The 4WE6U12-6X/EW110N9K4 valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where electrically shifted flow control is required. It uses nominal size 6 passages to direct oil through a compact manifold, and the ISO 4401-03-02-0-05 mounting interface matches standard subplates for quick installation. A maximum operating pressure of 350 bar on ports P, A, and B lets the unit manage high-pressure circuits, while a peak flow rate of 60 l/min supports medium-speed cylinder or motor actuation. The solenoid is rated at 110 V AC on 50 or 60 Hz supplies, and it draws 220 VA at switch-on to shift the spool before dropping to a 50 VA holding level to reduce heat and energy use. Operation remains stable when the supply varies within ±10 percent of nominal voltage.
A 100 percent duty cycle allows the coil to stay energized continuously without thermal damage, assisted by insulation class H windings that withstand elevated temperatures. Wiring is completed through a 3-pole DIN EN 175301-803 connector, and the assembled envelope achieves IP65 protection so the valve resists dust ingress and water jets. A concealed manual override enables emergency spool actuation yet prevents accidental use during normal service. The tank port tolerates up to 160 bar, protecting the return line from pressure spikes, and the mechanism can switch up to two times per second to suit moderate cycling demands.
