Finally, we also control the standard of each component and each step in the manufacturing process. A devoted team of customers, engineers, quality irrigation gearbox inspectors and machine operators works night and day to make sure each component meets the stringent Valley quality requirements. Because our suppliers are situated in america, we can easily perform random inspections of their services to ensure they are conference our quality criteria. All major components are also machined by Valley, providing another quality level control. Your final inspection is performed by testing each gearbox before it really is shipped. And, to further guarantee Valley quality, randomly chosen gearboxes are life-tested in our gearbox testing laboratory.

But, even the very best gear style and materials 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 complications out. To compensate for this longer shaft, special wheels are used that truly move the center of the tire closer to the gearbox output bearing compared to the industry standard, 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 utilized by others. Case-hardening provides superior wear characteristics while maintaining the internal toughness of the primary material. As a result, Valley bearings have a 40 percent greater load rating.

The Valley gearbox also has 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 design, the gears keep lubrication oil between your gears longer, reducing friction for increased load capability and longer life.
