4WE6J73-6X/EG24N9DK24L2/62

The 4WE6J73-6X/EG24N9DK24L2/62 directional spool valve is manufactured by Bosch Rexroth for the WE Directional Spool Valves series. It directs hydraulic flow in automated machinery that requires reliable on-off control. The unit is built to nominal size 6, fitting compact valve stacks where space is limited. A NFPA D03 mounting interface enables direct attachment to common subplates. The porting arrangement matches ISO 4401-03-02-0-05 so manifold ports line up without modification. Electrical power is supplied through a central M12x1 four-pin connector rated for control wiring in industrial environments. The coil operates at 24 V DC, accepts a ±10 % voltage window, and draws 30 W during steady energization. Because the solenoid is specified for a 100 % ED duty cycle and housed in an IP65 enclosure, it can remain energized continuously without risk from dust or water. Total mass is 1.95 kg, allowing manual installation without lifting aids.

In service the valve withstands a maximum operating pressure of 350 bar on pressure ports. It passes up to 80 L/min of hydraulic fluid under direct current actuation, covering the flow range of medium-sized actuators. The tank port may see back-pressures as high as 210 bar in DC circuits without compromising function. A switching rate of 4.2 cycles per second supports control loops that do not demand extreme dynamics yet need repeatable positioning. Approved media include HL, HLP, HLPD, HVLP, and HVLPD oils, letting designers match viscosity and additive packages to system needs. Accurate alignment on the manifold is secured by a locating hole drilled for an ISO 8752-3×8 spring pin. These mechanical tolerances control spool guidance and reduce edge loading under peak differential pressure. Combined with the permitted switching frequency, they ensure seat wear remains within limits across continuous cycles. Engineers can rely on these values when sizing relief valves and accumulators in the same circuit.
