Triple offset butterfly valve

Triple offset butterfly valve are vital in applications where bubble-tight shut off is needed. In a few applications, bubble-tight shut off can't be accomplished utilizing twofold counterbalanced butterfly valves. A few applications don't give themselves well to conventional butterfly valves, for instance applications including savage chemicals or media with little particles inclined to obstructing valves and duct.
