What function does a valve serve in a piping system?

In a piping system, the primary function of a valve is to control the flow and pressure of liquids and gases. Valves can be adjusted to allow full flow, partial flow, or no flow at all, which enables operators to manage the transportation of fluids effectively. By regulating these parameters, valves help maintain desired conditions within the system, ensuring efficient operation and preventing damage or failure due to overpressure or uncontrolled flow.

For instance, in a cooling system, a valve can help restrict or allow the coolant flow based on temperature readings, ensuring optimal thermal management. This capability is crucial in various applications, including water supply systems, industrial processes, and HVAC systems, where precise flow control is essential for safety and efficiency.
