The 4WE6D73-6X/OFEG24N9K4/A12 directional spool valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. It shifts hydraulic flow between ports to actuate cylinders or motors in automated machines. The valve bolts to subplates through the ISO 4401-03-02-0-05 mounting interface, allowing straightforward interchange with other CETOP 03 components. A maximum operating pressure of 350 bar on ports P, A, and B accommodates high-pressure supply lines, while 210 bar on port T protects the tank return channel. The design passes up to 80 l/min so medium-size circuits receive adequate volume without cavitation. Continuous service is enabled by a 100 % duty cycle, and the solenoids are energized from a 24 V DC source that draws 1.25 A. The coil accepts a ±10 % voltage swing, and its 30 W power rating helps panel builders size power supplies. A K4 plug conforming to DIN EN 175301-803 provides the electrical interface, and the IP65 rating seals the enclosure against shop dust and wash-down water.
System cleanliness must reach ISO 4406 code 20/18/15 so the spool and bore remain free of abrasive contamination during continuous cycling. The magnetic circuit tolerates a switch-off overvoltage up to 500 V, preventing insulation damage when the driver releases current. With a maximum switching frequency of 4.2 cycles per second, the assembly can follow rapid command changes in positioning fixtures or material-handling valves. Twin wet-armature solenoids and the iron housing weigh 1.95 kg, light enough for manifold mounting without additional supports yet heavy enough to damp hydraulic shock. These performance limits complete the operating profile and ensure predictable response in industrial hydraulic automation.
