The 4WE6D6X/EW110N9K4SO43A-1809 directional spool valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and switches hydraulic flow to drive cylinders or motors in automated machines. Valve size 6 sets a compact flow section suited to space-restricted manifolds. A maximum operating pressure of 350 bar lets the unit handle high-pressure supply lines without loss of function, while a peak flow rate of 60 l/min supports medium-sized actuators. The porting pattern ISO 4401-03-02-0-05 ensures interchangeability with worldwide subplates, and the NFPA pattern T3.5.1 R2-2002 D03 offers the same benefit for North American layouts. A clamping length of 42 mm positions the body firmly in the sandwich stack, and mounting bolts must be tightened to 7 Nm to keep the seal face compressed. An IP65 enclosure rating protects the solenoid and spool chamber against dust and low-pressure water so the valve can be mounted outside a cabinet.
The solenoid is designed for 110 V operation on AC networks, and the 50/60 Hz rating allows use on either common mains frequency. Insulation class H winding material endures elevated temperatures during long energization periods, while the coil surface may reach 120 °C without damage when mounted in confined spaces. Power is supplied through a K4 connector built to DIN EN 175301-803, giving a quick-release interface for service work. A concealed manual override designated N9 lets maintenance staff shift the spool mechanically when electrical power is absent, and the mechanism resists tank pressures up to 50 bar so unintended leakage is avoided. The tank port itself is permitted to see 160 bar, enabling the valve to operate in circuits with substantial back-pressure. Together, these electrical and control features complement the hydraulic ratings introduced earlier to deliver reliable directional control in automated systems.
