The 4WE6H73-6X/EG96N9K4/A12V valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation where directional control is required. It operates on a 96 V DC coil supply, and a voltage tolerance of ±10 % keeps the solenoid functional when the supply varies. The coil draws a rated current of 0.33 A, while its 30 W nominal power defines the electrical load that must be provided by the control cabinet. A 100 % ED duty cycle allows the solenoid to stay energized continuously, and insulation class F helps the winding endure elevated temperatures during such service. Wiring uses a DIN EN 175301-803 connector with three pins and protective earth, simplifying replacement in the field. An IP65 protection class keeps dust and water jets from entering the coil housing.
The valve routes pressure up to 350 bar at ports a, b, and p, and it tolerates 210 bar at the tank port, enabling use in high-pressure circuits. A maximum flow of 80 l/min sets the throughput limit for sizing pumps and actuators. The ISO 4401-03-02-0-05 porting pattern matches common subplates, so installation requires no custom machining. Coil surface temperature is limited to 120 °C to protect the winding varnish, and a concealed manual override lets technicians shift the spool when power is unavailable. That override may be used only when the tank line is below 50 bar. FKM seals are fitted to resist hydraulic oil and heat, ensuring leak-free service.
