The Z4WE6E53-20/AG24N9Z4S06MR directional spool valve is produced by Bosch Rexroth as part of the WE Directional Spool Valves series and is used to control flow direction in automated hydraulic circuits. It installs on subplates that follow the ISO 4401-03-02-0-05 porting pattern and matches NFPA size D03. The valve withstands a maximum operating pressure of 350 bar at ports P, A, and B, while the tank port is limited to 210 bar. Direct-current operation allows a maximum flow of 80 l/min, and the E-coded spool defines the internal flow paths for its switching positions. A switching frequency of up to 4.2 cycles per second enables rapid response, and the assembly with two solenoids weighs 1.95 kg for straightforward handling during installation.
Each solenoid operates on a nominal voltage of 24 V DC, drawing 1.25 A at a nominal power consumption of 30 W. A voltage tolerance of ±10 % accommodates common supply variations, and continuous duty at 100 % ED (S1) permits uninterrupted energization. Coil insulation meets class F requirements, and the surface temperature is allowed to reach 120 °C without damage. A concealed manual override identified as N9 lets maintenance staff shift the spool locally when electrical power is unavailable. These electrical and mechanical features maintain reliable switching performance within the hydraulic limits described above.
