Abstract
An improved valve assembly is provided for dispensing liquid from bulk containers. The valve assembly includes a tubular housing defining a cylindrical chamber open at its ends. The housing is connected with an opening in the liner of the container to afford fluid communication between interior of the liner and the chamber. The valve assembly includes a valve shaft having end portions rotatably connected with the housing and a cylindrical body portion extending transversely across the chamber. The shaft body portion contains a slot extending between the end portions for receiving a generally circular butterfly valve disc. The disc has a maximum diameter corresponding with the diameter of the chamber and a minimum diameter corresponding with the length of the slot. An O-ring is connected with the outer edge of the disc. When the valve shaft is rotated to an open position, the disc is arranged longitudinally of the chamber to permit the flow of liquid from the container through the chamber. When the valve shaft is rotated to a closed position, the disc is arranged transversely of the chamber to prevent liquid from flowing therethrough.
