The 4WE6U6X/EG24N9K4SO43A-1755 is a directional spool valve manufactured by Bosch Rexroth within the WE Directional Spool Valves series for controlling hydraulic actuators in automated machinery. It is built around nominal size 6 ports and fits the ISO 4401-03-02-0-05 mounting pattern, which corresponds to the NFPA D03 interface, so it can be installed on standard sub-plates. The valve passes up to 80 L/min of oil and tolerates 350 bar on pressure, A, and B ports while the tank line endures 210 bar. Electrical actuation is supplied at 24 V DC; the coil draws a rated 1.25 A and absorbs 30 W during operation. These figures allow the unit to shift the spool rapidly without overheating or voltage sag in mobile or stationary power packs.
A continuous 100 % duty cycle lets the solenoids remain energized indefinitely, supporting closed-loop control cycles. Connection to the machine harness is made through a K4 plug that follows DIN EN 175301-803, and the housing carries an IP65 rating that blocks dust and low-pressure jets when a suitable cable gland is fitted. The winding system meets insulation class F for reliable thermal endurance. A concealed N9 manual override permits local actuation, with the override rated for 50 bar tank pressure during troubleshooting. The complete valve with two solenoids weighs 1.95 kg, providing a compact and easily handled component for manifold layouts.
