Understanding valves, their types, applications, and maintenance can help select the right valve for a specific need and ensure their longevity and efficiency. This comprehensive guide aims to provide an in-depth look at valves, covering everything from basic definitions to advanced applications.

What is a Valve?

A valve is a device that regulates, directs, or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings but are usually discussed as a separate category.

History of Valves

The history of valves dates back to ancient civilizations, where primitive valves were used to control water flow in irrigation systems. With the advent of the Industrial Revolution, valve technology saw significant advancements, leading to the development of modern valves that can handle high pressures, temperatures, and corrosive materials.

Types of Valves

There are numerous types of valves, each serving different purposes and applications. Here are some of the most common types:
