REXROTH

Bosch Rexroth 4WE6E6X/EW110N9K4 R900558641 is a direct operated directional spool valve designed for reliable start, stop, and direction control of hydraulic oil flow in industrial hydraulic systems. As part of the Bosch Rexroth WE6 series, it offers dependable switching performance, compact dimensions, and long service life for demanding hydraulic applications.

This valve is manufactured in NG6 (Size 6 / CETOP 3 / ISO 4401-03) configuration with subplate mounting. It features spool symbol E, a 4/3-way directional function, and a 110V AC wet-pin solenoid with detachable coil for easy maintenance and continuous-duty operation.

The component series 6X provides compatibility with standard WE6 installation dimensions while supporting maximum operating pressures up to 350 bar. The valve delivers reliable hydraulic flow control for both machine automation and hydraulic power transmission systems.

The model is equipped with concealed manual override (N9), allowing emergency manual actuation during maintenance or electrical failure. The K4 electrical connector complies with EN 175301-803, providing secure electrical connection and convenient installation in industrial environments.

Typical applications include hydraulic power units, machine tools, injection molding machines, hydraulic presses, metal forming equipment, material handling machinery, test benches, and industrial automation systems requiring accurate directional control of hydraulic actuators.

The direct operated spool design provides smooth switching characteristics, stable operation, and repeatable control performance. Wet-pin AC solenoids are pressure-tight and permit coil replacement without opening the hydraulic chamber, reducing maintenance time and minimizing downtime.

For optimum service life, Bosch Rexroth recommends clean hydraulic fluid and proper filtration to reduce spool wear and maintain stable switching performance throughout continuous operation.
