A gas pressure regulator is designed to control the pressure of gas flowing to appliances. Its primary function is to reduce the high pressure from the gas supply line to a suitable level that can be safely used by heaters, stoves, or other gas-operated appliances. This regulation ensures that the appliances receive a consistent and safe amount of gas to operate efficiently.

Maintaining the correct pressure is crucial, as too high a pressure can damage appliances or cause unsafe combustion conditions, while too low a pressure may prevent appliances from functioning properly. The ability to adjust gas pressure as needed helps enhance safety and performance in gas systems.
