There was also a safety valve ( pressure relief valve ) that allowed propane to escape when it expanded, as it got hotter outside. Those days are gone. Now propane tanks have a safety pressure valve inside the valve you hand turn. This interior valve will not allow you to let propane out of the tank unless it is connected to the correct fitting (which is usually your gas grill).
