The Rexroth R900920691 4WE6D6X/OFEG220N9K4 is a high-performance, direct-operated directional spool valve designed for controlling the start, stop, and direction of fluid flow in hydraulic systems. This size 6 (NG6) valve conforms to the CETOP 3 mounting standard, ensuring easy integration and interchangeability. It features a ‘D’ spool configuration, which blocks all ports in the neutral, spring-centered position for secure load holding. The valve is actuated by a robust 220V AC wet-pin solenoid and is equipped with a detent mechanism (‘F’), which holds the spool in its last shifted position without continuous power. A concealed manual override (‘O’) is included for manual operation during setup or power failure, making it a versatile and reliable choice for various industrial applications.
