4WE6G6X/EG12N9K4/62SO43A-1661

The 4WE6G6X/EG12N9K4/62SO43A-1661 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It routes pressurized fluid to selected actuator ports in hydraulic automation systems. The valve is built to the nominal size 6 format so it can be installed on NG6 manifolds without adapters. A mounting interface conforming to NFPA T3.5.1 D03 allows direct bolt-down on standard subplates. The ISO 4401-03-02-0-05 porting pattern keeps passage alignment consistent with other NG6 components. Flow capacity reaches 80 liters per minute under direct-current operation, enabling medium-flow circuits to operate without excessive pressure loss. Continuous line pressure up to 350 bar is permissible on the P, A, and B ports, while the T port withstands 210 bar in DC service, ensuring safe return-line operation. A duty cycle of 100 percent ED lets the solenoid remain energized continuously, and an IP65 enclosure rating protects the coil against dust and low-pressure water during machine wash-downs.

The solenoid section operates on 12 V DC and draws 30 W, providing the magnetic force required to shift the spool with consistent response. A voltage tolerance of ±10 percent keeps the coil within safe limits when supply levels fluctuate. The electrical connection follows the DIN EN 175301-803 form K4 standard, enabling quick plug-in wiring with molded connectors. The maximum coil surface temperature is limited to 120 °C, so thermal overload is avoided during prolonged energization. Switch-off transients are limited by an allowable overvoltage of 500 V, preventing insulation damage when the field collapses. The design handles switching frequencies up to 4.2 cycles per second in direct-current service, supporting rapid machine sequences. These electrical limits, combined with the hydraulic capabilities outlined earlier, allow the valve to perform precise directional control in automated presses, molding machines, and similar equipment.
