The 4WE6E73-6X/EG12N9K4/A12/62 CSA valve directs hydraulic flow in mobile and industrial circuits and belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth. Its porting pattern follows ISO 4401-03-02-0-05, so it mounts on standard size 03 subplates without adapters. The unit withstands 350 bar on ports P, A, and B, while the return port t is limited to 210 bar in direct-current service. Spool passages support a continuous flow of 80 l/min. A 12 V DC solenoid energizes the spool and draws 2.5 A, converting 30 W of electrical power into actuation force. Operation remains stable within a ±10 % voltage band, and the coil can stay energized continuously thanks to a 100 % ED duty rating.
An F-class insulation system protects the winding from heat during extended service. The electrical interface uses a DIN EN 175301-803 form K4 connector that achieves an IP65 seal when coupled. A locating hole with a locking pin, indicated by the /62 suffix, aligns the valve precisely on the manifold. A concealed manual override labeled N9 permits emergency shifting without exposing internal parts. The coil safely quenches up to 500 V of switch-off overvoltage to safeguard upstream electronics. With both solenoids fitted the assembly weighs 1.95 kg, allowing straightforward handling during maintenance.
