A ball valve is a quarter-turn valve that uses a rotating ball with a hole to control the flow of fluid through a pipeline.
## Detailed Explanation
Ball valves are one of the most widely used industrial valves. They provide fast shut-off and reliable sealing, making them ideal for applications where tight closure is required.
The valve consists of a spherical ball with a bore through its center. When the handle is turned 90 degrees, the hole aligns with the pipeline to allow flow or blocks it to stop flow. ## How It Works When the valve is open, the hole in the ball aligns with the pipe, allowing fluid to pass through. When closed, the solid part of the ball blocks the flow completely.
## Types of Ball Valves
* Floating Ball Valve * Trunnion Mounted Ball Valve * Full Port Ball Valve * Reduced Port Ball Valve
## Applications
* Oil and gas pipelines * Water treatment systems * Chemical processing * Power plants
## Advantages
* Quick operation * Excellent sealing * Long service life
## Disadvantages
* Not ideal for throttling * Can be more expensive than gate valves
## FAQ
### What is a ball valve used for? Ball valves are used to start or stop fluid flow in industrial pipelines.
### How long does a ball valve last? A high-quality ball valve can last 8–10 years depending on usage conditions.
### Is a ball valve better than a gate valve? Ball valves provide faster shut-off, while gate valves are better for gradual flow control.
