ball vlave summary

The valve structure can be designed casting or forging type body, seat is Metal-to-metal type, and have floating ball and trunnion

mounted ball form. Overlay on ball and seat seal area are made with HVOF The HVOF process is use of combustible gas and oxygen combustion in special chamber, and then generating high temperature and speed flame, the speed about 1500~2000m/s, by an intert gas the powder is sent into the combustion chamber, and the powder will be melted down or half melted and its speed will be increased to 300~500m/s

or higher, so that the coating layer will be high strength, compact and berrer quality.

The HVOF is use of a DC arc between cathod and anode, the arc heat and ionizate work gas into high temperature plasma, and spray out plasma flame form nozzle. When powder is sent into plasma flame, it will be melted down, accelerated and sprayed on pretreatment

base material, and formed into coating.
