Product Overview
The Rexroth 4WE 10 E33/CW110N9K4 (Material Number R900597186) is a direct-operated, solenoid-actuated directional spool valve from the proven Rexroth 4WE 10 series, size NG10 (CETOP 5 / ISO 4401-05). It controls the start, stop, and direction of hydraulic fluid flow in industrial power circuits by shifting a hardened, precision-ground spool within a high-strength cast iron housing. The “E33” spool designation provides a closed-center, three-position configuration with blocked ports in the neutral position, while the “CW110” solenoid code denotes AC 110 V / 50 Hz (or 120 V / 60 Hz) wet-pin AC solenoids with integrated manual override. With a nominal flow capacity of approximately 80 L/min and a maximum operating pressure of 350 bar on ports P, A, and B, this valve is engineered for high-cycle, leak-tight directional control in demanding hydraulic systems.
