 American Standard lined ball valve product use 

 Lined ball valve cavity and the sphere of production valve research and development of a strong Germany using high-pressure injection molding process is lined with corrosion-resistant, anti-aging of poly fluorinated ethylene propylene (F46), it has a reliable corrosion resistance and sealing. Widely used in chemical, petroleum, metallurgy, pharmaceutical and other industrial sectors, strong acids, alkalis and other corrosive media on the production process adjustment or cut off, the most obvious effect in the water treatment process control. 

 American Standard lined ball valve Features 

 1, FEP lining ball valve, has a very high chemical stability, can be applied to any strong corrosive nature of the addition to molten alkali metals and elemental fluorine. 
 2, full bore, floating ball structure, the valve can no leak shut down the entire pressure range, easier to pass the ball sweeping lines and piping of the piping system maintenance. 
 3, the opening and closing ball piece with the stem casting (forging) as one to eliminate the possibility of pressure changes caused by the valve stem out of the pressure inside the fundamental guarantee for the safe use of engineering. 
 4, compact and reasonable structure, the body cavity of minimum space, reducing the media retention, in addition, a special molding process, so that the sealing surface density is good, coupled with the word ring PTFE packing combination of the valve to achieve zero leakage. 
 5, two, three structure can be adapted to various requirements of piping systems and working conditions, of which three ball valve allows the main body, with both sides of the body separation can be achieved online fast replacement and maintenance.

 PTFE (F4) Suitable medium: strong acids, strong alkalis, strong oxidizers, etc.; use -200-180 degrees of temperature; 
 Features: excellent chemical stability, high heat resistance, cold resistance; low coefficient of friction, is an excellent self-lubricating materials, but lower mechanical properties, poor mobility, thermal expansion. 

 FEP propylene FEP (F46) Suitable medium: any organic solvents or reagents, dilute or concentrated inorganic acids, alkalis, ketones, aromatics, chlorinated hydrocarbons, etc.; temperature: -85-150 degrees; 
 Features: mechanical, electrical properties and chemical stability of the basic F4, but the outstanding merits of moving high impact toughness, and excellent weather resistance and radiation resistance.
