| Are you working on a chemical or | | | | fluid. Some of these industries are oil and |

| ball valves are parts of quarter turn valves | | | | manufacturers, pharmaceuticals processing and |
| or rotary valves. By turning a handle that is | | | | water and sewage plants.There are two types |
| attached to a ball that is inside the valve, | | | | of ball valves: the full port and the |
| the valves open. They then move in response | | | | standard port. A full port ball valve makes |
| to fluid or mechanical pressure.Inside the | | | | use of an oversize ball in order to allow |
| valve, there is a ball that has a port, which | | | | unrestricted flow. The size of the ball and |
| is actually a hole at the middle. When this | | | | the pipeline are identical, so this has a |
| hole is aligned with both valve ends, liquid | | | | lower loss of friction. A standard port, on |
| can flow easily through it. After the valve | | | | the other hand, has a slightly controlled |
| has been closed, the hole becomes | | | | flow and makes use of a smaller ball. This |
| perpendicular to the valve ends impeding the | | | | ball is smaller than the pipeline, and it |
| flow of liquid.Lots of different industries | | | | also has a smaller port. |
