The 4WE6J6X/EW110RN9DK6L/B10 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressure and return flow between actuator ports in hydraulic automation systems. The valve mounts to subplates machined to the NFPA T3.5.1 R2-2002 D03 pattern, and its port face follows ISO 4401-03-02-0-05, allowing direct swap with other D03 devices. Channels A, B, and P accommodate working pressures up to 350 bar, while the tank line accepts 160 bar. A maximum flow capability of 60 l/min supports medium displacement cylinders without excessive pressure drop. A throttle insert with a 1.0 mm orifice is installed in port P to limit surge when the spool shifts. The N9 option adds a concealed manual override for setup tasks. An IP65 housing shields the solenoid assembly against dust ingress and water jets encountered on industrial machinery.
Electrical actuation is handled by a 110 V, 50/60 Hz solenoid that draws 0.34 A during steady operation. Initial energization requires 220 VA switch-on power, after which the coil holds the spool with 50 VA to reduce heat and consumption. A 100% S1 duty rating permits the valve to remain energized continuously without cooling intervals. Class H insulation and a permissible coil surface temperature of 120 °C ensure thermal stability during long shifts. Power reaches the coil through a 7-pole DIN EN 175201-804 connector designated DK6L, providing secure mating and strain relief. These electrical features complement the hydraulic ratings described earlier and equip the valve for dependable service in automated presses, machine tools, and material handling stations.
