Finally, we also control the standard of every component and each part of the manufacturing process. A dedicated team of buyers, engineers, quality inspectors and machine operators works night and day to ensure each component meets the stringent Valley quality requirements. Because our suppliers are positioned in the United States, we can certainly perform random inspections of their facilities to make sure they are conference our quality specifications. All major parts are also machined by Valley, providing a second quality level control. Your final inspection is performed by examining each gearbox before it is shipped. And, to further ensure Valley quality, randomly selected gearboxes are life-tested inside our gearbox testing laboratory.

But, even the best gear style and components won’t help if the gearbox isn’t sealed from the elements. That’s why Valley runs on the patented six-barrier input and nine-barrier output seal to keep essential oil in and problems out. To compensate for this longer shaft, particular wheels are used that actually move the guts of the tire nearer to the gearbox output 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 rather than through-hardened Chinese bearings used by others. Case-hardening provides excellent wear features while maintaining the inner toughness of the primary material. Because of this, Valley bearings possess a 40 irrigation gearbox percent greater load rating.

The Valley gearbox also offers a 52:1 gear ratio. This implies the gearbox uses 4 percent much less energy to move the machine through the field, but, more importantly, the design has a fully recessed tooth action. With a fully recessed style, the gears keep lubrication oil between your gears longer, reducing friction for improved load capability and longer life.
