Finally, we also control the standard of each component and each part of the manufacturing process. A devoted team of customers, engineers, quality inspectors and machine operators works night and day to make sure each component satisfies the stringent Valley quality requirements. Because our suppliers are situated in america, we can easily perform random inspections of their services to make sure they are conference our quality criteria. All major elements are also machined by Valley, providing another level of quality control. Your final inspection is performed by testing each gearbox before it is shipped. And, to help expand ensure Valley quality, randomly selected gearboxes are life-tested inside our gearbox testing laboratory.
But, even the very best gear style and materials won’t help if the gearbox isn’t sealed from the elements. That’s why Valley runs on the patented six-barrier insight and nine-barrier result seal to keep oil in and problems out. To compensate because of this irrigation gearbox longer shaft, particular 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 created from ultra-pure steel instead of through-hardened Chinese bearings 
utilized by others. Case-hardening provides excellent wear characteristics while maintaining the inner toughness of the core material. Consequently, Valley bearings possess a 40 percent greater load rating.
The Valley gearbox also has a 52:1 gear ratio. This means the gearbox uses 4 percent less energy to move the machine through the field, but, moreover, the design has a fully recessed tooth action. With a completely recessed style, the gears keep lubrication oil between your gears longer, reducing friction for improved load capability and longer life.
