In gas utilities, what is primarily controlled by the curb valve?

The curb valve plays a critical role in controlling access to the building's gas supply. Located at the property line and typically found near the sidewalk or at the curb, this valve allows utility personnel to shut off the gas flow to a building safely and efficiently during emergencies, maintenance, or repairs. By controlling the gas supply at this point, the curb valve ensures that gas can be quickly turned off to prevent leaks or fire hazards, thus allowing firefighters and emergency responders to operate safely.

While gas pressure, volume, and mixture are vital aspects of gas utilities management, these functions are primarily regulated by equipment and systems within the infrastructure, rather than through the curb valve itself. The curb valve's primary function is to regulate access rather than manage the internal characteristics of the gas. Understanding this distinction is crucial for effective emergency response and safety protocols in fire and utility management.
