Propane Tank Question
Is this true? ""Propane tanks have a safety valve that shuts if a gas line should break and allow full flow.""

Any legal cylinder today, which requires a OPD (overfill prevention device)valve, will shut off if there is a sudden increase in the flow, such as a broken line. The propane passes thru a very small orfice that will immediately freeze closed if the normal flow amount is suddenly exceeded.
This feature is just part of the OPD valve safety features.
That's a bit misleading, the excess flow part is in the pigtail, not the valve. I have a full flow pigtail, and have no problem venting a cylinder at full blast through the OPD valve.
