Finally, we also control the quality of each component and each part of the manufacturing process. A devoted team of purchasers, engineers, quality inspectors and machine operators works day and night to ensure each component meets the stringent Valley quality requirements. Because our suppliers are located in the United States, we can certainly perform random inspections of their facilities to ensure they are conference our quality standards. All major components are also machined by Valley, providing a second level of quality control. A final inspection is performed by tests each gearbox before it is shipped. And, to help expand assure Valley quality, randomly selected gearboxes are life-tested in our gearbox testing laboratory.

But, even the 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 complications out. To compensate because of this irrigation gearbox longer shaft, special tires are used that truly move the guts of the tire closer to the gearbox result bearing compared to the industry regular, reducing the strain on the gearbox.

Valley also uses U.S.-made, case-hardened bearings made from ultra-pure steel instead of through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear features while maintaining the internal toughness of the primary material. Because of this, Valley bearings possess a 40 percent greater 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, moreover, the design includes a completely recessed tooth action. With a completely recessed style, the gears maintain lubrication oil between the gears longer, reducing friction for increased load capacity and longer life.
