Y <br />Inspection test port. <br />° Bottom tube threads on. <br />• Valve body: aluminum. <br />• Floats: polyethylene. <br />• Upper and lower tube: aluminum. <br />First stage flapper: zinc. <br />• Second stage flapper: acetal. <br />• Guide rod: stainless steel. <br />Autofimiter' <br />11 Automatic <br />Shut-off Valve <br />The Autolimiter® overfill prevention valve is <br />a self contained two-stage positive shut-off <br />valve designed to prevent the overfill of an <br />underground storage tank (UST) during a <br />gravity fed product delivery. When the liquid <br />level of the UST reaches about 92% of the <br />tank capacity during a fill, the product in the <br />tank raises the lower float of the valve. The <br />primary poppet of the valve is then released <br />and reduces flow to about 10% of normal <br />flow. The sudden reduction in flow created <br />by the closing of the primary poppet <br />provides "line shock" to the fill hose <br />notifying the transport delivery driver the <br />tank is nearing 95% capacity. The transport <br />delivery driver can then stop filling the tank, <br />disconnect and drain the delivery hose. The <br />upper float will close off the product flow <br />completely, providing positive shut-off <br />when the product level reaches 95% of <br />the tank capacity. <br />Models of the Autolimiter® exist to comply <br />with almost any underground storage tank <br />application including standard dual point <br />vapor recovery, dual point CARB EVR <br />vapor recovery, dual point biofuel <br />applications and single point coaxial fill <br />and vapor return applications. <br />Installer note: The Autolimiter' 11 is designed <br />solely for use in underground storage tanks. <br />For gravity drops only. No attempt should be <br />made to utilize this product with <br />aboveground storage tanks. The valve <br />would not function, creating a very <br />dangerous condition. <br />This product is for use in tight fill <br />applications only. <br />708-491-01' <br />Dual point <br />708-491-02' <br />Dual point <br />708-491-11" <br />Dual point <br />1708-491-12" <br />Dual point <br />708-491-21"' <br />Dual point <br />708-492-01' <br />Dual point <br />708-492-02' <br />Dual point <br />708-492-11" <br />Dual point <br />708-492-12" <br />Dual point <br />708-493101 <br />Coaxial <br />708-493-02 <br />Coaxial <br />708-494-04 <br />Dual point valveladapter kit <br />ULC MH21090. <br />"EVR Phase 1 Certification VR -101. <br />"'Biofuei approved model (E85 and biodiesel). <br />Outside valve body <br />Outside valve body <br />Factory installed <br />Factory_ installed <br />Outside valve body <br />Outside valve body <br />Outside valve body_ <br />Factory installed <br />Factory installed <br />Inside valve body <br />Inside valve body. <br />Outside valve body <br />RIVET ON TOP <br />PROTECTED <br />FLOAT SYSTEM <br />TEST PORT <br />THREAD ON <br />80TTOMTUBE <br />STANDARD <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Thread on <br />Rivet on <br />19 <br />
