Frequently Asked Questions
Q
What is the maximum sealing class of the single-seat ceramic ball valve?
The single-seat ceramic ball valve achieves a high sealing level of up to ANSI Class VI, guaranteeing tight shut-off and completely leak-free performance even in demanding slurry and corrosive media applications.
Q
What types of media is the ceramic ball valve suitable for?
The valve is designed for a wide range of challenging media including highly viscous slurries, crystallizing or scaling slurries, mineral slurries, gas-solid particulate media, and gas-solid-liquid three-phase media. It is also suitable for corrosive media such as strong acids (HCL, H₂SO₄, HNO₃) and alkalis (NaOH).
Q
How does the scraper-type valve seat prevent scaling and clogging?
The scraper-type valve seat is engineered to automatically clean the sealing surfaces during every open and close operation. This self-cleaning action removes any crystallized deposits or scaling material, preventing buildup that could otherwise compromise valve performance or cause blockages.
Q
What ceramic materials are available for the ball and seat, and which is recommended for strong acid service?
Available ceramic materials include Y-ZrO₂ (Y-TZP), Mg-ZrO₂ (M-PSZ), 90/95/99 Al₂O₃, Si₃N₄, and SiC. For strong acid service such as HCL, H₂SO₄, and HNO₃, ZrO₂ and 99.9% Al₂O₃ are rated Grade A (no corrosion) and are the recommended choices. SiC also shows excellent resistance across most acid media.
Q
What nominal diameter range is available, and what are the available ball core types?
The valve is available in nominal diameters from DN15 (1/2") to DN200 (8"), with larger sizes up to DN250 (10") also offered. Ball core options include O-type (full bore), V60°, V45°, and V30° configurations to suit different flow regulation requirements.
Q
What industries commonly use the FCCV6 ceramic ball valve?
The FCCV6 is widely used across industries including Titanium Dioxide (TiO₂) production, salt chemical processing, petrochemical refining, mining and mineral processing, dye manufacturing, hydrometallurgy, environmental protection (FGD systems), and steelmaking & smelting — wherever wear-resistant, corrosion-resistant, and reliable slurry control is required.
