4WE6D6X/OFEG24N9K72L AN

The 4WE6D6X/OFEG24N9K72L AN valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation where flow direction must be switched electrically. It uses a D-type spool arranged in two detent positions so the actuator can hold a selected flow path without continuous power, which supports circuit stability during machine cycles. A nominal voltage of 24 V DC and a corresponding rated current of 1.25 A stem from the 30 W nominal power rating, allowing the solenoids to be driven by standard low-voltage control supplies. The electronics accept a ±10 percent voltage variation, preventing nuisance dropouts on mobile equipment. The solenoid system is designed for a 100 percent duty cycle, so the coil can remain energized for long periods without thermal stress. Hydraulic capacity reaches 80 l/min under direct current excitation, letting the valve manage medium-sized actuator flows. Installation aligns with the ANSI B93.9 interface, and the assembly weighs 1.95 kg including two solenoids, which simplifies manifold mounting and handling.

Electrical termination is provided through an M12×1 four-pin K72L connector, giving a sealed plug-in link to the machine wiring harness; the threaded coupling locks firmly in place to resist vibration on mobile platforms. The housing carries an IP65 ingress rating, protecting the coil and connections against dust and low-pressure water jets commonly encountered in industrial wash-down areas. A concealed N9 manual override lets maintenance personnel shift the spool mechanically when power is absent, and this feature is limited to 50 bar tank pressure to avoid seal damage during service. Working ports A, B, and P are rated for 350 bar, while the return port T is specified for 210 bar, enabling the valve to control high-pressure supply lines while discharging to a lower-pressure reservoir. These pressure limits complement the flow capability stated earlier and complete the operating envelope for the series component.
