Product Introduction of Silicon Carbide Ceramic Sealed Ball Valves:
Silicon carbide ceramic sealed ball valves are industrial valves manufactured using high-purity silicon carbide (SiC) material, belonging to the category of hard-sealed ball valves. Their core structural features include:
1. Material Characteristics: Made from silicon carbide material with a purity of ≥99%, formed by ultra-high temperature vacuum sintering above 2200℃, resulting in a dense and defect-free microstructure.
2. Precision Machining: Through precision machining techniques such as surface grinding, cylindrical grinding, and spherical lapping, the surface roughness is reduced to as low as 0.1 micrometers, ensuring high-precision fitting between the valve seat and the ball core.
3. Sealing Structure: Adopts a double sealing ring design and a buffer compensation elastic gasket to achieve zero-leakage sealing.
