Product Overview
The Rexroth 4WRKE 10W5-100L-37/6EG24ETK31/F1D3M (Material No. R900766091) is a high-response, pilot-operated proportional directional valve from the Rexroth 4WRKE series, designed for precise control of flow direction and magnitude in demanding industrial hydraulic systems. The valve operates on a two-stage principle: a proportional pilot valve with a wet-pin DC solenoid controls the pilot pressure, which in turn actuates the main spool of the second stage. The main stage features position feedback via an integrated inductive displacement transducer, enabling closed-loop spool position control for exceptional repeatability and dynamic response. With a nominal size of NG10 (size 10) and a rated flow of 100 L/min at a 10 bar pressure drop per land, this valve is engineered for continuous duty in high-cycle industrial applications where accurate velocity, force, and position control of hydraulic actuators is essential.
