What is the term for protective devices used to manage gas flow in a plumbing system?

The term used for protective devices that manage gas flow in a plumbing system is more accurately known as gas valves. Gas valves are essential components that help control the flow of gas to different appliances, ensuring safety and proper function. They can be manually operated or automated and are crucial in regulating gas pressure and preventing leaks.

Gas regulators, while not the correct answer in this instance, are also important devices that manage pressure in a gas system by reducing the high pressure of storage or supply tanks to a usable level for appliances. Gas meters measure the volume of gas used, and gas striker plates pertain to different contexts, usually involving safety mechanisms in venting or combustion systems, rather than directly managing gas flow.

Understanding the role of these components helps in ensuring the safe and efficient operation of gas systems in plumbing.
