Product Overview
The Rexroth 4WRTE 16 E125L-46/6EG24EK31/A1M (Material Number R900979605) is a high-response, pilot-operated proportional directional valve designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. Manufactured by Bosch Rexroth, this valve belongs to the 4WRTE series, which features a two-stage design combining a pilot valve with a main spool stage. The valve utilizes proportional solenoid actuation to deliver infinitely variable spool positioning, enabling accurate directional control and velocity regulation of hydraulic actuators. With integrated position feedback and a high-response main stage, the 4WRTE 16 E125L-46/6EG24EK31/A1M is engineered for applications requiring fast dynamic response, minimal hysteresis, and excellent repeatability. The nominal size 16 (NG16) interface ensures compatibility with standard industrial mounting patterns, making it a direct replacement for OEM installations.
