What is the function of a pressure regulator in a gas distribution system?

The function of a pressure regulator in a gas distribution system is to control the pressure of the gas delivered to consumers. This is crucial because gas needs to be supplied at a consistent and safe pressure level to ensure the proper functioning of appliances and systems that use gas. If the pressure is too high, it can lead to dangerous situations such as leaks or damage to equipment. Conversely, if the pressure is too low, it may not meet the performance requirements of the appliances being used. Thus, pressure regulators are vital in maintaining the appropriate gas pressure, ensuring safety and efficiency in the distribution network.
