API Flange Gate Valve

The API Flange Gate Valve is a robust and reliable valve designed for industrial applications requiring efficient flow control and tight shut-off. Manufactured in compliance with API standards (API 600, API 602, or API 603), this valve is widely used in oil and gas, petrochemical, power generation, and water treatment industries. The flanged ends ensure easy installation and maintenance, making it a preferred choice for high-pressure and high-temperature applications.
  • Material: Carbon steel, stainless steel, alloy steel, or other materials as per ASTM standards.
  • Design: Bolted bonnet, pressure seal, or welded bonnet options.
  • Operation: Handwheel, gear-operated, or actuated for high-torque applications.
  • Seat and Disc: Metal-to-metal or resilient seating for tight shut-off.
  • End Connections: Flanged (ASME B16.5 or B16.47).
  • Standards: API 600, API 602, API 603, ASME B16.34, ANSI B16.10.
  • Applications: Oil and gas pipelines, refineries, power plants, and more.
