Design Features <br /> The MLD is offered in three models to match your •Three models for the exact application:STP-MLD <br /> exact application, ensuring accurate, nuisance free (blue In color)for gasoline,STP•MLD-D (tan in <br /> operation critical to profitable station operation. color)for diesel, and STP-MLD-E(gray in color) <br /> for some expandable pipe applications. <br /> • Solid Brass Piston has a full 1.5/8"of travel to move <br /> the leak detection poppet fully out of the flow to offer <br /> minimum flow restriction and maximum flow rates. <br /> • Burnished Brass Cylinder Liner and Polished <br /> Stainless Steel Piston Rod ensure smooth <br /> operation and long Teflon seal life. <br /> • Thermal Compensation Chamber of 5.75 <br /> cubic inches of volume helps minimize <br /> thermal contraction nuisance tripping. <br /> Liquid Compatibility <br /> • Max liquid viscosity:70 SSU®607(15'Q <br /> �s • STP-MLD &STP-MLD-E models are listed for fuel mixtures <br /> containing up to 100% Ethanol or Methanol, and 20% <br /> MTBE,20% ETRE,or 17% TAME with gasoline,as well <br /> Burnished Brass <br /> as diesel fuels,fuel oils,kerosene, avgas, and jet fuels. <br /> •.0 -,ry. • STP-MLD-D models are listed for <br /> ,( Cylinder Liner diesel fuels or kerosene only. <br /> Operational Features <br /> Brass Piston <br /> {[ f • All models are capable of detecting line leaks <br /> equivalent to 3 gph at 10 psi when installed <br /> properly with the appropriate fuels. <br /> 4. Teflon Seals • All models will signal detection of leaks equivalent <br /> to 3 gph at 10 psi or greater by restricting <br /> Thermal ,y.f productdelivery to less than 3 gpm. <br /> Contraction _ • All models require 2 to 3 seconds to make a line test when <br /> Compensation ^i. _ ,i ., no line leaks exist and air is urged from piping between <br /> Chamber ": _ the discharge of the MLD and the dispenser solenoid. <br /> T'�s • All models will indicate detection of leaks <br /> equivalent to 3 gph at 10 psi or less by taking <br /> longer than 2 to 3 seconds to open. <br /> f??¢1 • All Models will remain in the "open" position <br /> during (pump on)product delivery to manifold <br /> discharge pressures as low as 1 psi <br /> • All models will detect leaks up to approximately 10 <br /> .r ` feet above the point that the MLD is Installed. <br /> • All models will reset to the "tripped" position when <br /> _ (pump off)line pressure decay below about 3 psi <br /> Approvals <br /> Ground &Polished • Third Party certified to comply with US EPA <br /> Stainless Steel requirements 280.41 (B)and 280.44(A)for <br /> Piston Rod continuous monitoring of pressurized piping. <br /> 44 • All MLD models are UL and cUL listed for <br /> installation into all 4"FE Petro Submersibles <br /> as well as most competitive models. <br /> • Consult factory for other applicable approvals. <br /> Quality Certification <br /> • Franklin Fueling Systems is an ISO 9001 <br /> Certified Manufacturer. <br /> 24 <br />
