Its main feature is that the ball has no supporting shaft, the ball is supported by the valve seats at both ends of the valve inlet and outlet, and the valve stem and the ball are movablely connected.
The ball of this ball valve is held between two valve seats and is in a "floating state". The ball can rotate freely between the two valve seats through the valve stem with the help of a handle or other driving device. When the flow channel hole of the ball is aligned with the valve channel hole, the ball valve is in an open state, the fluid flows smoothly, and the fluid resistance of the valve is minimal. When the ball is rotated 90C, the flow channel hole of the ball is perpendicular to the valve channel hole, and the ball valve is in a closed state. Under the action of fluid pressure, the ball is pushed to the valve outlet end of the valve (referred to as the valve seat for short), making it compressed and ensure sealing.
