The 4WE6J73-6X/EG12N9K4/A12/62 CSA valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs hydraulic flow to actuators under electrical command in automated machinery. An electromagnetic coil rated at 12 VDC provides actuation; this low control voltage helps when only battery power is available. The coil draws 2.5 A, resulting in a nominal power demand of 30 W that must be supplied by the drive card. A 100 % duty cycle permits continuous energization without forced cooling. Voltage tolerance of ±10 % keeps the device functional during line fluctuations. The maximum coil surface temperature of 120 °C defines the thermal limit for the winding insulation. An IP65 enclosure keeps dust and water jets from entering the solenoid housing.
The valve offers a concealed N9 manual override so maintenance staff can shift the spool mechanically, provided tank pressure does not exceed 50 bar during the procedure. Working ports p, a, and b are rated for 350 bar, while the return port and drain channel withstand up to 210 bar, allowing the unit to survive high-pressure supply yet protect the tank line. A switching frequency of 4.2 operations per second supports rapid cycle tasks in servo-hydraulic loops. Internal passages accommodate 80 l/min of oil, matching medium-flow power units. Mounting is accomplished through the ISO 4401-03-02-0-05 pattern, and the body fits the NFPA T3.5.1 D03 interface for standard subplates. Together these characteristics simplify replacement and shorten installation time in existing hydraulic manifolds.
