Ball valves are making their contributions to the prosperity of the valve industry. Actually, there is a wide range of ball valve, which have been designed and manufactured based on different sizes, shapes, and structures or manufacturing materials and so on. Despite of the difference of specific specifications, all the ball valves are made to control the flow of liquids or gases. The on-and-off of the device determines the in-and-out of the flow.

Actually, the variations of the ball valves can be listed as follows. Firstly, the full port valve refers to the valve with a hole in the ball. The dimension of the hole is the same with the attaching pipe. As a result, the flow path is restricted to be rather smooth. Secondly, the reduced port valve occupies an opening in the valve ball, which is a little smaller than the dimension of the pipe. Such does help to slow down and minimize the forward flow with easy control. Thirdly, the trunnion valve is designed for the situations requiring the control of high velocity flow. Besides, there are some other valves designed with three-way or four-way. The flow can be altered inside of the valve itself. These valves are generally for more specific industrial requirements.

Even though the types vary a lot, some general components are the same. For example, they are made out of an outer shell with the valve ball, even the handle. The valve is up and down, or in rotation, for the control of the flow. And the valve handle control the valve ball. These handles can be driven by some mechanical motors, or can be manually operated. When the valve itself is pushed in the opening position, the hole in the ball would face the same direction as the valve shell and the flow go through. When the valve handle is moved to make the valve ball face the valve wall, the flow is immediately closed.
