Finally, we also control the standard of every component and each part of the manufacturing process. A dedicated team of purchasers, engineers, quality inspectors and machine operators works day and night to ensure each component fulfills the stringent Valley quality requirements. Because our suppliers are located in america, we can easily perform random inspections of their services to make sure they are conference our quality requirements. All major irrigation gearbox components are also machined by Valley, providing a second level of quality control. Your final inspection is conducted by examining each gearbox before it really is shipped. And, to further make sure 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 elements. That’s why Valley uses a patented six-barrier input and nine-barrier result seal to keep essential oil in and problems out. To compensate for this longer shaft, unique tires are used that actually move the center of the tire nearer to the gearbox result bearing compared to the industry standard, reducing the load on the gearbox.

Valley also uses U.S.-made, case-hardened bearings created from ultra-pure steel rather than through-hardened Chinese bearings utilized by others. Case-hardening provides superior wear features while maintaining the internal toughness of the primary material. As a result, Valley bearings have a 40 percent higher 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 includes a fully recessed tooth action. With a fully recessed style, the gears keep lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
