Aluminum oxide ceramic valve seat

Why choose alumina ceramic valve seat?
Q: Under harsh working conditions, traditional metal valve seats are prone to wear, corrosion, and leakage, leading to frequent equipment maintenance and rising costs. How can we solve this problem?
Answer: The alumina ceramic valve seat, with its ultra-high hardness, excellent corrosion resistance, and stable sealing performance, can significantly extend the valve life, reduce maintenance frequency, and solve sealing problems in high temperature, high pressure, and strongly corrosive media environments.
Q: What should be done if the valve seat is easily damaged in the face of particle media and high-speed fluid erosion?
Answer: The hardness of ceramic materials is second only to diamond, and their wear resistance far exceeds that of metals. They effectively resist particle erosion and erosion, ensuring the long-term stable operation of valves.
Q: How to achieve high-precision sealing and cost control simultaneously?
Answer: Aluminum oxide ceramic valve seats provide customized sizes and specifications, suitable for various valve designs, and achieve total cost optimization through long lifespan and low maintenance costs.

Product Overview
The alumina ceramic valve seat is made of high-purity alumina (Al ₂ O ∝, purity ≥ 95%) through precision sintering and grinding processing, which has excellent mechanical strength, high temperature resistance (up to 1600 ℃), chemical corrosion resistance, and wear resistance. Suitable for various types of valves such as ball valves, gate valves, globe valves, etc., widely used in industrial fields such as energy, chemical, metallurgical, pharmaceutical, environmental protection, etc.

Product advantages

1. Ultimate wear resistance: With a hardness of HRA85 or higher, the wear resistance is 5-10 times that of traditional metal valve seats, significantly extending the service life of the valve.
2. Strong corrosion resistance: resistant to acid, alkali, salt, and various organic solvents, suitable for corrosive media environments.
3. High temperature stability: Maintain dimensional stability in high temperature environments, without softening or deformation, suitable for high temperature and high pressure working conditions.
4. High sealing performance: With a high surface finish (Ra ≤ 0.2 μ m), it is precisely matched with the valve ball/core to achieve zero leakage sealing.
5. Energy saving and environmental protection: Low friction coefficient reduces driving energy consumption, no metal ion precipitation, and meets environmental protection requirements.
