Q41F lined ball valve details: 
 , Q41F lined ball valve product use 

 Lined ball valve cavity and the sphere of 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 other industrial sectors as chemicals, petroleum, metallurgy, medicine, strong acids, alkalis and other corrosive media regulation in the production process or cut off, the effect in the water treatment process control most obvious 

 Second, the Q41F lined ball valve Features 

 1, FEP lining ball valve, high chemical stability, can be applied to molten alkali metals and elemental fluorine, any strong corrosive nature, full bore, floating ball structure, the valve can the entire pressure range, no leak shut down, and easier to pass the ball sweeping line of the piping system and pipeline maintenance, open and close the ball with stem casting (forging) as one, and put an end to the red due to pressure changes caused by stem the pressure within the possibility of a fundamental guarantee for the use of security engineering, compact and reasonable body cavity of minimum space, reducing the media retention, in addition, a special molding process, so that the sealing surface density good, coupled with the word ring PTFE packing combination of the valve to achieve zero leakage, two-piece, three structures can be adapted to various requirements for piping systems and working conditions, including three ball valve allows the main valve body with the separation of both sides of the body, online fast replacement, repair 

 Third, the Q41F lined ball valve implementation of standards 

 Design standard: GB12237 
 Structural length: GB12221 
 Flange Standard: to JB/T79-94 GB9113.1-26 
 Inspection and test: JB/T9092-99
