Product Overview
The Rexroth 4WRKE16E1-125L-3X/6EG24ETK31/F1D3M (Material No. R901051897) is a high-response, pilot-operated proportional directional valve from the renowned Rexroth 4WRKE series. Engineered for precise control of flow direction and magnitude in demanding industrial hydraulic systems, this valve utilizes a two-stage design: a pilot stage with a proportional solenoid and a main stage with a position-controlled spool. The “E1” designation indicates a positive spool overlap, ensuring a closed-center condition for load holding and safe system behavior. The “125L” code specifies a nominal flow rate of 125 L/min at a 10 bar pressure drop per land. This valve is a critical component for achieving smooth, accurate, and dynamic motion control in high-performance machinery.
