4WE6J73-6X/EG96N9K4

The 4WE6J73-6X/EG96N9K4 directional valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated circuits for machine tools and industrial equipment. The solenoid assembly is rated for a coil voltage of 96 VDC so the valve can be driven from a dedicated low-voltage power supply. A steady rated current of 0.33 A allows precise actuation without overloading control relays, while the nominal power requirement is limited to 30 W to keep panel power budgets low. Continuous operation is supported by a 100 percent duty cycle, meaning the coil may remain energized indefinitely during extended machine cycles. The electronics tolerate ±10 percent supply variation, which shields performance from minor line fluctuations. Electrical hookup is completed through a DIN EN 175301-803 three-pin connector, selected for quick replacement and clear pin identification. A concealed manual override is provided so technicians can shift the spool during commissioning; the override is specified for tank pressures up to 50 bar to prevent damage when circuits are pressurized. An IP65 enclosure rating blocks dust and water jets, making the valve suitable for wash-down installations in hydraulic power units.

In service, the valve conducts up to 80 l/min of hydraulic oil in direct current operation, giving it capacity for medium-size cylinders and motors. The pressure ports A, B, and P withstand 350 bar, permitting use in high-pressure systems, while the tank port T is limited to 210 bar to protect return-line components. The magnetic circuit can switch the spool at a maximum frequency of 4.2 cycles per second, enabling closed-loop controls that demand rapid directional changes. Mechanical interface follows the NFPA D03 mounting pattern so the unit bolts directly to common subplates, and the porting layout complies with ISO 4401-03-02-0-05 to maintain interchangeability with other manufacturers. With two solenoids installed, the assembly weighs 1.95 kg, light enough for manifold blocks supported only by piping. These dimensional and performance parameters make the 4WE6J73-6X/EG96N9K4 a consistent choice for hydraulic automation tasks that call for repeatable flow direction under variable load conditions.
