Finally, we also control the standard of every component and each step in the manufacturing irrigation gearbox process. A dedicated team of customers, engineers, quality inspectors and machine operators works night and day to make sure each component fulfills the stringent Valley quality requirements. Because our suppliers are positioned in the United States, we can simply perform random inspections of 
their services to make sure they are conference our quality specifications. All major elements are also machined by Valley, providing a second quality level control. Your final inspection is conducted by testing each gearbox before it is shipped. And, to help expand make certain Valley quality, randomly selected gearboxes are life-tested in our gearbox testing laboratory.
But, even the best gear style and components won’t help if the gearbox isn’t sealed from the components. That’s why Valley runs on the patented six-barrier insight and nine-barrier result seal to keep oil in and complications out. To compensate for this longer shaft, special tires are used that truly move the center of the tire nearer to the gearbox result bearing compared to 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 superior wear features while maintaining the inner toughness of the core material. Consequently, Valley bearings possess a 40 percent better load rating.
The Valley gearbox also has 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 completely recessed tooth actions. With a completely recessed style, the gears maintain lubrication oil between your gears longer, reducing friction for improved load capability and longer life.
