What does a natural gas regulator do?
What does a natural gas regulator do? Throughout the gas delivery system, from the well to the stove burner, regulators are used to adjusting the pressure to ensure safety. I discuss why natural gas pressure regulators are used in a delivery system in this back to basics entry.
Natural Gas Regulators
After natural gas makes its way out of the well into gathering and transmission systems and gate stations, it ultimately enters distribution lines (or “mains”).

While gas is in the distribution system, regulators control the flow from higher pressure to lower pressure. Regulators sense if the pressure in a line drops below a specified set point and opens, allowing more gas to flow. On the other hand, if demand rises above a set point, the regulator will close to adjust the downstream pressure.
When natural gas leaves the main, it travels through a “service line” to reach homes or businesses. This service line is likely to be polyethylene, perhaps an inch or less in diameter, and ranges from about 60 PSI to ¼ PSI. Once the gas reaches the home or business meter, it passes through another residential or light commercial regulator to reduced the pressure under ¼ PSI and is measured in a water column.
Throughout the gas delivery system, from the well to the stove burner, regulators are used to adjusting the pressure to ensure safety.
