Ball valves are greatly helping the valve industry to be prosperous. Ball valves come in a wide array of sizes, shapes, materials, etc. They are designed to meet various needs of the consumers. However, they all share one basic job. That is to control the flow of liquids and gases. Turning the device on and off determines the overall flow.
The variations of the ball valves are seen here. A full port valve has a hole in the ball. The hole size is the same as that of an attaching pipe. This restricts the flow path and is, thus, rather smooth. A reduced port valve occupies a small opening in the valve ball. It is a little smaller than the pipe. It helps to slow down and minimize the flow with ease. The trunnion valve is good for situations that require a high velocity flow. In addition, there are some valves that are designed with a three-way or four-way. These valves are not as common as they are used for specialized equipment.
Even though the ball valves vary, they generally have the same components. They all have an outer shell with the valve ball. To control the flow the valve moves up and down as well as rotors. There is a control for the valve to help with the flow. Some are motorized while others are manual. When the valve is open, the ball will face the same direction in order to allow the flow to go through. The flow is closed as soon as the handle is moved in the opposite direction.
