Triple-eccentric butterfly valve adds another unique angle offset on the double-eccentirc butterfly valve to allow the disc to seal against the seat with no friction during the 90 degrees opening and closing process. It provides a more cost-effective solution to services require high temperature, high pressure or low temperature. Triple-eccentric butterfly valve is widely used in the pipline system of metallurgy industry, power industry, petrochemical industry, water and sewer system, and municipal construction requires strict medium control.
