For use with 4” STPs, the MLD product line is precision built, with unique construction features that provide busy stations with maximum flow rates and long service life. The MLD is offered in two models to match your exact application, ensuring accurate, nuisance-free operation critical to profitable station operation.
SPECIFICATIONS:
Two models: STP-MLD (blue) for gasoline and STP-MLD-D (tan) for diesel.
• Solid brass piston has 41.3mm of travel to move the leak detection poppet fully out of
the flow, offering minimum flow restriction and maximum flow rates.
• Burnished brass cylinder liner and polished stainless steel piston rod ensure smooth
operation and long life from the Teflon seal.
• Thermal compensation chamber of 94.2 cubic centimeters helps minimise thermal
contraction nuisance tripping.
Liquid Compatibility
Max. liquid viscosity: 70 SSU at 60°F (15°C).
• STP-MLD models are compatible with fuel mixtures containing up to 10% ethanol with
gasoline, and 20% MTBE, 20% ETBE or 17% TAME with gasoline, as well as diesel fuels,
fuel oils, kerosene, Avgas and jet fuels.
• STP-MLD-D models are listed for diesel fuels or kerosene only.
APPROVALS
Third party certified to comply with US EPA requirements 280.41 (B) and 280.44 (A) for
continuous monitoring of pressurised piping.
• Consult factory for other applicable approvals.
QUALITY CERTIFICATION
Franklin Fueling Systems is an ISO 9001 Certified Manufacturer.
ADVANTAGES
All models are capable of detecting line leaks equivalent
to 11.4 lph at 0.68 bar when installed properly with the
appropriate fuels. All models will signal detection of leaks
by restricting product delivery to less than 11.4 lpm and
taking more than 4 seconds to open.
• All models require 2 to 3 seconds to make a line test
when no line leaks exist and air is purged from piping
between the discharge of the MLD and the dispenser
solenoid.
• All models will remain in the “open” position during
product delivery to manifold, with discharge pressures as
low as 0.069 bar. All models will reset to “tripped” when
line pressure delay is below 0.207 bar with pump off.
• All models will detect leaks up to 3.04m above the MLD
installation point.
