The 4WE6D73-6X/OFEG24N9K72L/A12 directional spool valve belongs to the WE Directional Spool Valves series and is produced by Bosch Rexroth for hydraulic automation circuits that require reliable flow switching. It bolts to subplates that follow the ISO 4401-03-02-0-05 porting pattern and withstands 350 bar at ports A, B, and P while allowing a direct-current flow rate of 80 l/min. A detent spool holds its position without a return spring, and a concealed N9 manual override lets technicians shift the element when the circuit is de-energized. The solenoid operates continuously at 100 % duty on a 24 V DC supply, drawing 1.25 A within a ±10 % voltage window.
The coil consumes 30 W and uses insulation class F wire, permitting a surface temperature up to 120 °C during prolonged service. Electrical connection is made with a four-pole M12×1 plug coded K72L, a configuration that supports a maximum switching frequency of 1 Hz under direct current. An IP65 housing protects the assembly against dust ingress and low-pressure water jets, and the tank port tolerates 210 bar so the unit can run in high-backpressure return lines. Together, these characteristics suit mobile or stationary installations that need dependable thermal behavior, controlled actuation rates, and sealed electrical linkage.
