The Rexroth 4WE10D5X/OFEG220N9K4/V is a high-performance, solenoid-operated directional spool valve designed for reliable control in hydraulic systems. As a direct-operated valve of size 10 (NG10), it conforms to the ISO 4401 mounting standard, ensuring easy integration and interchangeability. This model features a “D” spool configuration, which blocks all ports (P, A, B, T) in the neutral, spring-centered position. The valve is actuated by powerful 220V AC solenoids and includes a detent (E), allowing the spool to remain in its last switched position without continuous power to the solenoid. It is equipped with FKM (Viton) seals, making it suitable for a wide range of hydraulic fluids, including mineral oils and phosphate esters. The concealed manual override (OF) provides an option for manual operation during setup or power failure.
