The 4WE6J5-6X/EG12N9K40SO43A-1799 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for electrically controlled hydraulic circuits. It operates on a 12 V DC supply and draws 2.5 A during actuation, making it compatible with onboard vehicle power. Connection to the coil is through a Deutsch DT04-2PA plug designated K40. The valve mounts on an NFPA T3.5.1 D03 interface with the ISO 4401-03-02-0-05 port layout, and a clamping length of 42 mm secures it to the subplate. A concealed N9 manual override allows emergency shifting while the tank line is below 50 bar. Reliable performance further depends on hydraulic fluid cleanliness at ISO 4406 code 20/18/15.
Flow capacity reaches 80 l/min, and ports P, A, and B tolerate working pressures up to 350 bar, whereas the tank port is limited to 210 bar under direct current service. Nitrile sealing lets port temperatures rise to 80 °C, and the assembly works in ambient conditions down to −20 °C. Corrosion protection rated for 720 hours of salt spray testing guards the j5 surface finish against harsh environments. The design achieves a mean time to dangerous failure of 300 years as evaluated by EN ISO 13849. These limits define a compact valve suitable for mobile or industrial manifolds that require consistent direction control under demanding pressure, temperature, and environmental loads.
