydraulic actuators. With a nominal size of NG16 and a rated flow capacity of 125 L/min at a 10 bar pressure drop per land, this valve serves as a critical control element in high-cycle industrial machinery where precision and reliability are paramount.
