Patent ID: 6854710

Claim:
A valve assembly comprising: a valve body having a passage defining a first axis, and a bore defining a second axis disposed in crossing relation to the first axis, the bore having an inner surface defined by an inner periphery thereof, a first open end, and a second spaced apart open end; and a valve structure including a pair of radial flanges disposed at opposed ends with a solid web member extending therebetween, the radial flanges being configured to mount the valve structure within the bore for rotation about the second axis between a closed position, wherein the valve structure cooperates with the inner surface of the bore to obstruct movement of product through the passage, and an open position, wherein the valve structure is positioned relative to the inner surface of the bore so as to permit product movement through the passage, the radial flanges being structured and arranged so as to close the first and second open ends of the bore, wherein the valve structure includes a seal structure having a first seal portion extending lengthwise on one side of the web member and generally parallel to the axis of rotation of the valve structure, a second seal portion extending lengthwise on an opposite side of the web member and generally parallel to the axis of rotation of the valve structure, a third seal portion extending around one of the radial flanges, and a fourth seal portion extending around the other radial flange, thereby creating a seal between the valve structure and the bore to prevent movement of product therepast when the valve structure is in the closed position.
