The 4WE6HA6X/EG24N9K72L directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automation systems that require rapid and reliable switching between actuator circuits. The valve employs an H spool to establish its switching logic and mounts on subplates that follow the ISO 4401-03-02-0-05 porting pattern. With nominal size 6 passages it can carry up to 80 l/min in direct-current operation. The energized solenoid draws 1.25 A from a 24 V DC supply, and the coil accepts a ±10 % voltage swing without performance loss. Nominal electrical demand is 30 W, and the winding is designed for a 100 % duty cycle so continuous energization does not exceed thermal limits.
A concealed N9 manual override lets technicians shift the spool mechanically when power is absent. Electrical hookup is provided by a 4-pole M12×1 connector coded K72L, and the 24 V DC feed is assigned to pin 4 to match standard wiring harnesses. The housing meets IP65, protecting internal parts against dust and low-pressure jets encountered in most machinery cells. Hydraulic limits reach 350 bar on the P, A and B service ports, while the T return port withstands 210 bar during direct-current actuation. These ratings support high-pressure circuits without auxiliary relief devices. A single-solenoid valve body weighs 1.45 kg, minimizing manifold stress and easing replacement during scheduled maintenance.
