Finally, we also control the irrigation gearbox quality of each component and each part of the manufacturing process. A dedicated team of purchasers, engineers, quality inspectors and machine operators works day and night to ensure each component satisfies the stringent Valley quality requirements. Because our suppliers are positioned in america, we can simply perform random inspections of their services to make sure they are meeting our quality specifications. All major components are also machined by Valley, providing a second level of quality control. A final inspection is performed by assessment each gearbox before it is shipped. And, to further make sure Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.
But, even the 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 result seal to keep essential oil in and complications out. To compensate for this longer shaft, particular wheels are used that actually move the guts of the tire nearer to the gearbox output bearing compared to the industry standard, reducing the strain on the gearbox.
Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear features while maintaining the inner toughness of the primary material. Because of this, Valley bearings possess a 40 percent greater load rating.
The Valley gearbox also offers a 52:1 gear ratio. This means the gearbox uses 4 percent less energy to move the device through the field, but, moreover, the design has a completely recessed tooth actions. With a completely recessed style, the gears maintain lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
