Principles of Ceramic Valve Design

  • The durability of the valve seat is crucial to the integrity of the entire valve.
  • Minimize possible leak points by minimizing the size of irregular valve packings.
  • Retain the media in the pipeline system.

Why Ceramic Valves?

  • Ceramic materials are 6-8 times harder than stainless steels.
  • The thickness of SKYCERA's ceramic material is often measured in inches, typically 1/4" and thicker. Most hard coatings are measured in microns. For example, Hard Chrome coatings are typically less than one-thousandth (0.001") of an inch.
  • Extreme hardness and high temperature capabilities give ceramics exceptional resistance to cavitation, even continuous, aggressive cavitation does not affect the material.
  • With special ball and seat processing, near bubble-tight shutoff can be achieved.


  • Partially Stabilized Zirconia (PSZ)
  • Tetragonal Zirconia Polycrystal (TZP)
  • Zirconia Toughened Aluminia (ZTA)
  • Tungsten Carbide Coatings and Solid Structure (WC)
