Zirconia Ceramic Ball Valve Trim Custom Ceramic Hard Wearing Valve Trim

Zirconia ceramic valve trims refer to the use of zirconia ceramic materials (primarily Yttria Partially Stabilized Zirconia and Magnesia Partially Stabilized Zirconia) in key valve components (such as the valve plug, valve seat, and valve ball) instead of traditional metal or plastic. These trims are core components that control fluid flow and withstand wear and corrosion. Due to their superior performance, zirconia ceramic valve trims are primarily used to address valve life and reliability issues in extremely harsh operating conditions.

Zirconia ceramic valve trim is a proven solution to the three major industrial challenges of wear, corrosion, and erosion. It provides exceptionally long service life and high operational reliability while significantly reducing downtime and replacement frequency.

Zirconia ceramic, particularly yttria-stabilized zirconia, is ideal material for valve trims due to their unique combination of properties:

• Extreme hardness and wear resistance
• Excellent corrosion resistance
• High strength and toughness
• Excellent resistance to cavitation and flashing
• Low friction coefficient
• Non-magnetic and insulating

Zirconia ceramic valve trims are primarily used in extreme operating conditions characterized by both wear and corrosion:

• Petrochemical Industry: Slide and plug valves in catalytic cracking units; control and shut-off valves for pipelines transporting catalyst-containing slurries.
• Coal Chemical and Gasification: High-pressure differential valves for pulverized coal transportation and graywater and blackwater treatment systems.
• Power Industry: Discharge systems for fly ash and desulfurized gypsum slurries in thermal power plants.
• Mining and Metallurgy: Transport and control of ore slurries, tailings, and mud.
• Pharmaceutical and Food Industry: Applications requiring high cleanliness, corrosion resistance, and wear resistance.
• Water Treatment Industry: Wastewater control systems containing sand and other abrasive particles.
