The 4WE6G6X/EG24N9/62SO43A-1221A valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow in automated machinery. It mounts on sub-plates with the ISO 4401-03-02-0-05 porting pattern, ensuring dimensional interchangeability with standard manifolds. A 24 V DC solenoid drives the spool and draws a nominal 30 W, so electrical panels can size power supplies accordingly. The design supports a 100 percent duty cycle, allowing the coil to remain energized without forced pauses. When powered from direct current the body passes up to 80 l/min, and it tolerates 350 bar on pressure ports A, B, and P, which lets it work in high-pressure circuits. Return flow on port T can reach 210 bar in direct-current service, and the hydraulic medium must meet ISO 4406 cleanliness class 20/18/15 to protect internal clearances.
For installations that energize the solenoid with alternating current, the maximum flow rate is 60 l/min, and tank port T is limited to 160 bar in that mode. The valve accepts oils as thin as 2.8 mm²/s and as thick as 500 mm²/s, giving users latitude in selecting fluids or operating at varying temperatures. Ambient air can range from −20 °C to +50 °C, so the component suits unheated or moderately warm machine halls, while the nitrile-sealed fluid path tolerates hydraulic oil between −20 °C and +80 °C. These temperature limits help keep seal elasticity and prevent cavitation. Together the viscosity window, temperature span, and flow ratings define stable switching behavior across typical industrial duty cycles.
