The working principle of the ball valve is to achieve the purpose of opening or closing the valve by rotating the opening and closing parts (spheres) around the axis of the valve stem. Specifically, when the handle or drive is rotated, the valve stem will rotate the ball with it. When the internal channel of the ball is relative to the inlet and outlet channel of the valve, the valve is in a fully open state, and the medium can pass smoothly.
When the ball is rotated 90 degrees, so that its internal channel and the valve inlet and outlet channel vertical or staggered, the valve is in a fully closed state, the medium can not pass. In this way, by rotating the sphere, the valve can be opened and closed to control the flow of the medium.
