The electric hard-sealed butterfly valve adopts a triple eccentric structure, and there is no friction transmission between the sealing surfaces. It has the characteristics of wear resistance, good mechanical performance, high temperature resistance, high pressure resistance and long service life. It is divided into wafer type and flange according to different connection methods. It can be used in a variety of different pipelines and places with corrosive media. Electric hard seal butterfly valve seals are made of metal materials or other hard materials, such as stainless steel + cemented carbide. They are widely used in chemical industry, environmental protection treatment, gas, oil, steam, water and corrosive medium temperature ≤550℃ In the various pipelines of the medium, it can be used as a switch cut off or percentage adjustment!
