The Z4WE6D24-3X/EG24N9K4 valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is manufactured by Bosch Rexroth. It serves as a directional element in hydraulic automation, controlling flow paths in circuits that rely on compact NG6 interfaces. The valve is built in size 6 and follows the ISO 4401-03-02-0-05 porting pattern, so it can be mounted on standard sub-plates. It handles operating pressures up to 315 bar on ports P, A, and B, while the T port is limited to 210 bar to protect return lines. The design accommodates flows to 50 l/min, permitting medium-capacity actuators to be driven without excessive pressure loss. Reliable performance depends on oil cleanliness; the required condition is ISO 4406 class 20/18/15. The solenoid is energized with a nominal 24 V DC supply that draws a rated current of 1.25 A and consumes 30 W of power.
In continuous duty, the coil may remain powered at a 100 % duty cycle, and its surface temperature can rise to 120 °C, so suitable thermal spacing is necessary. Actuation commands reach the solenoid through a DIN EN 175301-803 K4 connector, which provides standardized pin alignment and robust strain relief. A concealed manual override permits spool shifting during commissioning or in emergency power loss situations without exposing moving parts. The electromagnet can switch up to 15 000 cycles per hour on direct current, allowing rapid cylinder indexing in high-throughput machines. Environmental protection meets IP65, enabling location on manifolds exposed to dust, oil mist, and low-pressure wash-down. The mean time to dangerous failure is 150 years, giving designers a wide safety margin for mission-critical installations.
