The 4WE6E6X/EG205N9K4/N15 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs pressurized fluid to selected actuator ports in automated hydraulic equipment. It is built in size 6 to fit compact manifolds while still allowing the required flow area for medium power circuits. A wet-pin high-power solenoid shifts the spool, and the coil accepts 205 V DC within a ±10 % range so voltage variation on the supply bus does not disturb actuation. During continuous energization the winding draws 0.16 A and dissipates 30 W, and the coil is rated for a 100 % ED duty cycle so it can remain energized without thermal rest periods. Wiring is made through a DIN EN 175301-803 connector, which seals to the housing with an IP65 rating to block dust and low-pressure water jets.
The valve mounts to sub-plates that follow NFPA T3.5.1 D03 dimensions, and its porting aligns with the ISO 4401-03-02-0-05 pattern so technicians can replace it without re-machining the base. A concealed manual override lets maintenance staff shift the spool mechanically when power is absent and protects the button from dirt or accidental contact during operation. In service, the unit handles flows up to 80 l/min and withstands 350 bar on pressure, supply, and work ports while the tank line is limited to 210 bar in direct current operation; these limits define the envelope for safe circuit design. A throttle insert of 1.5 mm diameter in the A and B lines moderates surge flow and stabilizes actuator motion at small displacements.
