Which of the following is a benefit of using control valves in engineering?

The benefit of using control valves in engineering primarily lies in their ability to improve energy efficiency. Control valves are essential components in various systems, allowing for the regulation of fluid flow and pressure within pipelines and processes. By enabling precise control over the flow rate or pressure, these valves can optimize the performance of pumps and compressors, reducing unnecessary energy consumption.

When control valves modulate flow based on system demands, they help maintain the desired operational conditions without forcing equipment to work harder than necessary. This not only conserves energy but also extends the lifespan of the equipment by minimizing wear and tear. Therefore, the capacity of control valves to enhance energy efficiency is a crucial aspect of their role in systems management and engineering practices.
