  • 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.

  • What are the Advantages of Floating Ball Valve Compared with Other Valves?

    The key to floating ball valve is that its ball has no fixed shaft support running through it. When the valve is closed and needs to be sealed, it is the pressure generated by the liquid or gas flowing in the pipeline that pushes the ball tightly against the sealing surface.
