What is a "flow control valve" used for in piping systems?

A flow control valve is primarily used to regulate the flow rate and pressure of fluids within a piping system. This component plays a crucial role in ensuring that the desired amount of fluid reaches different parts of the system while maintaining safe operating pressures. By adjusting the valve's position, operators can either increase or decrease the flow depending on the specific requirements of the system.

In addition to maintaining desired flow rates, flow control valves help prevent issues such as water hammer or excessive pressure that can lead to system failures. Proper regulation contributes to efficient system operation and longevity of the infrastructure.

The other options describe functions or features that are not associated with the role of a flow control valve. Filtering water is typically done by strainers or filters, aesthetic enhancements pertain to design elements unrelated to functionality, and measuring water usage is done with flow meters or similar devices rather than flow control valves.
