Most regulators utilize a simple mechanical principle a diaphragm or membrane that moves in response to pressure changes. When gas enters the regulator, it pushes against the diaphragm, which in turn opens or closes a valve to maintain a steady output pressure. Modern regulators often come with safety features such as overpressure protection and shut-off valves, which automatically cut off the gas supply if the pressure exceeds safe levels.
