LLY-C series new type spiral wing metering refuelling nozzle is an upgrade version of LLY spiral wing type metering refuelling nozzle, according to the characteristics of liquid fuel calorific value, mechanical impurities, freezing point, density, ignition temperature, PH value, stability, corrosion resistance and other parameters, the metering uses the human body engineering principle, streamline design of appearance and professional Imported material properties and high-precision machining centres precision processing, through the performance of diagnostic test, has the feel good, clear, precise and stable walking characteristics, flexible, simple operation. As long as the measured with drop height of 2-10 meters between the surface and the instrument of medium, it can work normally, without any additional power source.
