  • How does a ball valve work?

    The working principle of a ball valve is to control the flow of fluid by rotating the ball. The main components of a ball valve include the ball body, valve seat, valve stem, and handle. When the handle rotates, the valve stem drives the ball to rotate, thereby changing the shape of the channel inside the valve body and achieving fluid on/off control.
