Duplex Needle Valves are made from duplex stainless steel, which features a balanced microstructure of austenite and ferrite. This unique blend offers greater strength and enhanced corrosion resistance compared to standard stainless steels. The material is highly resistant to stress corrosion cracking, pitting, and crevice corrosion. On a mechanical level, Duplex Needle Valves showcase high tensile strength, good impact resistance, and exceptional pressure-handling capabilities. These characteristics enable the valves to function reliably even under extreme temperatures and pressures while ensuring precise flow control and structural integrity.
