Finally, we also control the quality of every component and each step in the manufacturing process. A devoted team of purchasers, engineers, quality inspectors and machine operators works day and night to make sure each component satisfies the stringent Valley quality requirements. Because our suppliers are located in america, we can easily perform random inspections of their facilities to make sure they are conference our quality requirements. All major parts are also machined by Valley, providing a second level of quality control. Your final inspection is conducted by tests each gearbox before it is shipped. And, to further make sure Valley quality, randomly selected gearboxes are life-tested in 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 insight and nine-barrier output seal to keep essential oil in and problems out. To compensate for this longer shaft, special wheels are used that actually move the center of the tire closer to the gearbox result bearing than the industry regular, reducing the strain 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 excellent wear features while maintaining the inner toughness of the primary material. As a result, Valley bearings have a 40 irrigation gearbox 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 machine through the field, but, more importantly, the design includes a fully recessed tooth actions. With a completely recessed design, the gears keep lubrication oil between your gears longer, reducing friction for improved load capability and longer life.
