The lined butterfly valve has simple structure, light weight, good sealing performance and long service life. It is usually used foron-off conditions and can also be used for regulate. It is widely used in various corrosive occasions such as acids, alkalis, and salts. Among them, the butterfly valve specially developed for desulfurization and denitration in the thermal power industry adopts a pinless structure with a bottom rotation, the center position of the valve plate is more accurate, and the sealing performance is better; the valve plate is made of 2507 or 1.4529 material, which has greatly improved corrosion resistance as well as anti-abrasion performance.
