What does the term 'EFV' signify in relation to gas service pipes?

The term 'EFV' refers to "Excess Flow Valve." This component is crucial in gas service pipes as it is designed to automatically shut off the flow of gas in the event of a significant leak or rupture in the system, effectively preventing gas from escaping into the environment. The EFV monitors the flow of gas and reacts to any abnormal increase in flow that surpasses a predetermined threshold, thereby protecting against potential hazards associated with gas leaks.

Understanding the function of the Excess Flow Valve is vital for maintaining safety in gas distribution systems. It serves an essential role in emergency management and risk mitigation by enhancing the overall integrity of the gas service system. Recognizing this helps in proper training and readiness for incidents related to gas service management.
