Product Description

Product feature 

1.The double eccentric effect allows the disc to release from the seat immediately after the valve is opened

2.Reduced opening resistance, reduced wear, and improved seat life

3.Double eccentric butterfly valves can also use metal seats, which improves the application of butterfly valves in high temperature fields
