■ Introduction:
A zirconia ceramic ball valve is a type of valve made of zirconia ceramic. Zirconia ceramic is a high-performance ceramic material that has excellent mechanical and chemical properties. Zirconia ceramic ball valve is known for its high strength, toughness, and resistance to wear and corrosion. Zirconia ceramic valves are commonly used in applications that require high-temperature and high-pressure resistance, such as in chemical plants, refineries, and power plants. Zirconia ceramic ball valves are also used in medical applications, such as in artificial heart valves. Zirconia ceramic valves offer superior durability, reliability, and performance compared to traditional metal valves. They are also more resistant to erosion and cavitation, making them ideal for use in harsh environments. Duratec is in the position to supply zirconia ceramic ball valves, zirconia ceramic butterfly valves , zirconia ceramic globe valves , zirconia ceramic sliding gate valves,zirconia ceramic rotary valves and zirconia ceramic linear control valves.
