Ultra high temperature butterfly valve due to choose the suitable high temperature resistant materials and unique structure, under low pressure difference occasions, the highest temperature can reach 900 ℃. Replaced the traditional inner loop water cooling structure and lining refractory mortar backward structure; This series of ultra high temperature butterfly valve has simple structure, easy operation, large aperture, light weight, etc. Body with split fission seat structure, ensure the characteristics of the leakage is small, can be widely used in sulphuric acid, metallurgy, petrochemical industry system of blast furnace air distribution, boiler pipes, to control the fluid to adjust use; Can choose worm gear drive mechanism, to meet the requirements of process control.
