Finally, we also control the quality of every 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 satisfies the stringent Valley quality requirements. Because our suppliers are positioned in america, we can simply perform random inspections of their facilities to ensure they are conference our quality standards. All major components are also machined by Valley, providing another level of quality control. Your final inspection is performed by screening each gearbox before it really is shipped. And, to help expand assure Valley quality, randomly selected gearboxes are life-tested inside our gearbox testing laboratory.
But, even the best gear design and components won’t help if the gearbox isn’t sealed from the components. That’s why Valley uses a patented six-barrier insight and nine-barrier result seal to keep essential oil in and problems out. To compensate for this longer shaft, irrigation gearbox special wheels are used that truly move the guts of the tire nearer to the gearbox output bearing than the industry standard, 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 used by others. Case-hardening provides excellent wear features while maintaining the internal toughness of the core material. Because of this, 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 much less energy to move the device through the field, but, more importantly, the design has a fully recessed tooth actions. With a completely recessed style, the gears maintain lubrication oil between the gears longer, reducing friction for increased load capacity and longer life.
