Engineered for maximum reliability in corrosive and high-pressure environments, this heavy-duty 2″ Class 300 CF8M Stainless Steel Gate Valve is strictly manufactured to API 600 and ASME B16.34 standards. Featuring an Outside Screw and Yoke (OS&Y) rising stem, bolted bonnet, and a precision-machined solid wedge, it provides exceptional zero-leakage isolation. The full-bore design minimizes pressure drop, making it the ultimate heavy-duty solution for oil refineries, chemical processing, and critical industrial pipelines.

🏭 Engineering & Compliance Highlights:

  • Material Excellence: Premium CF8M (316) Stainless Steel ensures superior corrosion resistance against severe industrial media.
  • Structural Integrity: OS&Y design with a bolted bonnet guarantees safe and reliable absolute isolation under Class 300 pressure.
  • Standard Compliance: Designed, manufactured, and tested in strict accordance with API 600 and API 598.
  • Connection: Standard ASME B16.5 RF flanged ends for seamless and secure pipeline integration.
