❓ Frequently Asked Questions
Q
What is the maximum sealing level 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 under demanding operating conditions.
Q
What types of media is this ceramic ball valve suitable for?
It is designed for isolation and flow regulation of various slurries, gas-solid particulate media, and gas-solid-liquid three-phase media. It is especially suitable for highly viscous, crystallizing, or scaling slurries and mineral slurries in industries such as titanium dioxide production, petrochemicals, mining, and environmental protection.
Q
How does the scraper-type valve seat prevent scaling and crystallization?
The scraper-type valve seat is engineered to automatically clean the sealing surfaces during every open and close operation. This self-cleaning action effectively removes deposits, preventing crystallization and scaling buildup that could otherwise compromise valve performance over time.
Q
Which ceramic material offers the best corrosion resistance for acid applications?
Based on the anti-corrosive performance reference table, ZrO₂ (Zirconia) and 99.9% Al₂O₃ (Alumina) along with SiC (Silicon Carbide) consistently achieve an "A" rating across most acid environments including HCl, H₂SO₄, H₃PO₄, and HNO₃, making them the top choices for highly corrosive acid media.
Q
What size range is available for this ceramic ball valve?
The single-seat ceramic ball valve is available in nominal diameters ranging from DN15 (1/2 inch) to DN200 (10 inch), covering a wide range of industrial pipeline requirements. Both GB PN10 and HG PN10 flange standards are supported.
Q
What are the key safety features of this valve?
The valve incorporates a blowout-proof stem design for enhanced operational safety in critical environments, as well as an automatic packing compensation structure that maintains sealing force over the long term. The fixed ball design further ensures stable, low-torque operation even when handling dense slurries.
