Finally, we also control the quality of each component and each step in the manufacturing process. A dedicated team of buyers, engineers, quality inspectors and machine operators works night and day to ensure each component fulfills the irrigation gearbox stringent Valley quality requirements. Because our suppliers are located in america, we can easily perform random inspections of their facilities to ensure they are meeting our quality specifications. All major components are also machined by Valley, providing another level of quality control. A final inspection is performed by tests each gearbox before it is shipped. And, to further guarantee Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.

But, even the best gear style and materials won’t help if the gearbox isn’t sealed from the elements. That’s why Valley runs on the patented six-barrier insight and nine-barrier output seal to keep oil in and problems out. To compensate for this longer shaft, unique tires are used that truly move the center of the tire closer to the gearbox output bearing than the industry standard, reducing the strain on the gearbox.

Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides excellent wear characteristics while maintaining the inner toughness of the primary material. Because of this, Valley bearings possess a 40 percent greater load rating.

The Valley gearbox also offers a 52:1 gear ratio. This means the gearbox uses 4 percent much less energy to move the device through the field, but, moreover, the design has a completely recessed tooth action. With a completely recessed design, the gears keep lubrication oil between the gears longer, reducing friction for increased load capability and longer life.
