A Triple Offset Butterfly Valve has 3 separate offsets. Two of the offsets apply to the location of the shaft in respect to the centerline of the bore and the centerline of the disc/seat sealing surfaces. The third offset is the design in the axis of the seat cone angle.Triple Offset Butterfly Valves are essential in applications where bubble-tight shut off is required. In some applications, bubble-tight shut off cannot be achieved using double offset butterfly valves.
