The Z4WE6E68-3X/EG24N9K4QMAG24 spool valve is part of the Z4WE Solenoid Actuation Spool Valves series from Bosch Rexroth. Designed to route pressure and return lines in hydraulic automation, it follows the ISO 4401-03-02-0-05 mounting pattern so it mates with standard subplates. The assembly accepts hydraulic fluid with a cleanliness level of 20/18/15 per ISO 4406, which limits particulate wear on the spool and seats. It withstands 315 bar on ports P, A, and B, while port T is limited to 210 bar, allowing it to serve both pressure and tank circuits without additional check valves. The valve passes up to 50 l/min so actuators with moderate flow demand remain responsive. Solenoid control relies on a 24 V DC input that draws 1.25 A within a ±10 % voltage band to maintain consistent actuation force. These electrical limits let the valve integrate with common PLC power supplies used across mobile and industrial machinery.
The dual-solenoid configuration consumes 30 W during steady operation and can run continuously because the duty cycle is 100 %. Even under prolonged energization, the coil surface temperature may reach 120 °C, a level that defines enclosure spacing and wiring insulation. The electrical interface is a 3-pole (2 + PE) DIN EN 175301-803 plug, simplifying field replacement and grounding. An IP65 housing protects the coil and core tube against dust ingress and water jets, making the valve suitable for exposed machine frames. During de-energization, internal suppression must accommodate up to 500 V of switch-off overvoltage, and the armature can cycle as fast as 15 000 times per hour for rapid directional changes. The two solenoids bring the total weight to 1.6 kg so a standard manifold can support the assembly without extra brackets. These parameters outline the electrical load, thermal behavior, and environmental resistance required for dependable spool positioning in demanding hydraulic sequences.
