What is the primary function of an excess flow valve when activated?

Regulates temperature
Limits the flow of propane
Increases pressure
Shuts off the gas supply

The correct answer is: Limits the flow of propane

The primary function of an excess flow valve is to limit the flow of propane in a system. This safety device is designed to activate in the event of a rupture or significant leak within the propane supply line. When the flow exceeds a predetermined threshold, the valve automatically closes or reduces the flow, thereby preventing excessive gas from escaping. This feature is critical in protecting the integrity of the propane system and ensuring the safety of the RV and its occupants. By controlling the flow, the excess flow valve helps to mitigate the risks associated with gas leaks, making it an essential component in propane systems.
