When the liquid level of the UST reaches about 92% of the tank capacity during a fill, the product in the tank raises the lower float of the valve. The primary poppet of the valve is then released and reduces flow to about 10% of normal flow, The sudden reduction in flow created by the closing of the primary poppet provides "line shock" to the fill hose notifying the transport delivery driver the tank is nearing 95% capacity, The transport delivery driver can then stop filling the tank, disconnect and drain the delivery hose. The upper float will close off the product flow completely, providing positive shut-off when the product level reaches 95%o of the tank capacity. Models of the Autolimitere exist to comply with almost any underground storage tank application including standard dual point vapor recovery, dual point CARR EVR vapor recovery, dual point blofuel applications and single point coaxial flit and vapor return applications. Installer note: The Autolimitere 11 is designed solely for use in underground storage tanks. For gravity drops only. No attempt should be made to utHize this product with aboveground storage tanks. The valve would not function, creating a very dangerous condition. This product is for use in tight fill applications only, 708-491-01' Dual point Outside valve body 708-491-027 Dual point Outside valve body 708-491-11" Dual point Factory installed 1708-491-12" Dual point Factory installed 708-491-21"' Dual point Outside valve body 708-492-01' Dual point Outside valve body 708-492-02' Dual point Outside valve body 708-492.11" Dual point Factory, installed 708-492-12" Dual point Factcry Installed 708-493-01 Coaxial inside valve body 708-493.02 Coaxial Inside valve body 708-494-04 Dual paint valveladapter kit Outside valve body 'ULC MH210901 "EVR Phase 1 Certiflcation VR -101.
