Sure Shot Dual Chamber


Sure Shot® Dual Chamber Orifice fittings fully conform to the latest AGA 3/API 14.3
stringent requirements. They require no added uncertainty and provide accurate performance over the orifice plate
beta ratio range from 0.1 to 0.75 within 0.5% flow accuracy to theoretical value.

Dual Chamber Features:

  • Two-piece body allows fast, safe inexpensive orifice plate change under pressure
  • Protected positive orifice plate seal design extends service life
  • Meets or exceeds all industry specifications (AGA3/API 14.3)
  • 2”-16” ANSI Classes 150-600. For higher ratings consult factory
  • Few moving parts, positive sealing with low maintenance
  • Unique safety lock helps to prevent accidental opening under pressure while removing the orifice plate,
    indicates proper carrier location, and provides precise plug operation positioning

Fitting Pressure Ratings:

  • ANSI Class 150 (285 PSI CWP)
  • ANSI Class 300 (740 PSI CWP)
  • ANSI Class 600 (1480 PSI CWP)
