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 night and day to ensure each component meets the stringent Valley quality requirements. Because our suppliers are located in america, we can simply perform random inspections of their services to make sure they are conference our quality requirements. All major parts are also machined by Valley, providing another quality level control. A final inspection is performed by assessment 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 best gear style and components 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 essential oil in and problems out. To compensate for this longer shaft, unique tires are used that truly move the center of the tire closer to the gearbox output bearing compared to the irrigation gearbox industry standard, reducing the load on the gearbox.

Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel instead of through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear characteristics while maintaining the inner toughness of the primary material. As a result, Valley bearings possess a 40 percent higher load rating.

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