The 4WE6Q25-6X/EG24N9K4/A12 valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series and directs hydraulic flow in automated machinery. It is energized with a nominal voltage of 24 V DC to match common control supplies, and the solenoid draws a rated current of 1.25 A, defining the load seen by the driver card. Nominal power consumption is 30 W, so enclosure ventilation must dissipate that heat. Continuous service is supported by a 100 % duty cycle, allowing the spool to stay shifted indefinitely. The coil surface can reach 120 °C, a figure that guides conductor insulation selection. Electrical connection is handled through a DIN EN 175301-803 K4 plug for fast maintenance swaps. An IP65 enclosure rating resists dust and low-pressure water jets, allowing installation on exposed machinery. The armature can shift up to 4.2 times per second in direct-current operation, supporting rapid directional changes in servo-controlled systems.
The valve passes up to 80 l/min of hydraulic fluid, keeping pressure loss low in medium-flow circuits. Ports P, A, and B tolerate 350 bar, enabling use in high-pressure presses, while the tank port withstands 210 bar and therefore dictates return-line component selection. A standardized ISO 4401-03-02-0-05 mounting interface lets the unit bolt to common subplates, and fastening torque of 7 Nm ensures proper seal compression without damaging threads. A concealed manual override designated N9 allows technicians to shift the spool during power loss for system purging or setup tasks. With two solenoids the assembly weighs 1.95 kg, so manifolds can remain lightweight. These mechanical and hydraulic characteristics combine to provide precise, reliable directional control in automated hydraulic circuits.
