Special industrial butterfly valve is characterized by high temperature resistance, high applicable pressure range, large nominal diameter of valve, carbon steel valve body, and metal ring instead of rubber ring for sealing ring of valve plate. The large high-temperature butterfly valve is welded with steel plate and is mainly used for the flue and gas ducts of high-temperature media.

Integral metal hard seal butterfly valve Integral metal hard seal butterfly valve is mainly used in high, medium and low pressure, high temperature and low temperature pipelines to cut off and regulate. Integral metal hard seal butterfly valve is used in petroleum, chemical, metallurgy, power and other industries. Main features: 1. Compact structure, small size, light weight, flexible opening and closing. 2. Three eccentric structure is adopted, and the sealing performance is reliable after optimized design
