The emergency shut-off valve or <br />"impact valve" is_ installed on the fuel line directly under the dispenser. It is intended to shut off <br />the flow of product in the event of impact and/or fire involving the dispenser. In normal <br />operation, the valve is left open, held in position by a fusible link. A shear section is located in <br />the upper half of the valve and should be installed level with the base of the dispenser. In an <br />emergency, the handle releases and the spring-loaded poppet assembly will swing shut. <br />Unibody construction. UL listed. <br />Double Tapped Bushings—FIG 184 Series <br />Used in pipe and tank fitting to reduce or adapt to a connection. Cast iron with <br />NPT threads. The duplex bushing is used to connect 2" pipe to dual 1/2" or 3/8" <br />lines. <br />Extractor—FIG 560 Series sm <br />Installed on the vent line of an underground storage tank. Extractor allows vent lines to be <br />manifolded and also allows removal of float vent valve (Fig. 317) for repair or replacement. <br />Various sizes available. CARB approved. <br />Float Vent Valve—FIG 317 Series <br />A main component of the Extractor/Float Vent Valve overfill prevention system. (Fig <br />560/317). Installed on a UST vent line.

Once seated, air flow becomes restricted which abruptly reduces the filling rate <br />and warns the operator to stop filling the tank. <br />Extractor Pipe Cap—FIG 578 Series <br />Used as a cover for the Extractor/Float Vent Valve overfill system. Installed on the riser <br />pipe at grade level normally inside a manhole. <br />Ball Valve (full port)—FIG 691 <br />Full port ball valve used for liquid handling with manual open -close in quick quarter -turn <br />handle operation.
