Finally, we also control the standard of every component and each part of the manufacturing process. A dedicated team of purchasers, engineers, quality inspectors and machine irrigation gearbox operators works night and day to ensure each component fulfills the stringent Valley quality requirements. Because our suppliers are situated in the United States, we can certainly perform random inspections of their facilities to ensure they are meeting our quality standards. All major elements are also machined by Valley, providing another quality level control. A final inspection is conducted by assessment each gearbox before it really is shipped. And, to further ensure Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.

But, even the very best gear style and materials won’t help if the gearbox isn’t sealed from the components. That’s why Valley uses a patented six-barrier insight and nine-barrier output seal to keep oil in and problems out. To compensate for this longer shaft, particular wheels are used that actually move the center of the tire closer to the gearbox result bearing compared to the industry standard, reducing the load on the gearbox.

Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel instead of through-hardened Chinese bearings used by others. Case-hardening provides excellent wear features while maintaining the internal 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 implies the gearbox uses 4 percent less energy to move the machine through the field, but, moreover, the design has a fully recessed tooth actions. With a fully recessed style, the gears keep lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
