The 4WE6J73-6X/EG24N9DAL/A12/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic oil to cylinders and motors in automated equipment and fits size 6 (NG6) cavities so manifolds stay compact. The mounting interface follows the NFPA D03 pattern, permitting direct attachment to widely used subplates. A porting layout of ISO 4401-03-02-0-05 aligns the pressure and work ports with international manifold standards. The valve tolerates a maximum operating pressure of 350 bar at the pressure, A, and B ports, allowing high force outputs. Tank port t can accept up to 210 bar, letting designers run systems with controlled back-pressure. A maximum flow of 80 l/min moves sufficient fluid for medium power actuators without excessive loss. Switching capability reaches 4.2 cycles per second, supporting fast reversal in indexing or clamping circuits.
The solenoid is rated for 24 V DC, enabling direct connection to common control supplies, and it draws 1.25 A under this voltage to simplify fuse sizing. Electrical demand is limited to 30 W, which helps manage cabinet heat. A 100% ED duty cycle allows the coil to remain energized continuously during long process runs. Even under continuous duty, the coil surface temperature does not exceed 120 °C, protecting insulation and nearby wiring. The enclosure achieves IP65, guarding the internals from dust and low-pressure washdown. Wiring enters through a DAL 1/2-14 NPT cable gland, providing a secure threaded seal for conduit. A concealed N9 manual override lets technicians shift the spool during setup without exposing moving parts in operation. Positioning accuracy is maintained by a locating pin included with the /62 option, preventing rotation during installation.
