The ball valve series not only bears wide range of selected materials. Furthermore, the internal components of the valve are all nickel-plated on surface or made of the material 316, and the seal ring is made of the special polymeric material. Therefore, the valve not only features by favorable anti-corrosion and sulfide-resistance capacity. The fine fire-proofing, static-prevention and sealing performance are also enjoyed by it. With wide range of suitable pressure and temperature, the valve features by both all-diameter types and crinkled-diameter ones with diversified applicable driving units. It is a kind of ideal choice in chemical industry, petroleum refining industry, mining and conveying system of natural gas etc.
