The 4WE6H73-6X/EG24N9K4/A12/62 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. The design follows size 6 dimensions, giving a defined envelope for compact subplate mounting. It attaches to an ISO 4401-03-02-0-05 pattern so it integrates with standard manifolds. The solenoid coil draws 30 W of direct-current power to shift the spool. A nominal supply of 24 V DC supports common control voltages, and the coil tolerates ±10 % variation without losing function. Continuous energization is permitted because the duty cycle is rated at 100 % ED.


The flow paths handle up to 80 L/min, covering medium-capacity circuits. Ports P, A, and B withstand 350 bar, while port T endures 210 bar during direct-current operation. The spool can switch 4.2 times per second, allowing rapid cycling. Coil surface temperature is limited to 120 °C, and Class F insulation protects the windings against heat. An IP65 enclosure blocks dust and water jets when the connector is fitted. System oil must reach ISO 4406 20/18/15 cleanliness to prevent wear. With two solenoids installed the assembly weighs 1.95 kg, making manual installation practical.
