The 4WE6JA6X/EG24N9DK24L directional spool valve is produced by Bosch Rexroth for the WE Directional Spool Valves series, where it directs pressure and return lines in compact hydraulic manifolds. With a nominal size of 6, also referenced as NG6, the unit fits into systems using the ISO 4401-03-02-0-05 porting pattern and attaches to subplates through the NFPA D03 mounting interface, ensuring interchangeability with standard blocks. Electrical power is delivered through an M12×1 four-pole DK24L connector, and the coil operates from a 24 V DC supply drawing a rated current of 1.25 A. A nominal power rating of 30 W keeps temperature rise within limits while the 100 % duty cycle permits continuous solenoid activation in automated cycles. Protection class IP65 shields the housing against dust ingress and low-pressure water jets, allowing dependable performance in exposed plant locations.
For flow control, the valve passes up to 80 l/min under direct-current actuation, and it tolerates system pressures as high as 350 bar on the pressure port while the tank port may be loaded to 210 bar without damage. Switching events can occur at a maximum frequency of 4.2 operations per second, giving rapid response in positioning circuits, and the coil insulation withstands switch-off overvoltages up to 500 V to prevent breakdown when the magnetic field collapses. Hydraulic oil supplied to the unit must meet cleanliness class ISO 4406 20/18/15 so the narrow spool clearances remain free of abrasive particles and maintain low leakage. Together these parameters confirm suitability for high-cycle hydraulic automation where compact size, fast shifting, and robust pressure capability are required.
