R900561278 Bosch Rexroth 4WE6E6X/EG24N9K4- Directional spool valves

The Bosch Rexroth 4WE6E6X/EG24N9K4 (Part No. R900561278) is a direct-operated directional spool valve engineered to govern the direction, start, and stop of fluid flow in industrial hydraulic systems. Designed for Size 6 (NG6 / ISO 4401-03 / CETOP 03) subplate mountings, this valve utilizes heavy-duty wet-pin 24V DC solenoids with detachable coils, allowing easy maintenance and coil replacement without opening or breaching the pressure-sealed fluid chamber.

Featuring an "E" spool symbol configuration (4-way, 3-position, spring-centered with all ports closed in the center position), this valve ensures secure locking of hydraulic actuators in their resting position. Its heavy-duty cast-iron body with fluid-optimized internal flow paths guarantees minimal pressure drop, high performance limits, and long service life under high-frequency operational cycles.
