The disc is one of the core components of a concentric type butterfly valve, directly responsible for regulating and controlling fluid flow. Our discs are manufactured from SS316 (AISI 316 stainless steel), which is widely recognized for its excellent corrosion resistance, strength, and durability in demanding environments.
Key Features:
Material: SS316 (AISI 316 stainless steel)
Corrosion Resistance: Superior resistance against seawater, weak acids, alkalis, and chloride-containing media, making it suitable for marine, chemical, and offshore applications.
Mechanical Strength: High tensile and yield strength, ensuring reliable operation under pressure.
Surface Finish: Precision-machined and polished to reduce flow resistance and enhance sealing performance.
Application Range: Suitable for water supply, seawater desalination, chemical processing, shipbuilding, and general industrial use.
Advantages：
Long service life due to excellent wear and corrosion resistance
Ensures tight shut-off and smooth operation
Compatible with a wide range of elastomer seat materials in concentric type butterfly valves
