Finally, we also control the quality of every component and each step in the manufacturing process. A devoted team of customers, engineers, quality inspectors and machine operators works night and day to make sure each component fulfills the stringent irrigation gearbox Valley quality requirements. Because our suppliers are positioned in america, we can easily perform random inspections of their services to ensure they are meeting our quality standards. All major parts are also machined by Valley, providing another quality level control. A final inspection is performed by screening each gearbox before it really is shipped. And, to further make certain Valley quality, randomly selected 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 components. That’s why Valley uses a 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 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 superior wear characteristics while maintaining the internal toughness of the core material. As a result, 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 much less energy to move the device through the field, but, moreover, the design has a fully recessed tooth action. With a fully recessed style, the gears maintain lubrication oil between your gears longer, reducing friction for improved load capacity and longer life.
