Finally, we also control the standard of each component and each step in the manufacturing process. A devoted team of customers, engineers, quality inspectors and machine operators works night and day to ensure each component meets the stringent Valley quality requirements. Because our suppliers are located in america, we can easily perform random inspections of their facilities to make sure they are meeting our quality standards. All major elements are also machined by Valley, providing a second quality level control. Your final inspection is conducted by assessment each gearbox before it is shipped. And, to further guarantee Valley quality, randomly selected gearboxes are life-tested in our gearbox testing irrigation gearbox laboratory.
But, even the very best gear design 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 oil in and complications out. To compensate for this longer shaft, particular wheels are used that truly move the guts of the tire nearer to the gearbox result bearing than the industry regular, reducing the strain on the gearbox.
Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel instead of through-hardened Chinese bearings utilized by others. Case-hardening provides excellent wear characteristics while maintaining the internal toughness of the core material. Because of this, Valley bearings possess a 40 percent higher 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 includes a fully recessed tooth actions. 
With a fully recessed design, the gears maintain lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
