4WE6J6X/EG24N9DK24L2SO43A-1791

The 4WE6J6X/EG24N9DK24L2SO43A-1791 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation circuits. It meters oil flow between pressure, service, and tank ports, enabling actuators to extend or retract on command. The porting pattern ISO 4401-03-02-0-05 lets the valve bolt directly to size 03 subplates, reducing plumbing complexity. A maximum operating pressure of 350 bar permits use on high-pressure P, A, and B lines, while the tank port may be loaded up to 210 bar to suit systems with elevated return pressures. The valve passes up to 80 l/min, so pump sizing can reach medium-flow applications without excessive pressure drop. A permissible switching frequency of 4.2 cycles per second supports rapid motion sequences common in industrial machines. Continuous energization is possible because the solenoid is rated for a 100 % ED duty cycle, and insulation class F windings withstand internal temperatures associated with such service. The coil surface may reach 120 °C, a limit that guides enclosure ventilation and safety clearances.

Electrical features match modern control cabinets. The coil operates on a nominal 24 V DC supply, drawing 1.25 A and dissipating 30 W during steady state, which simplifies sizing of power supplies and heat management. A voltage tolerance of ±10 % maintains reliable actuation despite line variation. Connection is made through a DK24L plug, an M12 × 1 four-pole interface that supports quick installation and coded wiring. The housing carries an IP65 rating, blocking dust ingress and water jets when the mating connector is fitted. Hydraulic reliability depends on clean media, so the valve requires oil cleanliness of ISO 4406 class 20/18/15 or better to prevent spool wear and sticking. When the coil is de-energized, switch-off transients are limited to 500 V, reducing stress on driver electronics. These parameters together define the valve’s electrical and environmental limits for dependable operation in automated hydraulic manifolds.
