The 4WE6J6X/EW24N9DA/H15 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series for hydraulic automation. A high-power wet-pin solenoid with a detachable coil shifts the J-type spool and is energized by a 24 V DC supply that draws 1.25 A, amounting to 30 W of electrical load. Supply variation of up to ±10 percent is accepted, and continuous energization is permitted by the 100 percent S1 duty rating. The coil uses insulation class F materials, and its surface temperature may rise to 120 °C under peak thermal conditions. A concealed manual override coded N9 enables local actuation during commissioning or power loss.
The valve mounts to manifolds that follow the ISO 4401-03-02-0-05 interface and matches NFPA port size D03, facilitating direct replacement in existing stacks. Ports p, a, and b tolerate operating pressures of 350 bar, while the tank port t is rated for 210 bar to ensure safe return flow. The flow path handles up to 80 l/min, and a 1.5 mm throttle insert in port A (option H15) tempers actuator speed without external orifices. These ratings suit compact hydraulic circuits needing high flow, controlled deceleration, and reliable direction control while allowing technicians to service the electrical section without disturbing pressurized connections.
