The Z4WE6E53-20/AG24N9Z4S06 directional spool valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth. It routes pressure and return lines in hydraulic automation systems. The nominal size 6 envelope uses porting pattern ISO 4401-03-02-0-05 (D03) to fit standard subplates. Ports P, A, and B are rated for 350 bar, while the T port tolerates 210 bar in direct-current service, ensuring safe discharge of return flow. A maximum flow of 80 l/min supports medium-power cylinders without excessive pressure drop. The solenoid operates on 24 V DC and draws 30 W, supplying constant magnetic force for spool shift. Continuous energization is possible because the coil is specified for a 100 % duty cycle, and stable performance is maintained as long as supply voltage stays within ±10 %.
The valve can be installed in any orientation, so designers can position manifolds vertically or horizontally without affecting function. A concealed manual override permits local actuation during commissioning or electrical failure while guarding against accidental use in normal service. The winding insulation meets class F, which supports reliable operation when the coil surface reaches its 120 °C limit. A permissible switching frequency of 4.2 strokes per second enables rapid circuit response in repetitive tasks. System oil must meet ISO 4406 cleanliness level 20/18/15 to prevent spool sticking and extend service life. The two-solenoid assembly weighs 1.95 kg, keeping manifold sections light enough for single-person handling.
