R900503425 Bosch Rexroth 4WE10H3X/CW230N9K4 - Directional spool valves
The Bosch Rexroth 4WE10H3X/CW230N9K4 (Part No. R900503425) is a direct-operated directional spool valve designed to govern the direction, start, and stop of hydraulic fluid flow in industrial applications. Built to Size 10 (NG10 / ISO 4401-05 / CETOP 05) standards, this valve features high-performance wet-pin AC solenoids operating at 230V AC (50/60 Hz), with detachable coils that can be easily serviced or rotated without breaching the pressure-sealed fluid chamber.
Featuring an "H" spool symbol configuration (where all ports A, B, P, and T are connected in the central position), this 4-way, 3-position valve provides effective pump unloading and system pressure relief during neutral idle. Its heavy-duty cast-iron body with fluid-optimized internal passages ensures minimal pressure loss, reliable spool shifting, and exceptional longevity under demanding continuous-duty operations.
