What does a fail-safe automatic closing valve do?

A fail-safe automatic closing valve is designed to enhance safety by shutting off the flow of gases or liquids when certain conditions are met or when it is activated. This is crucial in situations where a leak, rupture, or other hazardous event occurs, ensuring that the system can quickly contain the situation and prevent the release of potentially dangerous substances.

These valves are an integral part of systems handling compressed natural gas (CNG), as they help safeguard both the equipment and the surrounding environment. By acting swiftly to close off the flow, the automatic valve mitigates risks associated with pressure changes or unexpected system malfunctions.

While increasing gas pressure, preventing automatic shutdowns, or assisting in tank loading may be necessary functions in a gas delivery system, they are not the primary focus of a fail-safe automatic closing valve, which is specifically intended for the immediate cessation of flow to maintain safety.
