Frequently Asked Questions (FAQ)
What are the primary benefits of the no-cavity design in ceramic ball valves?
The no-cavity design prevents medium accumulation, clogging, and scaling inside the valve body, ensuring a smooth flow path and reliable shut-off even when handling highly viscous or particulate-laden slurries.
How does the scraper-type valve seat function?
The scraper-type valve seat automatically cleans the sealing surfaces of the ball during every opening and closing cycle. This prevents crystallization, scaling, and particulate buildup from damaging the seals.
What types of media are these single-seat ceramic ball valves designed for?
They are designed for isolating and regulating various abrasive slurries, gas-solid particulate media, and gas-solid-liquid three-phase media, especially in high-wear, high-corrosion, or scaling conditions.
Which ceramic materials are available for different application environments?
Common structural ceramics include Y-ZrO₂ (Y-TZP), Mg-ZrO₂ (M-PSZ), various grades of Al₂O₃ (90%, 95%, 99%), Si₃N₄, and SiC, each offering unique density, hardness, thermal shock resistance, and temperature limits up to 1500°C.
Are these ceramic ball valves suitable for highly corrosive acids and alkalis?
Yes. As shown in the anti-corrosive performance table, materials like ZrO₂, Al₂O₃, and SiC exhibit excellent resistance (Class A) to highly corrosive media such as HCL, H₂SO₄, HNO₃, and NaOH under specified temperatures.
How does the valve maintain its sealing force over long-term operation?
The valve incorporates an automatic packing compensation structure that maintains a constant sealing force over time, compensating for wear and significantly extending the service life of the valve stem packing.
