The 4WE6X7-6X/EG24N9K4 directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and switches hydraulic flow paths in automated machinery. It runs on a nominal voltage of 24 V DC so that standard control supplies can energize the coil, and a rated current of 1.25 A provides stable magnet force without overloading drivers. The coil draws 30 W of nominal power, balancing energy use with the force required to move the spool. Continuous holding is permitted by a 100 % ED duty cycle, avoiding heat-related shutdowns during long service. The coil surface may reach 120 °C, which defines thermal clearances for nearby components, while insulation class F protects the winding from this heat. Wiring is completed through a DIN EN 175301-803 K4 connector for quick installation, and the assembled unit meets IP65 to resist dust and low-pressure water jets in industrial environments.
Nominal size 6 keeps the valve compact for manifold mounting, and the flow paths follow the ISO 4401-03-02-0-05 porting pattern to fit common subplates. An NFPA T3.5.1 R2-2002 D03 interface provides equivalent compatibility for North American bases. Working ports withstand up to 350 bar so the valve can control high-pressure actuators, while the tank port limit of 210 bar sets the safe return-line pressure. A maximum flow of 80 l/min suits medium-sized cylinders and motors at rated pressure. NBR seals handle standard mineral oils and maintain leak-free service life. A concealed manual override identified as N9 allows technicians to shift the spool mechanically without exposing the mechanism to contamination.
