The 4WE6D6X/OFEW110N9DK25L/B12 valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth. It directs hydraulic flow by sliding a D-coded spool into predefined positions held by a detent, ensuring lines remain in the selected state without continuous power. Actuation comes from a wet-pin solenoid with a detachable coil, allowing quick replacement in service environments. The coil is designed for a 110 V AC supply at either 50 or 60 Hz, and it draws 0.52 A at 50 Hz during steady operation while sustaining a 100 % duty cycle so long shifts do not overheat the windings. A DK25L five-pole connector provides the electrical interface and permits rapid field wiring. For local service actions, a concealed N9 manual override lets technicians shift the spool without energizing the solenoid. The assembly weighs 1.95 kg with both solenoids attached, making it light enough for manifold mounting without additional supports.
Installation uses the ISO 4401-03-02-0-05 pattern, so the valve can bolt directly onto standard size 6 subplates. Hydraulic passages tolerate 350 bar on ports P, A, and B, while the tank port is limited to 160 bar to protect return-line components. When fully open it passes up to 60 l/min, matching medium-flow circuits in machine tools and presses. An IP65 enclosure rating shields the coil and terminals from dust and low-pressure water jets, allowing reliable operation in typical plant wash-down areas. At 60 Hz the coil current falls to 0.39 A, which reduces heat generation in regions that use this frequency. A 1.2 mm throttle insert in port B moderates flow transitions to curb pressure shocks downstream. Together these characteristics let the valve control direction, contain system pressure, and maintain serviceability within compact hydraulic manifolds.
