The 4WE6D6X/OFEG24N9/62SO43A-1221A valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series. It directs pressurized fluid to cylinders or motors in automated hydraulic equipment. The unit mounts to subplates following the ISO 4401-03-02-0-05 porting pattern, ensuring interchangeability with common manifolds. Actuation is provided by a high-power wet-pin solenoid that runs on 24 V DC; the solenoid draws 1.25 A and consumes 30 W to shift the spool reliably. An F-class insulation system and a maximum coil surface temperature of 120 °C protect the winding during continuous duty. Electrical supply can deviate by ±10 % from nominal without loss of function, and the design supports a 100 % duty cycle so the valve may remain energized indefinitely.
Hydraulic ratings allow line ports P, A, and B to withstand 350 bar while the tank port handles up to 210 bar, permitting use in high-pressure circuits. The flow path is sized for 80 l/min, balancing response speed with pressure drop. System oil must meet ISO 4406 cleanliness level 20/18/15 to minimize spool wear and sticking. Two solenoids bring the assembled weight to 1.95 kg, light enough for manifold stacking. A concealed manual override lets technicians shift the spool without energizing the coil, and a locating hole to ISO 8752-3x8-St provides accurate positioning on the mounting face. The concealed override design also shields the mechanism from contaminants.
