1. The inner cavity of the valve body and the valve core are high-temperature molded or coated with 2.5-6mm thick fluoroplastic, which can withstand various strong corrosive media such as liquid chlorine, acid, alkali, salt, aqua regia, organic acids, etc;
　　2. The valve seat seal adopts internal and external pressure high-temperature sintered PTFE soft seal valve seat, which has the characteristics of no looseness, no detachment, no deformation, and good sealing performance;
　　3. The valve core and valve stem are integrated to prevent the valve stem from flying out;
　　4. The valve seat sealing ring adopts a unique elastic lip sealing structure with self compensating function.

Widely used in industrial control systems such as chlor alkali, petrochemical, metallurgical, pharmaceutical, power, and fertilizer industries, for controlling strongly corrosive gases, liquids, and other media such as acids and alkalis.
