The 4WE6J6X/EW110N9DK25/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series and is intended to route pressurized fluid in hydraulic automation systems. Valve size 6 establishes the flow passage area, while the ISO 4401-03-02-0-05 mounting interface allows direct installation on standard CETOP 3 subplates. A solenoid designed for 110 V at 50/60 Hz performs the shifting action, and a 100 % ED duty cycle lets the coil stay powered continuously. Holding power is limited to 50 VA to reduce heat and energy use. Wiring is completed through a central DK25 five-pole connector, and an IP65 housing keeps dust and water jets from reaching internal parts. A concealed N9 manual override provides emergency actuation without dismantling covers, and a locating hole with an ISO 8752-3×8 locking pin prevents movement of the body during maintenance.
The hydraulic section tolerates 350 bar on pressure and service ports P, A, and B, while the tank port is rated for 160 bar, enabling use in high-pressure circuits that return fluid through restricted lines. Maximum flow reaches 60 l/min so medium-capacity cylinders or motors receive adequate volume. The spool can shift up to two times per second; this switching frequency balances response speed with acceptable coil heating. Fluids may operate between −20 °C and +80 °C to cover cold-start and elevated-temperature duty cycles, and the coil surface may rise to 120 °C during prolonged energization, requiring nearby components to withstand that heat. Together these limits define safe operating conditions and help maintain reliable service life in automated hydraulic machinery.
