zirconia ceramic lined valve components will allow you to extend your valve component service life. Enabling you to improve operating efficiencies, reduce maintenance costs, and minimize downtime with less frequent valve repairs. Our zirconia is extremely strong, has superior toughness, and excellent abrasion resistant. Additionally we use a proprietary manufacturing process, starting with the highest purity raw materials that result in a chemically superior zirconia product as compared to the competition. This translates into superior chemical stability of the ceramic trim components in operation when subject to the corrosive liquids and slurries in applications like: lime slurries, sodium hydroxide and acids like hydrochloric, nitric and sulfuric.

Additional structural zirconia ceramic components produced by Refractron include:

valve pump liners sleeves pistons precision ceramic balls spools press tooling extrusion tooling and wear plates



Anti-high temperature








Low-expansion coefficient

Good-self lubrication
