The 4WE6J73-6X/EG24N9K4/A12V valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. Designed to shift hydraulic flow between work ports in automated machinery, it is energized by a 24 V DC solenoid drawing a nominal power of 30 W and a rated current of 1.25 A. Class F coil insulation allows the winding to operate safely up to a surface temperature of 120 °C, while a 100 % duty cycle supports continuous service without planned cool-down periods. The unit tolerates supply variations of ±10 %, so voltage dips or rises within that band do not affect switching reliability. A DIN EN 175301-803 K4 connector provides standardized electrical termination for quick replacement in the field.
The valve body follows the ISO 4401-03-02-0-05 port pattern, enabling direct mounting on subplates common to size 03 circuits. An IP65 enclosure rating protects internal components against dust and low-pressure water jets when the mating connector is properly seated. The spool can switch at up to 4.2 cycles per second, giving fast response for high-repeat operations, and accommodates a maximum flow of 80 l/min in direct current service. Operating pressure reaches 350 bar on the P, A, and B ports, while the T port is limited to 210 bar to safeguard return-line components. Fluid temperatures may rise to 80 °C when FKM seals are fitted, and those seals also provide chemical resistance to many synthetic oils.
