The 4WE6D73-6X/EG24N9K72L/A12/62SO9 valve belongs to the WE Directional Spool Valves series produced by Bosch Rexroth for hydraulic automation tasks that require reliable on-off control of actuator flow. It is built in valve size 6, offering a compact footprint for manifold assemblies. Compatibility with NFPA D03 mounting plates and the ISO 4401-03-02-0-05 porting pattern allows direct replacement in standardized subplates. The unit withstands 350 bar in pressure, A, and B ports, enabling use in high-pressure circuits, while a maximum flow rate of 80 l/min keeps pressure losses low. A clamping length of 42 mm holds the body firmly against the subplate gasket. The wet-pin solenoids operate on 24 V DC and draw 1.25 A during energization, matching common machine power buses.
An M12×1 four-pin connector designated K72L provides quick electrical connection and guided strain relief to the coil leads. A concealed manual override marked N9 lets technicians shift the spool during commissioning or power loss without exposing moving parts. The housing achieves an IP65 rating, protecting internal components from dust ingress and water jets. A locating hole fitted with a locking pin (/62) keeps the valve aligned during bolt tightening and service. The tank port tolerates 210 bar, so the return line can be pressurized when back-pressure functions are needed. Total mass is 1.95 kg with both solenoids installed, easing one-handed installation in tight cabinets. Fluid cleanliness must reach ISO 4406 class 20/18/15 to maintain spool accuracy, and a mean time to dangerous failure of 300 years supports long lifecycles in safety-related hydraulic systems.
