Bosch Rexroth R900597186 Valve

The Bosch Rexroth R900597186 is a 4-way, 2-position electric directional valve (model 4WE10E3X/CW110N9K4) designed to direct hydraulic flow in industrial and mobile equipment. This Rexroth valve uses electric actuation to switch flow between the A and B actuator ports, enabling extend/retract or forward/reverse operation of hydraulic cylinders or motors. The part number R900597186 corresponds to the CW110N9K4 valve cavity pattern, signaling compatibility with Rexroth’s modular valve blocks and standard mounting interfaces. Typical porting includes P (pressure supply), T (tank), and the A and B work ports, supporting standard load-sensing hydraulic circuits and straightforward integration into existing Rexroth manifolds. As part of the Rexroth 4WE family, it benefits from established sealing technology and robust construction suited for demanding industrial environments, with catalog appearances across Rexroth distributors and third-party marketplaces under the same part number. Common applications include bidirectional hydraulic control in machine tools, automation lines, and robotics systems where precise, electrically actuated hydraulic actuation is required and a compact, plug‑and‑play valve is advantageous.
