Propane Tank Question
Is this true? ""Propane tanks have a safety valve that shuts if a gas line should break and allow full flow.""
Forum Discussion
There is a spring loaded shutoff vlave in the end of OPD service valve that will not allow propane flow unless a hose is attached that pushes the spring loaded shutoff valve open.
There is a ball check valve inside the ACME nut that moves closed when opening a OPD valve until downstream pressure builds up/equalizes and then the ball check valve moves back to center position allowing full flow.
If OPD opened to quickly the ball check valve will stay in closed position.
If a downstream leak should occur the ball check valve moves from center to closed position.
