The 4WE6J6X/EG220N9DK25L/B10 is produced by Bosch Rexroth within the WE Directional Spool Valves series for directing hydraulic flow in automated machinery. It is energized with 220 V DC, so installation in direct-current control cabinets is straightforward. A voltage tolerance of ±10 % allows the coil to remain functional despite moderate supply deviations. The valve draws a rated current of 0.14 A, which defines the sizing of protective fuses and wiring. Its nominal power consumption is 30 W, limiting heat buildup during continuous duty. Electrical connection is provided by a DK25L five-pole plug, simplifying field replacement. A duty cycle of 100 % (S1) means the solenoid can stay energized without imposed cool-down intervals. Maximum switching frequency is 4.2 cycles per second, setting the upper limit for rapid directional changes. A concealed manual override marked N9 lets maintenance staff shift the spool without energizing the coil.
The valve carries an IP65 enclosure rating, allowing installation in dusty or wet plant areas without additional covers. Hydraulic flow up to 80 l/min can pass through the spool in direct current service, supporting medium-size actuator circuits. Working ports P, A, and B withstand operating pressures up to 350 bar, enabling high-pressure closed-center systems. The tank port tolerates 210 bar, so back-pressure in return lines does not compromise sealing. A porting pattern conforming to ISO 4401-03-02-0-05 fits standard CETOP 3 sub-plates. A throttle orifice of 1.0 mm in the pressure port moderates inrush flow to reduce shock. The coil surface temperature can reach 120 °C in service, a limit that guides selection of adjacent components and insulation materials.
