The 4WE6X6-6X/EW110N9K4 valve is part of the WE Directional Spool Valves series from Bosch Rexroth and is used to shift hydraulic flow between work ports in automated machinery. Its size 6 construction fits systems designed around the ISO 4401-03-02-0-05 mounting interface, so it bolts directly onto standard subplates without adapters. A maximum operating pressure of 350 bar on ports P, A, and B allows the valve to handle high-pressure supply lines, while the tank port is limited to 160 bar to protect return plumbing. The spool passages support up to 60 l/min, defining the flow capacity available to downstream actuators. Electrical actuation is managed by a 110 V AC coil that accepts either 50 Hz or 60 Hz line frequency, and a ±10 % voltage tolerance keeps performance stable during supply fluctuation. Switch-on power peaks at 220 VA to create the magnetic force needed for rapid shifting; once energized, the holding power drops to 50 VA to reduce heat and energy use.
A continuous duty cycle of 100 % ED permits the solenoid to remain powered indefinitely without planned cooling pauses, and the rated current of 0.39 A at 60 Hz quantifies the steady electrical load drawn from the control circuit. The coil’s surface may reach 120 °C, so surrounding components must be arranged to accommodate that temperature limit. Protection class IP65 is achieved when the DIN EN 175301-803 (K4) connector is properly installed, sealing the enclosure against dust ingress and low-pressure water jets commonly present in industrial plants. The same K4 connector standardizes wiring practices, simplifying replacement units and field service. A concealed manual override identified by code N9 lets maintenance personnel shift the spool mechanically during commissioning or in the event of electrical failure without exposing the mechanism to accidental activation.
