At the discharge end of the transfer hose, which type of valve must be installed?

The requirement for a listed quick acting shutoff valve at the discharge end of the transfer hose is essential for safety and efficiency in LP-Gas dispensing operations. This type of valve is designed to close rapidly, allowing for immediate cessation of gas flow, which is crucial in emergency situations or when the transfer process needs to be stopped quickly. The quick acting nature of this valve minimizes the risk of leakage and potential hazards associated with pressurized gas.

Using a valve that fulfills this specification ensures compliance with safety regulations and enhances the control over the dispensing process. In contrast, other types of valves, like quarter turn ball valves or standard globe valves, do not provide the same level of rapid response and control needed for safe LP-Gas dispensing.
