The 4WE6D73-6X/EG24N9K4QMAG24/A12 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow paths in automated machinery and is driven by a 24 V DC coil so it integrates with common control supplies. The solenoid draws a rated current of 1.25 A and consumes 30 W, giving predictable power budgeting for the electrical cabinet. A voltage tolerance of ±10 % lets the coil function correctly during minor line variations, while a duty cycle of 100 % ED supports continuous energization without thermal cycling. The winding is built to Class F insulation, and the surface of the coil may reach 120 °C, details that define safe thermal limits for enclosure design. Electrical connection is achieved through a plug that follows DIN EN 175301-803, ensuring quick interchange with standard harnesses.
For the hydraulic side, the valve permits a maximum operating pressure of 350 bar on ports A, B, and P so it suits high-pressure circuits, while the tank port tolerates up to 210 bar to accommodate back-pressure conditions. Manually overriding the spool is possible as long as tank pressure stays below 50 bar, enabling service positioning without overpowering the mechanism. The unit accommodates flow rates up to 80 l/min, allowing mid-frame actuators to cycle at practical speeds. A porting pattern of ISO 4401-03-02-0-05 matches common sub-plates, and IP65 protection keeps dirt and water from the solenoid when a mating connector is installed. Switching can occur at up to 4.2 cycles per second to meet rapid control demands, and the design limits switch-off overvoltage to 500 V to protect driver electronics.
