• Work with the flow of natural gas as the sensing source
• Activate when a line rupture causes an excess flow condition
• Automatically reset and resume normal operation after repairs are made using a slight gas bypass to re-pressurize the line
• Non-bypass models are also available. These models are reopened by correcting the excess flow condition and manually applying back pressure to the line and valve.
