Product Overview
The Rexroth 4WE 10 D50/OFEG110N9K4/M (Material Number R900010801) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series. Designed for controlling the start, stop, and direction of hydraulic fluid flow, this 4-way, 3-position (4/3) valve features a “D” type spool configuration with closed-center characteristics in the neutral position. The valve is actuated by two wet-pin AC solenoids (OFEG designation) rated for 110V AC operation, with a concealed manual override and a spring-centered return mechanism ensuring reliable spool positioning. With a nominal size of NG10 (Size 10) and a maximum operating pressure of 350 bar, this valve is engineered for high-cycle industrial duty, offering fast response, low leakage, and exceptional service life in demanding hydraulic circuits.
