There are a lot of types that can be used in different ways. One particular type of valve would be the double offset high performance butterfly valve. This valve is specifically used in large pipes, and is described as a disk rotating on a diametrical axis inside a pipe, also used as a throttle valve or a damper.

The double offset high performance butterfly is a sort of device that controls the flow, normally used to administer a certain fluid that would flow through a certain section of a pipe. This valve is similar (with regards to operation) to a ball valve. The double offset high performance butterfly, having a flat circular plate, is positioned in the center of the pipe, and the plate has a rod through it that is attached to a handle on the outside of the valve. This valve works by rotating the handle, and turning the plate over either in a parallel position, or perpendicular to the flow.
