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
