The Z4E6E5320AG24N9Z4S06 valve from Bosch Rexroth belongs to the WE Directional Spool Valves series and directs hydraulic flow in automated circuits. It is built in nominal size 6, so it fits standard CETOP 03 manifold cavities while keeping envelope dimensions compact. The mounting interface follows porting pattern ISO 4401-03-02-0-05, which allows drop-in replacement in modular stacks. When energized, the valve passes up to 80 l/min without exceeding the rated 350 bar at ports A, B, or P, giving it capacity for medium-pressure actuators. Continuous 100 percent duty cycle capability permits the solenoid to remain powered during long positioning cycles common in machine tools. The coil operates on 24 V DC; a ±10 percent voltage tolerance maintains shift force under fluctuating supplies. At that voltage it draws 1.25 A, producing 30 W of nominal power to move the spool reliably under full pressure.
The direct-current winding is built to insulation class F, so dielectric strength is preserved even as the coil surface approaches its 120 °C limit during extended energization. A concealed manual override identified by code N9 lets maintenance staff shift the spool mechanically, and the feature withstands 50 bar back pressure to tank when used. Normal return flow can reach 210 bar at port T, matching manifold systems that run elevated back-pressure circuits. To avoid wear and sticking, the hydraulic fluid must meet cleanliness level 20/18/15 per ISO 4406. Reliability figures are high; an MTTFd of 300 years reflects robust design of the electrical and hydraulic parts. Together these parameters allow the valve to perform consistent directional control in industrial presses, plastics machinery, and general automation where rapid cycle times and high availability are required.
