Eccentric Butterfly Valves

The connection between upper and lower valve shaft and butterfly valve uses heterogeneous blind hole and deformed shaft. During on-off, floating no-pin connection, reducing interference region between disc and seat and decreasing torque greatly. The floating structure of disc realizes manufacturing techniques and using functions of eccentricity. According to the structure, eccentric butterfly valve can be classified into single-eccentric butterfly valve, double eccentric butterfly valve, tri-eccentric butterfly valve and variable eccentric butterfly valve.   

China butterfly valve manufacturer Durlmark provides various eccentric butterfly valves to meet different requirements: ductile cast iron/stainless steel/aluminum bronze/carbon steel, 12 inch/72inch, butt-welding/flange connection.
