Our Zirconia Ceramic ball valve components are according to customer specifications in many formulations for solving various highly abrasive, and/or highly corrosive fluid-handling applications. They can increase the working life of process equipment wherever wear, corrosion and thermal problems shorten the life of ball valves.
Application:
Zirconia Ceramic Ball Valve Components are low-cost, long lasting, extra resistant to corrosion, high temperature, wear resistant. They can be widely used in fields like Coal; Limestone; Fly ash; Salt; Kaolin pulp; Ferric chloride; Titanium dioxide; Chromic acid chlorine;Sulfite crystals; Sludge; Acetic acid; and bromine...
More About Zirconia Ceramics:
Zirconium oxide (ZrO2 also known as zirconia) is a material with very high resistance to crack propagation. Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.Another outstanding property combination is the very low thermal conductivity and high strength.
Zirconium oxide ceramics are used among various applications, such as precision ball valve balls and seats, high density ball and pebble mill grinding media, rollers and guides for metal tube forming,hot metal extrusion dies, marine pump seals and shaft guides etc.
