Valve Disc Machining

This premium Stainless Steel Butterfly Valve Disc (available in 1.4408 austenitic, as well as 1.4462 and 1.4469 duplex/super duplex grades) is engineered to meet varying levels of corrosion resistance and pressure demands across diverse industries. Featuring a precision-machined and polished streamlined surface, it effectively minimizes flow resistance, prevents medium buildup, and pairs seamlessly with EPDM, NBR, and PTFE seats. Whether applied in generally corrosive environments like food and pharma (1.4408), high-chlorine marine and petrochemical scenarios (1.4462), or extreme acid and high-pressure conditions (1.4469), this disc series guarantees exceptional structural strength and long-lasting, leak-proof performance.

This premium Stainless Steel Valve Disc is a core component for concentric butterfly valves. Available in CF8 (304), CF8M (316), CF3 (304L), and CF3M (316L), it offers an excellent balance of corrosion resistance, structural strength, and cost-effectiveness. The precision-polished, streamlined surface significantly minimizes flow resistance and prevents medium buildup. Capable of operating in a wide temperature range from cryogenic up to 450°C, it is widely utilized in water treatment, HVAC, chemical processing, and shipbuilding industries to fulfill various corrosion-resistance and weldability requirements.

This high-performance Aluminum Bronze Butterfly Valve Disc (available in C95400 and C95800) is specifically engineered for severe marine and highly corrosive fluid environments. The aluminum bronze material delivers exceptional resistance to seawater corrosion, pitting, and dezincification, while maintaining outstanding mechanical strength and impact resistance. Its precision-machined, streamlined profile minimizes flow resistance and ensures a perfect, zero-leakage seal when paired with elastomeric soft seats like EPDM, NBR, or Viton. It is an ideal core component for ballast water systems, desalination plants, fire-fighting networks, and industrial cooling systems handling high-salinity media.
