The Bosch Rexroth 4WE 6 G62/EW230N9K4 is a high-performance, direct-operated directional spool valve designed for reliable control in hydraulic systems. This solenoid-actuated valve is used to start, stop, and direct fluid flow. As a size 6 (NG6) valve, it adheres to the CETOP 3 and NFPA D03 mounting standards, ensuring easy integration and interchangeability. The ‘G’ spool configuration provides a 4-way, 3-position function with a closed center, meaning all ports (P, A, B, T) are blocked in the neutral position. This feature is ideal for applications requiring an actuator to be hydraulically locked in place when the valve is de-energized. The wet-pin AC solenoid ensures long service life, quiet operation, and can be replaced without opening the pressure-tight chamber.
