Double Offset Butterfly Valve Manufacturer

These valves are popular regarding accuracy and performance. From the valve’s body center, the butterfly valve has two offsets. The shaft’s axis then balances the central line of the body seal and discs seat.

The valve is in the center, whereas the shaft axis is eccentric to the pipeline. The position of the disc in double offset butterfly valves gives rise to the cam action. It causes friction when the seat is raised from the seal.
