The 4WE6E6X/EG12N9K40SO43A-1799 valve is produced by Bosch Rexroth for the WE Directional Spool Valves series and is intended to route fluid in automated hydraulic circuits. The solenoid is rated for a 12 V DC supply and draws 2.5 A, enabling direct connection to mobile electrical systems. Continuous energization is supported by a 100 % ED (S1) duty rating, while a 30 W power demand limits battery drain. Thermal stability is maintained up to a coil temperature of 120 °C. Connection is made with a DT04-2PA Deutsch 2-pin plug that resists vibration. An IP69K housing shields the enclosure from high-pressure washdown, and the build meets Protection Class III under VDE 0580 for reinforced insulation. These electrical features are packaged in a size 6 body suited for compact manifolds.


Hydraulic performance begins with the ISO 4401-03-02-0-05 mounting pattern, which fits standard NG6 sub-plates without adapters. Four working ports let the spool direct pressure, return, and two actuator lines for bidirectional motion. The flow path handles up to 80 l/min in direct-current operation, and the P, A, and B passages safely withstand 350 bar, while the T port is limited to 210 bar. Spool shifts can be commanded at rates up to 4.2 cycles per second, allowing responsive control in mobile or industrial machinery. These limits refine flow, pressure, and switching speed to provide reliable directional control in hydraulic automation.
