This high-performance 2-Inch (DN50) Class 150 Globe Valve is engineered from premium 2205 Duplex Stainless Steel (UNS S31803 / F51). With double the yield strength of standard 316L stainless steel and superior resistance to pitting and stress corrosion cracking (High PREN), this valve is designed for the most aggressive industrial environments. Strictly conforming to BS 1873 and ASME B16.34 standards, its OS&Y bolted bonnet and precision-machined internals provide precise flow throttling and bubble-tight shut-off performance in critical offshore, chemical, and desalination applications.

🏭 Engineering Highlights:

  • Design Standard: Fully compliant with BS 1873 and ASME B16.34.
  • Body Material: 2205 Duplex / UNS S31803 (Exceptional chloride resistance).
  • Flow Control: Rising stem, OS&Y bolted bonnet for severe-duty throttling.
  • Application: Ideal for high-pressure, high-corrosion process lines (e.g., seawater, brine) where standard austenitic steel fails.
