Product Overview
The Rexroth 4WE 10 EA33/CG24N9K4 (Material Number: R900595532) is a high-performance solenoid-operated directional spool valve from the renowned Bosch Rexroth WE series. Designed as a 4-way, 3-position (4/3) directional control valve, it governs the start, stop, and direction of fluid flow in hydraulic systems by shifting a precision-ground spool within a hardened housing bore. Actuated by two wet-pin AC/DC solenoids with a central spring return, this valve provides reliable, fast switching for demanding industrial circuits. The “EA33” spool configuration delivers a specific flow path (P to A/B to T crossover) suited for differential cylinder control, while the “CG24N9K4” designation indicates a 24 V DC high-power solenoid with a concealed manual override and an ISO 4401 / CETOP 5 (NG10) mounting interface. As a direct-fit replacement for OEM Rexroth components, it ensures drop-in compatibility with existing manifolds and control blocks.
