company news about The "hellish challenge" of the butterfly valve

  The butterfly valve not only transports clean water, but also quietly withstands pressure in many "high-tech" scenarios that you might not expect:

  At a temperature of -196℃ (LNG liquefied natural gas): When natural gas is frozen into liquid for transportation, the temperature is so low that it can cause ordinary steel to crack like glass. The specially designed ultra-low-temperature butterfly valve uses special anti-freezing materials and an extended valve stem to ensure it can still rotate flexibly in an icy world.

  With high concentrations of corrosive acids and bases (chemicals): Many chemical solutions can corrode metals. Engineers will give the butterfly valve a "plastic coating" - a fluorine-coated butterfly valve. The inside of the valve body and the butterfly plate are all covered with the so-called "plastic king" - PTFE , making strong acids and strong bases have no effect on it.
