Finally, we also control the standard of each component and each step in the manufacturing process. A devoted team of customers, engineers, irrigation gearbox quality inspectors and machine operators works night and day to ensure each component satisfies the stringent Valley quality requirements. Because our suppliers are situated in the United States, we can certainly perform random inspections of their services to make sure they are conference our quality specifications. All major components are also machined by Valley, providing another quality level control. Your final inspection is performed by testing each gearbox before it is shipped. And, to help expand make sure Valley quality, randomly selected gearboxes are life-tested in our gearbox testing laboratory.

But, even the very best gear style 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 output seal to keep essential oil in and problems out. To compensate for this longer shaft, particular tires are used that actually move the guts of the tire nearer to the gearbox result bearing than the industry regular, reducing the strain on the gearbox.

Valley also uses U.S.-made, case-hardened bearings made from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides excellent wear features while maintaining the internal toughness of the primary material. As a result, Valley bearings have a 40 percent greater load rating.

The Valley gearbox also offers 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 completely recessed tooth actions. With a completely recessed style, the gears keep lubrication oil between the gears longer, reducing friction for improved load capability and longer life.
