What Is a Butt Weld Ball Valve?

A Butt Weld Ball Valve features weldable pipe ends that are joined by butt welding to the pipeline, creating a seamless and permanent connection. These valves are ideal for:

  • High-pressure and high-temperature lines
  • Underground or inaccessible systems
  • Steam, gas, oil, or hazardous chemical pipelines
  • Applications requiring leak-free, tamper-resistant joints

Installation Tips for Butt Weld Valves

  • Weld valves using qualified welders as per ASME B31.3/B31.8
  • Check for proper alignment before tacking/welding
  • Perform post-weld hydro testing after cooling
  • Use preheat and post-weld heat treatment where required
  • For critical lines, perform radiography or ultrasonic weld inspection
