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

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.
