4WE6J73-6X/EG24N9K4/A12/62S043A-1799

The 4WE6J73-6X/EG24N9K4/A12/62S043A-1799 directional spool valve belongs to the WE Directional Spool Valves series manufactured by Bosch Rexroth for hydraulic automation where directional control of pressurized oil is required. Its nominal size of 6 defines the mounting envelope so the unit fits compact ISO subplates, and the ISO 4401-03-02-0-05 porting pattern aligns each pressure and return passage without adapters. A maximum operating pressure of 350 bar at ports a, b, and p lets the valve handle high-pressure supply lines, while the tank port tolerates 210 bar in DC service to protect return plumbing. The design accommodates up to 80 l/min of flow, supporting medium-capacity cylinders and motors. Electrical actuation relies on a 24 V DC coil whose voltage tolerance of ±10 percent maintains consistent shifting even with modest bus variation. A rated current of 1.25 A pairs with the 30 W nominal power figure to specify the control load presented to machine power supplies. The solenoid is rated for a 100 percent S1 duty cycle so it can remain energized continuously without thermal derating.

The valve connects electrically through a DIN EN 175301-803 three-pole plug with a protective earth contact, simplifying wiring and grounding in control cabinets. A concealed manual override is integrated for emergency actuation yet remains shielded to avoid inadvertent operation during routine maintenance. The enclosure achieves an IP65 protection class, which blocks dust ingress and withstands low-pressure water jets so the assembly endures washdown zones or outdoor equipment frames. Coil surface temperature is limited to 120 °C, establishing the thermal boundary that guides ambient temperature selection and cooling airflow inside the manifold block. Overall weight of 1.95 kg allows straightforward handling when installing stacks or replacing individual sections without lifting fixtures.
