Fluorine valve cavity and the sphere are high-pressure injection molding process is lined with corrosion resistance, aging resistance of polyvinyl fluoride, has the corrosion resistance and reliable sealing. Widely used in chemical, petroleum, metallurgy, pharmaceutical and other industrial sectors, to achieve the production process, acid, alkali and other strong corrosive mediators or cut off, the most obvious in the process control used in water treatment effect.
Product features:
■ uses ball valve fluorine lining layer, the chemical stability is high, can be used in addition to "molten alkali metals and elemental fluorine" any other strong corrosive nature
■ a full-bore, floating ball valve structure, can be carried out in the whole range of pressure without leaking off, maintenance more convenient pipeline pigging and pipeline
■ headstock piece ball and valve casting (forging) as a whole, to eliminate the pressure change due to stem out the possibility of pressure within the case, from the fundamental guarantee for the safety of
A compact and reasonable structure, the inner cavity of the valve body minimum space, reduces the medium left, in addition, a special molding process, so that the sealing surface density is good, plus the V PTFE packing, the valve to achieve zero leakage
■ two type, three type structure can adapt to the different requirements of the pipeline system and working conditions, including three piece ball valve allows the main valve body separation and on both sides of the body, can achieve rapid replacement, repair Online
