The 4WE6J6X/EG24N9DK25L2SO43A-1778 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and serves to route hydraulic flow in automated machinery. It follows the ISO 4401-03-02-0-05 (D03) porting pattern so it bolts to common sub-plates without adapter blocks. A maximum operating pressure of 350 bar on ports A, B, and P enables control of high-pressure circuits, while a peak flow of 80 L/min meets the demand of medium-sized actuators. The coil is energized with 24 V DC at a rated current of 1.25 A, drawing 30 W of electrical power from the control supply. Continuous 100 percent duty means the valve can cycle without pause during extended production. The coil surface temperature is limited to 120 °C to protect the winding insulation.
The enclosure carries an IP65 rating, shielding internal parts from dust and low-pressure water jets, and insulation class F allows the windings to tolerate elevated operating heat. Port T is rated for 210 bar so the unit handles high return-line back-pressure. A concealed manual override gives technicians a way to shift the spool during setup, and it can be actuated safely when tank pressure is up to 50 bar. The electromagnetic circuit withstands switch-off overvoltages as high as 500 V, reducing stress on control electronics. Hydraulic oil must meet cleanliness class 20/18/15 under ISO 4406 to maintain reliable spool movement. With two solenoids installed the valve weighs 1.95 kg, which aids straightforward mounting onto manifold assemblies.
