Finally, we also control the standard of every component and each part of the manufacturing process. A devoted team of customers, engineers, quality inspectors and machine operators works day and night to ensure each component fulfills the stringent Valley quality requirements. Because our suppliers are positioned in america, we can certainly perform random inspections of their facilities to ensure they are conference our quality criteria. All major parts are also machined by Valley, providing another level of quality control. A final inspection is performed by assessment each gearbox before it really is shipped. And, to help expand guarantee Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.
But, even the very best gear design 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 essential oil in and problems out. To compensate because of this longer shaft, particular tires are used that actually move the center of the tire nearer to the gearbox result bearing than the industry regular, reducing the load on the gearbox.
Valley also uses U.S.-made, case-hardened bearings made from irrigation gearbox ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear characteristics while maintaining the internal 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 implies the gearbox uses 4 percent less energy to move the machine through the field, but, more importantly, the design includes a fully recessed tooth action. With a fully recessed style, the gears keep lubrication oil between the gears longer, reducing friction for increased load capability and longer life.
