FCCV6 Ceramic Ball Valve

FCCV6 Ceramic Ball Valve, photo 1

KOWOV manufactures the FCCV6 single-seat ceramic ball valve for viscous, crystallizing, scaling and abrasive slurries in TiO₂, salt chemical and mining plants. Its no-dead-space flow path is intended to limit material accumulation in mining, hydrometallurgy, slag-slurry control and flue-gas-desulfurization duties

Design and construction

  • No-cavity design limits clogging, buildup and scaling in the flow path

    Fixed ball design delivers lower operating torque and stable control, even with dense slurries

    Shutoff class is listed as ANSI Class VI in the catalogue

    Scraper-type valve seat cleans the sealing surfaces automatically during every operation, preventing crystallization and scaling

    Blowout-proof stem design enhances operational safety in critical environments

    Automatic packing compensation structure maintains sealing force over time, extending service life

    The single-seat design is used for isolation and regulation of slurry, gas-solid and gas-solid-liquid service, including viscous, crystallizing, scaling and mineral slurries
