Finally, we also 
control the standard of each component and each part of the manufacturing 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 situated in america, we can certainly perform random inspections of their facilities to make sure they are meeting our quality requirements. All major components are also machined by Valley, providing a second quality level control. Your final inspection is performed by screening each irrigation gearbox gearbox before it is shipped. And, to help expand guarantee Valley quality, randomly selected 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 runs on the patented six-barrier input and nine-barrier output seal to keep essential oil in and problems out. To compensate because of this longer shaft, unique wheels are used that truly move the guts of the tire closer to the gearbox result bearing than the industry regular, reducing the strain on the gearbox.
Valley also uses U.S.-made, case-hardened bearings made from ultra-pure steel rather than through-hardened Chinese bearings used by others. Case-hardening provides superior wear features 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 offers a 52:1 gear ratio. This implies the gearbox uses 4 percent much 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 keep lubrication oil between your gears longer, reducing friction for increased load capacity and longer life.
