What is the primary function of an Excessive-Flow Valve?

• A. A valve designed to close when the liquid or vapor passing through exceeds a prescribed tow rate
• B. A valve that maintains constant pressure in a gas container
• C. A valve that prevents backflow of gas in a piping system
• D. A valve that regulates temperature in gas storage

Answer: (A)

The primary function of an Excessive-Flow Valve is to close when the flow rate of liquid or vapor passing through it exceeds a predetermined threshold. This mechanism helps to provide a critical safety feature in LPG systems by preventing excessive leakage in the event of a line rupture or other uncontrolled discharge. By shutting off the flow, it minimizes the risk of accidents and enhances the safety of the entire system. Maintaining safety in LP-Gas applications is paramount, and Excessive-Flow Valves serve as a crucial component in achieving that by acting quickly to mitigate potential hazards.
