This article presents an overview of valves, their functions and the commonly used types of valves in the industry. The design principle, application areas, benefits and disadvantages of various types of valves are presented. Different methods of valve classification are also discussed to highlight the key considerations in valve selection.<\/strong><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A valve is a mechanical device used in fluid systems to control, direct, isolate, mix, or regulate the flow or pressure of a fluid, by modifying the passageway through the pipe. When a valve is in the open position, the passageway is unobstructed and the fluid flows in a direction from higher pressure to lower pressure. By partially or fully obstructing the passageway through the valve, the flow can be reduced or completely stopped.<\/p>

Technically, valves are pipe fittings but due to their critical function, wide variety of types, and operation options they are generally considered separately from other fittings. Valves are often the costliest components of the piping system in a plant; the cost of valves can be as much as 30% of the overall piping cost.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Valves play a critical role in increasing efficiency, improving quality control, and ensuring safety and reliability of a process. The primary consideration in valve selection is the desired function of the valve. Valves are incorporated into a piping system for one or more of the following reasons:<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
