Product Overview
The Rexroth 4WE 6 D73-62/EG24N9K4/A12 (Material No. R900546257) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 6 series. Designed for the control of start, stop, and direction of fluid flow in industrial hydraulic systems, this valve features a 3-position, 4-way (4/3) spool configuration with a “D” type center condition (closed center, all ports blocked in the neutral position). The valve is actuated by a high-performance wet-pin AC/DC solenoid on one side (single solenoid, spring return) operating at 24 V DC nominal voltage, with the designation “EG24” indicating the solenoid voltage and “N9” denoting the standard manual override. The “K4” suffix identifies the ISO 4401-03 (CETOP 3 / NG6) standard mounting interface, ensuring drop-in compatibility with a vast range of industrial manifolds and subplates. With a maximum operating pressure of 350 bar and a nominal flow capacity of up to 60 L/min, this valve delivers precise, repeatable directional control for demanding industrial duty cycles.
