The Z4WE6E68-3X/EW110N9K4QMAG24 directional valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is manufactured by Bosch Rexroth. It directs hydraulic oil between pressure, actuator, and return lines in automated machinery. The unit is built in valve size 6, allowing compact installation while still supporting a nominal flow rate of 50 l/min. It bolts to manifolds that follow the ISO 4401-03-02-0-05 interface so users can swap it with other size-6 components without re-machining. A solenoid energized by 110 V AC at 50 or 60 Hz moves the spool; during energization the coil draws 220 VA and then settles to 50 VA holding power, a profile that minimizes heat once motion is complete. Continuous operation is permitted because the coil is rated for a 100 percent duty cycle (S1). Up to 315 bar can be applied to ports P, A, and B, and the spool may shift up to 7,200 cycles per hour without exceeding its electrical limits.
Electrical connection is made through a DIN EN 175301-803 plug coded K4, simplifying coil replacement and ensuring pin compatibility with common cable assemblies. Control cabinets can track spool travel because position A is monitored via a contact that is energized by a separate 24 V DC supply. To protect insulation during de-energization, the solenoid withstands switch-off transients up to 500 V. The return line may carry as much as 160 bar, and the manual override may be operated safely while tank pressure stays below 50 bar. An IP65 enclosure rating, achieved once the connector gasket is in place, resists dust ingress and water jets encountered on mobile or wash-down equipment. These mechanical and electrical limits allow the valve to integrate into automated hydraulic systems where quick cycle times, monitored actuation, and reliable sealing are required.
