The 4WE6J73-6X/EG96N9K4/A12B25 valve belongs to the WE Directional Spool Valves series from Bosch Rexroth and directs hydraulic flow to actuators in automated machinery. Its nominal size 6 keeps the envelope small while still passing oil efficiently, and the J73 spool configuration establishes the flow paths needed for bidirectional cylinder control. A maximum operating pressure of 350 bar allows use in high-pressure circuits, and continuous flow capacity reaches 80 l/min so medium-duty drives are not starved. The solenoid is wound for 96 V DC and draws 0.33 A, giving control cabinets a clear power requirement. Connection is through a K4 plug that follows DIN EN 175301-803, which simplifies coil replacement and field wiring. Once installed, the housing and plug achieve IP65 protection, keeping dust and water jets away from the coil and spool chamber.
The body mounts to subplates that use the ISO 4401-03-02-0-05 porting pattern, and it also matches the NFPA T3.5.1 R2-2002 D03 footprint for equipment built to North American standards. A B25 throttle insert with a 2.5 mm orifice is fitted in the P port to limit inrush flow and damp pressure peaks. Code A12 increases switching time, producing a smoother spool transition when rapid reversal would disturb the system. For de-energized operation, a concealed N9 manual override lets technicians shift the spool; the override is rated for return-line pressures up to 50 bar so backpressure will not force the knob out. Coil insulation meets category I under VDE 0580, confirming the winding’s electrical safety. These details allow the valve to provide dependable, adjustable flow direction in hydraulic automation.
