In the context of CNG, what is the role of valves?

In the context of compressed natural gas systems, valves play a crucial role in controlling the flow of gas. They are essential components that can be opened or closed to regulate how much gas moves through pipes or other passages in the system. This regulation is vital for maintaining safe operating pressures, ensuring efficient operation, and managing the delivery of gas to engines or other applications. Valves can also be used to isolate certain sections of the system for maintenance or emergency purposes, further emphasizing their importance in the overall safety and functionality of the CNG infrastructure.

The other options do not accurately describe the function of valves. Storing energy typically involves tanks or storage containers rather than valves. Measuring gas volume is handled by flow meters or gauges, while converting gas from liquid to vapor is the function of specialized equipment like vaporizers, not valves. Thus, recognizing the unique function of valves as flow regulators is fundamental in understanding their critical role in CNG systems.
