4WE6H73A6X/EG24N9K72L/A12 AN

The 4WE6H73A6X/EG24N9K72L/A12 AN directional spool valve belongs to the WE Directional Spool Valves series and is manufactured by Bosch Rexroth for hydraulic automation circuits that require reliable flow direction control. Its size 6 (NG6) body fits standardized subplates, while the ANSI B93.9 porting pattern aligns the work ports for quick manifold integration. A nominal voltage of 24 V DC powers the solenoids, and the coil draws 1.25 A under that supply, so power distribution panels can be sized accurately. The ±10 % voltage tolerance keeps actuation consistent when supply levels fluctuate. With a nominal power rating of 30 W, the coil generates limited heat during continuous service, which is supported by a 100 % duty cycle for uninterrupted operation. Hydraulic performance reaches up to 80 l/min, and the P, A, B ports withstand 350 bar, allowing the valve to handle high-pressure actuator lines. Electrical hookup is completed through an M12 x 1 four-pole connector (K72L) that streamlines cable routing in compact machines.

The fluid cleanliness requirement of ISO 4406 20/18/15 protects the metering edges from accelerated wear, so filtration systems must keep particle counts within that range. A housing protection rating of IP65 prevents dust ingress and water jets from affecting the coil enclosure, making the valve suitable for open machine frames. The maximum coil surface temperature of 120 °C defines the thermal limit for ambient and fluid conditions to prevent insulation damage. Tank and drain ports may be subjected to 210 bar, a figure that guides reservoir and return-line component selection. During rapid sequencing, the solenoid can shift the spool up to 4.2 times per second, supporting moderate cycling tasks without overstressing the mechanism. The assembly weighs 1.95 kg in its two-solenoid configuration, so mounting brackets must accommodate that mass while minimizing vibration. These parameters collectively ensure predictable switching, adequate environmental protection, and long service life in automated hydraulic machinery.
