95% Alumina Ceramic Water Valve Discs Ceramic Disc Valve Cartridge For Faucet Tap

95% alumina ceramic water valve discs refer to valve seals (typically valve cores, valve discs, or valve seats) made of a ceramic material with a 95% alumina (Al₂O₃) content. They typically work with a valve body made of metal or other materials, controlling fluid flow and flow through relative motion (such as rotation or sliding).

"95% pure alumina" is a key specification, signifying an optimal balance between performance and cost, making it the most cost-effective and widely used choice in industrial applications. Alumina ceramic valve discs are a critical, wear-resistant sealing component widely used in various valves, and their performance directly determines the lifespan and reliability of the valve.

95% alumina ceramic water valve discs are a revolutionary upgrade for industrial valves. Their ultra-high hardness and inherent corrosion resistance fundamentally address the core pain points of valve wear and leakage in harsh water conditions.

This is more than a simple replacement part; it's the ultimate solution for long life, high reliability, and low overall cost. When your valves frequently fail in particulate and corrosive water, upgrading their core seals to 95% alumina ceramic discs is undoubtedly the wisest and most economical choice.

Traditional metal valve discs wear rapidly in water, especially "hard water" or industrial wastewater containing tiny solid particles (silt, minerals, and scale), leading to valve leakage, loose closing, and frequent replacement. 95% alumina ceramic valve discs perfectly address these issues:

1. Extreme Wear Resistance (Core Advantage)

• Performance: With a hardness of up to HRA 85-87, its wear resistance is dozens or even hundreds of times greater than that of stainless steel.
• Value: Extremely long life in impure water, achieving the goal of "using porcelain to treat water, using hard to wear soft"—impurities cannot wear away the ceramic surface. This significantly reduces maintenance frequency and replacement costs.

2. Excellent Corrosion Resistance

• Performance: Highly resistant to most acidic and alkaline water, solvents, and chemicals, completely rust-proof.
• Value: Suitable for use in corrosive water, such as seawater, chemical processes, and wastewater treatment, with a lifespan far exceeding that of Versailles steel.

3. Low Friction & Self-Lubrication

• Performance: Precision polished to a mirror-smooth surface with a low friction coefficient. 
• Value: Valve opening and closing operations are more labor-efficient, operating smoothly and minimizing wear on the seal.

4. High Rigidity & Dimensional Stability

• Performance: High elastic modulus minimizes deformation under pressure; low thermal expansion coefficient minimizes temperature fluctuations.
• Value: Maintains precise clearances over time, ensuring reliable and consistent sealing and preventing seizures or leaks caused by deformation, thermal expansion, and contraction.

5. Excellent Cost-Effectiveness

• Performance: 95% aluminum oxide offers an ideal balance between high performance and manageable costs.
• Value: While the price per piece may be higher than that of standard metal valve discs, its exceptionally long service life minimizes overall operating costs.

95% alumina ceramic valve discs are designed to address wear and corrosion issues in demanding water conditions and are widely used in:

1. Water Treatment and Environmental Protection Industries

• Applications: Control valves, sludge discharge valves, and dosing valves in sewage treatment plants; valves in seawater desalination systems.
• Operating Conditions: Water flows containing large amounts of suspended particles, silt, and corrosive chemicals.

2. Chemical and Process Industries

• Applications: Slurry valves, circulating water valves, and corrosive media transfer valves in chemical processes.
• Operating Conditions: Strong acids, strong bases, and highly corrosive fluids.

3. Power and Metallurgy Industries

• Applications: Valves in power plant ash handling systems (fly ash, bottom ash), and blast furnace coal injection valves in the metallurgical industry.
• Operating Conditions: Harsh conditions involving high temperatures, high pressures, and the presence of hard particles.

4. General Industry and Construction

• Applications: Industrial cooling water systems, central air conditioning water systems, and valves for high-pressure cleaning equipment.
• Operating Conditions: Ordinary water contains tiny hard particles such as scale and rust, which can cause metal valve failure over time.

5. Agricultural Irrigation

• Application: Control valves for large agricultural irrigation systems.
• Operating Conditions: River water contains sediment, which can easily wear out standard valves.
