R900521281 Bosch Rexroth 4WE10W3X/CW230N9K4 - Directional spool valves
The Bosch Rexroth 4WE10W3X/CW230N9K4 (Part No. R900521281) is a direct-operated directional spool valve engineered to control the start, stop, and direction of fluid flow in industrial hydraulic systems. Designed to Size 10 (NG10 / ISO 4401-05 / CETOP 05) mounting standards, this valve features high-performance wet-pin AC solenoids operating at 230V AC (50/60 Hz). The sealed solenoid coils can be easily rotated or replaced without opening or breaching the pressure-tight hydraulic chamber.
Configured with a "W" spool symbol layout (4-way, 3-position configuration), it provides smooth, dependable fluid redirection for heavy manufacturing equipment, hydraulic power units, and automated machinery. Its heavy-duty cast-iron body features fluid-optimized internal passages that minimize pressure drops and maintain long-term reliability under continuous high-pressure operation.
