Abstract

A valve device includes a valve body having an inlet bore formed therein, the valve bore having a bore axis. A first semi-circular plate having a first axis is disposed within said inlet bore. Rotation of the first semi-circular plate about the first axis results in incremental displacement of the first semi-circular plate between an open and a closed position. A second semi-circular plate having a second axis is disposed within said valve bore. The first and the second axis are substantially coaxial wherein rotation of the second semi-circular plate about the second axis results in incremental displacement of the second semi-circular plate between an open and a closed position.
