What is a ball valve and how does it work?

A ball valve is a valve that controls the flow of fluid by rotating the ball. Its core component is a ball with a through hole. When the through hole of the ball is aligned with the pipeline, the fluid passes through; after rotating 90°, the through hole is perpendicular to the pipeline and the valve is closed.
Features:

Easy to operate (only 90° rotation is required).

Good sealing (metal or soft sealing material).

Suitable for high pressure, high temperature or corrosive media.
