The 4WE6J73-6X/EG12N9K40/A12SO43A-1799A valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated equipment. It is built in size 6 and follows the ISO 4401-03-02-0-05 porting pattern for manifold mounting. The hydraulic section withstands operating pressures up to 350 bar, while the tank port tolerates 210 bar during direct-current switching. Flow capacity reaches 80 l/min under those same conditions. Consistent behavior is achieved with fluids that remain between 2.8 and 500 mm²/s in viscosity and -20 to +80 °C in temperature.
The integrated solenoid coil is rated for 12 V DC and draws 2.5 A through a Deutsch DT04-2PA two-pin connector. IP69K ingress protection shields the housing against high-pressure water and dust, and a concealed N9 manual override allows spool actuation without power. Option A12 provides an extended switching time for smoother transitions. The assembly must operate with oil cleanliness no worse than ISO 4406 class 20/18/15 to avoid premature wear. Total mass is 1.95 kg, which simplifies installation and service.
