The 4WE6J73-6X/EG24N9DK24L/A12/62 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery where rapid and precise actuation is required. A maximum flow capacity of 80 l/min lets the valve service medium-size actuators without excessive pressure loss, and its ports withstand 350 bar on lines P, A, and B to suit high-pressure circuits. Continuous operation is possible because the solenoid is rated for a 100 % duty cycle. The coil is energized at 24 V DC so standard control supplies can drive the unit, while nominal power consumption of 30 W limits electrical loading. Voltage tolerance of ±10 % maintains performance during supply fluctuations. Electrical termination is through a DK24L connector with an M12 x 1, 4-pole interface, and a concealed N9 manual override lets technicians shift the spool during commissioning or power loss.
Tank port pressure is limited to 210 bar to protect return lines and reservoirs, and the housing matches mounting pattern ISO 4401-03-02-0-05 for direct installation on standard subplates. An IP65 protection class prevents dust ingress and water jets from affecting the solenoid, while system cleanliness of ISO 4406 code 20/18/15 is required to reduce wear and maintain spool accuracy. Insulation class F permits winding temperatures aligned with higher thermal limits, and a locating hole with a locking pin per ISO 8752-3x8 secures the valve on the manifold against vibration. The coil surface may reach 120 °C, so adjacent components must tolerate that heat, and a switching frequency of 4.2 cycles per second defines the maximum rate for reliable directional changes in fast control loops.
