Frequently Asked Questions (FAQ)
What is the maximum sealing class of the single-seat ceramic ball valve?
The single-seat ceramic ball valve achieves a high sealing level up to ANSI Class VI, guaranteeing tight shut-off and completely leak-free performance even under demanding process conditions.
What types of media is the 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, scaling slurries, mineral slurries, and corrosive chemical media.
How does the scraper-type valve seat work and why is it important?
The scraper-type valve seat automatically cleans the sealing surfaces during every open/close operation. This self-cleaning mechanism prevents crystallization and scaling build-up on the seating surfaces, ensuring consistent sealing performance and extending the valve's service life.
What ceramic materials are available and how do they compare to steel?
Available ceramic materials include Y-ZrO₂ (Y-TZP), Mg-ZrO₂ (M-PSZ), 90/95/99 Al₂O₃, Si₃N₄, and SiC. Compared to 45# steel, these ceramics offer significantly higher hardness (up to HRA 94 vs. HRA 36), superior corrosion resistance, much lower water absorption, and excellent performance at elevated temperatures up to 1500°C.
What nominal diameter range is available for this ceramic ball valve?
The ceramic ball valve is available in nominal diameters ranging from DN15 (1/2") up to DN250 (10"), covering a wide range of industrial pipeline sizes and flow requirements.
What ball core types are available and how do they affect flow control?
Four ball core types are available: O-type (full bore, highest Cv), V60°, V45°, and V30° (progressively reduced flow). The V-notch cores provide precise throttling and flow regulation capabilities, while the O-type core is ideal for on/off isolation applications. Selection depends on the required flow coefficient (Cv) and control accuracy for your specific process.
