A handle butterfly valve is a flow control device that uses a disc as a shut-off and is typically used to control the flow of gases, liquids, and particles. The handle butterfly valve works by turning the handle so that the bearing attached to the disc rotates, so that the disc rotates along the axis of the pipe. When the disc is at a certain angle to the pipe, it can truncate, control or adjust the flow rate of the medium, so as to achieve the purpose of controlling the flow rate.
