ABSTRACT:
A valve assembly including a valve body having an elongated passage through which product flows and a valve element which rotates about an axis extending generally normal to an axis defined by the passage in the valve body is disclosed. The valve element is mounted in the valve body passage to control product flow through the passage as a function of the position of the valve element. The diameter of a valve body bore within which the valve element rotates is equal to or greater than the passage it seals. A seal structure cooperates with the valve element to selectively seal the passage.
