Finally, we also control the quality of each component and each part of the manufacturing process. A dedicated team of buyers, engineers, quality inspectors and machine operators works night and day to make sure each component satisfies the stringent irrigation gearbox Valley quality requirements. Because our suppliers are located in america, we can simply perform random inspections of their services 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 examining each gearbox before it is shipped. And, to further ensure Valley quality, randomly chosen 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 uses a patented six-barrier insight and nine-barrier output seal to keep essential oil in and complications out. To compensate for this longer shaft, special tires are used that truly move the guts of the tire nearer to the gearbox output 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 superior wear features while maintaining the inner toughness of the core material. As a result, Valley bearings have a 40 percent better load rating.

The Valley gearbox also has a 52:1 gear ratio. This implies the gearbox uses 4 percent less energy to move the device through the field, but, more importantly, the design has a completely recessed tooth action. With a completely recessed style, the gears maintain lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
