The emergency shut-off valve or "impact <br />valve" is installed on the fuel line directly under the dispenser: It is intended to shut off the flow of <br />product in the event of impact and/or fire involving the dispenser. In normal operation, the valve is <br />left open, held in position by a fusible link.

CARB approved. <br />Float Vent Valve—FIG 317 Series <br />A main component of the Extractor/Float Vent Valve overfill prevention system. (Fig 560/317). <br />Installed on a UST vent line.
