Abstract:
Some embodiments of a shutoff valve system for a fluid flow system can include a plug assembly that is biased to adjust from a first position in which the fluid flow path is open to a second position in which the fluid flow path is closed. The plug assembly may automatically adjust from the first position to the second position in response to a downstream pressure condition.
