Q41J-10The inner cavity and ball of floating rubber lined ball valve adopt high-pressure injection molding process, lined with corrosion-resistant and aging resistant rubber, so it has reliable corrosion resistance and sealing performance. It is widely used in chemical, petroleum, metallurgy, medicine and other industrial sectors to realize the regulation or cut-off of acid, alkali and other strong corrosive media in the production process. The effect of Zui is obvious in the water treatment process control.

1. The ball valve with rubber lining layer has high chemical stability and can be applied to any strong corrosion property except "molten alkali metal and element fluorine"
2. With full bore and floating ball structure, the valve can be closed without leakage in the whole pressure range, which is more convenient for ball cleaning and pipeline maintenance of pipeline system
3. The ball part of the opening and closing part and the valve rod are cast (forged) as a whole, which eliminates the possibility that the valve rod will burst out of the pressure bearing parts due to the pressure change, and fundamentally ensures the use safety in the project
4. The structure is compact and reasonable, and the inner cavity space of the valve body is small, which reduces the medium retention. In addition, the special molding process makes the sealing surface have good density, and the herringbone ring PTFE packing combination makes the valve achieve zero leakage
5. The two-piece and three-piece structure can adapt to various pipeline systems and working conditions with different requirements. The three-piece ball valve allows the main valve body to be separated from the two-sided valve bodies, which can realize on-line rapid replacement and maintenance
