Slim movie coatings are lighter than sprayed coatings by around four grams, and don't alter tolerances as much. Tough slender film coatings for instance diamond-like carbon are only 20 microns thick, nonetheless are incredibly long lasting. In 2007, NASCAR rule improvements would require using unleaded gasoline as opposed to the leaded gasoline which has been used. This will probably need the use of slender movie coatings about the valve stems and seats to stop put on.

Zirconia balls also aspect resistance to abrasion and corrosion and are chemically inert to molten metals, organic and natural solvents, caustics, and most acids.

A unique characteristic of ValvTechnologies V series integral seated mounted carbide coated ball valves is neither a floating ball nor trunnion layout, which could take care of all concentrations of solids. This is significant as solids bring about seat problems and loading in floating and trunnion ball valve models.
