What is the function of a valve in fluid systems?

The function of a valve in fluid systems primarily revolves around its ability to regulate, direct, or control the flow of liquids or gases within a system. Valves serve as critical components that enable operators to control the movement of fluids, ensuring that systems function efficiently and safely. They can open or close to allow or restrict flow, adjust the flow rate, or redirect it to different paths in a piping network.

The control provided by valves is essential for maintaining the desired operational conditions in various applications, from heating and cooling systems to industrial processes and fluid transport. By manipulating the flow, valves help achieve specific performance criteria, such as pressure regulation, temperature control, and flow distribution.

In contrast, while filtering contaminants, increasing fluid velocity, and measuring pressure are important functions in fluid systems, these tasks are typically handled by other components like filters, nozzles, or pressure gauges. Thus, the primary role of a valve distinctly focuses on flow management within the system.
