Product overview

  • 1732259355504
  • The FCCV2 series high temperature ceramic ball valve is specifically developed for working conditions where standard ceramic valves cannot withstand extreme heat and rapid thermal shock. With a maximum service temperature of up to 456°C, this valve ensures safe and reliable operation in environments that combine high temperature, strong corrosion, and severe abrasion. It is widely applied in industries where conventional metal or alloy valves quickly fail, providing longer service life and reduced maintenance costs
    The FCCV2 uses a hard-sealed structure without graphite or PTFE sealing rings. The ceramic ball and seat are ground as a pair. A live-load packing system maintains packing force as wear occurs, while upper and lower sliding bearings locate the stem during thermal cycles

Design and construction

  • No sealing rings, suitable for high temperatures, organic solvents, and strong corrosive
    environments
    Fully hard-sealing surfaces, no non-metallic materials like graphite or PTFE
    "Live load" in the packing box maintains constant load under wear for long packing life
    Upper and lower sliding bearings in the packing box prevent valve displacement and
    packing squeeze, enhancing packing longevity

High-temperature design

The FCCV2 is used for isolation and regulation of slurry, gas-solid and gas-solid-liquid service involving corrosion, abrasion or erosion. The catalogue lists service above 180 °C
