Bright stem lined fluorine gate valve

  • Product Overview

    The fluorine-coated gate valve is a type of valve that uses a gate plate as the sealing element and achieves full opening or full closing through vertical up-and-down movement. It is used to cut off the flow of media in pipelines and is widely applied in industrial systems such as petroleum, chemical engineering, power, water supply and drainage, etc.
  • Applicable Condition

    Primarily used in pipeline cutting systems for industries such as petroleum, natural gas, chemical engineering, power generation, and water treatment. It is particularly suitable for situations where high sealing performance is required and frequent operations are not necessary.


  • Product Characteristics

    The structure is short in length and has low flow resistance; the sealing surface is less likely to be eroded when fully open; it can adopt metal hard sealing or soft sealing structures, and is suitable for high-temperature, high-pressure and corrosive media.
