The 4WE6D6-6X/EG24N9DK24L/62SO43A-1170 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. The unit directs hydraulic flow in automated circuits by shifting a nominal size 6 spool between discrete positions. It bolts to manifolds through the ISO 4401-03-02-0-05 interface, while a matching NFPA T3.5.1 R2-2002 D03 pattern offers compatibility with American subplates. During service the valve carries system pressure up to 350 bar and sustains up to 210 bar on the tank port, making it suitable for medium-pressure actuators. A maximum direct-current flow of 80 l/min passes through the galleries without exceeding rated losses, supporting rapid cylinder or motor movement. The solenoid is energized with a 24 V DC supply, and operation remains stable even when line voltage drifts within ±10 percent. These hydraulic and electrical limits define the valve’s role in precise motion-control loops.
The electromagnetic assembly employs a standard 30 W coil that draws 1.25 A at the nominal voltage to shift the spool without delay. Class F insulation protects the winding from heat generated during continuous duty, while the 100 percent ED rating confirms that the coil may remain energized indefinitely in cyclic machines. A concealed manual override permits local actuation when commissioning or troubleshooting without exposing the mechanism to contaminants. Electrical connection is made through an M12×1 four-pole plug, simplifying quick replacement in modular manifolds and maintaining the IP65 enclosure rating against dust and low-pressure water. Surge suppression inside the housing keeps switch-off overvoltage below 500 V, preventing premature contact wear in the control circuitry. Together these design points ensure reliable solenoid shifting and long service life in hydraulic automation tasks.
