The Z4WE6E68-3X/EW110N9K4/V spool valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is produced by Bosch Rexroth for directional control in hydraulic automation. It uses a nominal coil voltage of 110 V at 50/60 Hz to interface with standard control supplies. At energization the coil draws 220 VA, then settles to a 50 VA holding power to curb energy loss. A continuous duty rating of 100 % ED permits uninterrupted actuation, while a maximum switching frequency of 7,200 cycles per hour supports fast machine sequences. The coil surface can reach 120 °C, so adjacent components must tolerate that heat. Electrical connection is made through a DIN EN 175301-803 plug, and a concealed manual override lets technicians shift the spool without energizing the solenoid.
The hydraulic section withstands 315 bar on pressure ports and up to 160 bar on port T when powered by alternating current, enabling use in high-pressure circuits. The valve accommodates flows to 50 L/min within the ISO 4401-03-02-0-05 port pattern, simplifying manifold design and ensuring predictable line velocities. System fluid must meet ISO 4406 cleanliness class 20/18/15 to prevent abrasive wear between spool and bore. FKM elastomer seals provide chemical and temperature resistance for common hydraulic oils. When the mating connector is secured, the assembly reaches an IP65 protection class for wash-down environments. The coil tolerates switch-off overvoltages up to 500 V, protecting driver electronics from inductive transients.
