Which types of valves are commonly used in piping systems?

The types of valves commonly used in piping systems include ball, gate, and globe valves. Each of these valves serves a specific function and is suitable for different applications within a piping system.

Ball valves are favored for their ability to provide a tight seal and allow for quick shutoff of flow due to their quarter-turn operation. They are highly reliable and can be used in various media, making them a popular choice in many industrial applications.

Gate valves are primarily used for on/off service. They do not perform well in throttling or regulating flow, but they are excellent for providing a straight-line flow with minimal obstruction when fully open. This characteristic makes them suitable for applications where the valve is either fully open or fully closed.

Globe valves are designed for throttling applications, allowing for flow regulation. Their internal design provides a larger contact area with the flowing media, making them effective for controlling flow in pipelines while still allowing for a decent capacity when fully open.

Understanding the versatility and functionality of these types of valves helps in the selection process for various piping system demands, highlighting the importance of having a wide array of valve types available.
