❓ Frequently Asked Questions
Q What makes the ceramic disc butterfly valve different from a traditional butterfly valve?
Unlike traditional butterfly valves, the ceramic disc butterfly valve eliminates rotational wear between the disc and valve seat. The ceramic disc offers superior hardness, wear resistance, and corrosion resistance, resulting in a service life approximately 2× longer than conventional butterfly valves.
Q What are the maximum operating temperature and pressure for this valve?
The ceramic disc butterfly valve supports a maximum operating temperature of 180 °C and a maximum pressure of 1.6 MPa, making it suitable for demanding industrial environments involving high-temperature and high-pressure gas-solid particle media.
Q Which ceramic material is best suited for highly corrosive media?
ZrO₂ (Zirconia) and Al₂O₃ (Alumina) ceramics demonstrate excellent corrosion resistance (Grade A) against most acids and alkalis, including HCL, H₂SO₄, H₃PO₄, HNO₃, and NaOH. SiC also offers outstanding performance across nearly all tested media. However, ZrO₂ should be used with caution in HF environments.
Q What size range is available for the ceramic disc butterfly valve?
The valve is available in sizes ranging from DN25 to DN250, which corresponds to 1 inch to 12 inches. This wide size range makes it adaptable for various pipeline systems across different industrial applications.
Q Is the valve easy to maintain, and can the seat be replaced quickly?
Yes. The valve is pneumatic-driven with low torque requirements and lightweight accessories. The seat can be replaced rapidly without complex disassembly procedures, significantly reducing downtime and maintenance costs in production environments.
Q What industries and materials is this valve typically used for?
The ceramic disc butterfly valve is ideal for industries handling particulate and bulk solid materials. Typical applications include the control of cement, silica sand, fly ash, ceramic powder, carbon powder, precious metal powders, and battery powders — particularly where cleanliness and high sealing performance are critical.
