The 4WE6D6X/OFEG24K4 directional spool valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It routes pressurized oil among actuator, pump, and tank lines in hydraulic automation systems. The valve is built in nominal size 6 so it fits standard CETOP 03 manifolds, and its porting pattern follows ISO 4401-03-02-0-05 for straightforward subplate mounting. Actuation is provided by a wet-pin high-power solenoid that operates on 24 V DC, while a nominal coil power of 30 W delivers the force needed to shift the spool under load. The coil is rated for a continuous duty cycle of 100 % ED which allows indefinite energization without overheating. An IP65 protection class shields the enclosure against dust and water spray when the connector is correctly installed, and the complete assembly with two solenoids weighs 1.95 kg which supports easy handling during installation.
Hydraulic performance is defined by a maximum operating pressure of 350 bar on ports A, B, and P, and a maximum tank port pressure of 210 bar on port T when used in direct current service. The valve passes up to 80 l/min at the rated pressure drop, and the spool can be shifted up to 4.2 times per second to suit fast cycling machines. Fluid cleanliness must meet ISO 4406 class 20/18/15 to prevent premature wear. A detent is included so the spool remains in its last commanded position after power is removed, and no manual override is provided, eliminating the risk of unauthorized hand actuation. Electrical connection is made through a DIN EN 175301-803 plug with three pins and a protective earth conductor which simplifies service replacement.
