What is the primary purpose of installing valves in a gas piping system?

The primary purpose of installing valves in a gas piping system is to control the flow of gas through the piping. Valves allow for the regulation of gas movement, enabling users to start or stop flow as necessary, redirect gas to different sections of the piping system, or adjust the flow rate depending on operational requirements. This flow control is crucial in maintaining safety and efficiency within the system, as it ensures that gas can be delivered where it is needed while preventing unauthorized or unsafe gas escapes.

While controlling gas pressure is an important aspect of a gas system, it is primarily managed through regulators rather than valves. Preventing gas leaks is a critical safety measure, but valves themselves do not directly stop leaks; they can help by securely sealing off sections of piping if needed. Gas odorization is a safety feature that allows for the detection of gas leaks through a distinct smell, but it is not related to the specific function of valves in controlling gas flow.
