  • Seat centerline operated butterfly valve
    Patent number: 4324383
    Abstract: The actuator shaft of a butterfly valve rotates 90 degrees to open or close an associated flow interrupter. As the shaft rotates its 90-degree motion is imparted to associated link members and the flow interrupters that are operably connected to the shaft. Thus, a drive link, secondary shaft and vane, as well as the support trunnions, are rotated simultaneously. This arrangement permits the seating of the seal on an axis which coincides with the axis of the actuator shaft and the sealing effected is bidirectional.
