The 4WE6G73A6X/EG24N9K73L/A12/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. This unit directs hydraulic fluid in automated machinery and comes in nominal size 6, which determines the port dimensions and overall flow capacity. The internal spool follows symbol G73 to establish the required flow paths for the connected A, B, P, and T ports. Actuation is driven by a 24 V DC solenoid that draws 1.25 A and consumes 30 W, while a 100 % ED rating allows the coil to remain energized continuously without thermal overload. Smooth switching is achieved by the A12 mode, reducing pressure shocks during directional changes. A concealed N9 manual override permits local movement of the spool when power is unavailable. Electrical hookup uses a 4-pin M12×1 connector labeled K73L, and an IP65 enclosure rating protects the valve against dust ingress and low-pressure water.
The housing includes an ISO 8752-3×8-St locating hole with a locking pin to secure the valve on a subplate and maintain alignment under vibration. During operation the coil surface may reach up to 120 °C, so mounting must provide adequate heat dissipation. The hydraulic section handles continuous flows up to 80 l/min and withstands 350 bar on ports A, B, and P, giving the valve sufficient capacity for medium-pressure circuits. Back-pressure on the tank port can be as high as 210 bar in direct-current service without impairing function. These pressure and temperature limits, combined with the previously mentioned smooth switching and continuous duty capability, define the working envelope for consistent performance in industrial hydraulic automation.
