Finally, we also control the standard of every component and each step in the manufacturing process. A dedicated team of purchasers, engineers, quality inspectors and machine operators works day and night to make sure each component meets the stringent Valley quality requirements. Because our suppliers are positioned in america, we can easily perform random inspections of their facilities to ensure they are conference our quality specifications. All major elements are also machined by Valley, providing another quality level control. Your final inspection is performed by tests each gearbox before it is irrigation gearbox shipped. And, to help expand make sure Valley quality, randomly chosen gearboxes are life-tested inside 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 uses a patented six-barrier insight and nine-barrier result seal to keep oil in and complications out. To compensate for this longer shaft, particular tires are used that actually move the center of the tire nearer to the gearbox output bearing compared to the industry standard, 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 characteristics while maintaining the internal toughness of the primary material. Because of this, Valley bearings possess a 40 percent higher load rating.

The Valley gearbox also offers a 52:1 gear ratio. This implies the gearbox uses 4 percent much less energy to move the machine through the field, but, moreover, the design has a fully recessed tooth actions. With a fully recessed design, the gears maintain lubrication oil between the gears longer, reducing friction for improved load capacity and longer life.
