The 4WE6E6X/EW110NK4/V/62CSA directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation circuits where reliable flow routing is required. It fits the nominal size 6 envelope, and its porting pattern ISO 4401-03-02-0-05 allows mounting on common subplates without adapter blocks. The unit tolerates operating pressures up to 350 bar, giving it compatibility with high-pressure pumps and cylinders, while a maximum flow of 60 l/min keeps pressure losses within limits. Actuation is handled by a solenoid coil rated at 110 V, 50/60 Hz; the design accepts a ±10 % voltage swing to accommodate supply variation. An inrush demand of 220 VA must be provided during energization, and the 100 % ED duty cycle means the coil may remain powered indefinitely without surpassing thermal limits.
After the armature reaches its end position, the holding power drops to 50 VA, reducing heat generation during steady operation. The valve’s tank port is specified for 160 bar so return-line surges do not cause casing distortion. An IP65 housing prevents dust ingress and water jets from affecting internal components, and wiring is completed through a DIN EN 175301-803 K4 connector that supports fast coil replacement. System oil must meet ISO 4406 cleanliness class 20/18/15 to avoid spool scoring and leakage. A switch-off overvoltage limit of 500 V safeguards the insulation when the coil is de-energized. Precise manifold alignment is achieved with a locating hole fitted with a locking pin conforming to ISO 8752-3×8, ensuring the directional element seats correctly in compact hydraulic stacks.
