Finally, we also control the standard of every component and each part of the manufacturing process. A devoted team of buyers, engineers, quality inspectors and machine operators works night and day to ensure each component meets the stringent irrigation gearbox Valley quality requirements. Because our suppliers are located in america, we can easily perform random inspections of their facilities to make sure they are meeting our quality requirements. All major elements are also machined by Valley, providing another quality level control. A final inspection is conducted by tests each gearbox before it really is shipped. And, to help expand guarantee Valley quality, randomly chosen gearboxes are life-tested inside our gearbox testing laboratory.

But, even the very best gear design and components 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 essential oil in and problems out. To compensate for this longer shaft, unique wheels are used that actually move the center of the tire nearer to the gearbox result bearing compared to the industry regular, reducing the load 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 excellent wear features while maintaining the inner toughness of the core material. As a result, 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 less energy to move the machine through the field, but, moreover, the design has a completely recessed tooth action. With a completely recessed design, the gears keep lubrication oil between the gears longer, reducing friction for improved load capacity and longer life.
