Product Overview
The Rexroth 4WE 6 D62/EG24N9K4 S0407 (Material No. R900938379) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 6 series, size NG6 (CETOP 3 / ISO 4401-03). It controls the start, stop, and direction of hydraulic fluid flow by shifting a hardened steel spool within a precision-machined housing, using a wet-pin AC/DC solenoid on one end and a spring return on the opposite end. Configured in the “D” spool type (three-position, four-way, closed-center), the valve blocks all ports in the de-energized mid-position, making it ideal for holding actuator position and for use as a pilot valve in multi-stage directional control circuits. With a nominal flow capacity of up to 60 L/min and a maximum operating pressure of 350 bar, this valve is a standard building block in industrial hydraulic power and control systems.
