R900594277 Bosch Rexroth 4WE10G3X/CG24N9K4 - Directional spool valves

The Bosch Rexroth 4WE10G3X/CG24N9K4 (Part No. R900594277) is a direct-operated directional spool valve engineered to control the start, stop, and direction of fluid flow in high-performance industrial hydraulic systems. Designed for Size 10 (NG10 / ISO 4401-05 / CETOP 05) standard subplate mountings, this valve features heavy-duty wet-pin 24V DC solenoids. The detachable solenoid coils can be rotated or replaced easily without opening or disturbing the pressure-sealed hydraulic chamber.

Configured with a "G" spool symbol layout (4-way, 3-position, spring-centered setup), it connects line P to line T while lines A and B are blocked in the center position. This design enables pump pressure recirculation/unloading during neutral idle while maintaining static hydraulic holding pressure on lines A and B to lock actuators securely in place. Its heavy-duty cast-iron body with fluid-optimized internal flow passages ensures low pressure drop, high performance power limits, and long-term durability under continuous production cycles.
