Ball valve is a throttling valve, due to the shape of the sphere with the ball columnar said, primarily for must be closed, and often switch when a fluid of throttling effect and design of the control flow, its main characteristic is effective throttle, the wiredrawing phenomenon is minimized and therefore reduce the valve and seat of immersion (impact), but because the seat is parallel to the streamline, fluid flow through the valve seat when the flow of change, will produce turbulence in the valve, and falling down force, caused by pressure drop is suitable for not only demanding the head no time, just can use.
