What Is an ANSI Flanged Ball Valve?

An ANSI Flanged Ball Valve is a quarter-turn valve with flange ends manufactured per ANSI B16.5 (flange dimensions) and B16.34 (pressure-temp ratings). These valves are designed for:

  • Secure bolted pipeline connections
  • Standardized flange face-to-face compatibility
  • Reliable shut-off in oil, gas, water, chemical, and steam lines
  • Pressure handling up to Class 1500

Key Features of Our ANSI Flanged Ball Valves

  1. Flange ends per ANSI/ASME B16.5
  2. Pressure ratings: Class 150, 300, 600, 900, 1500
  3. Body materials: WCB, SS304/316, CF8M, Duplex, Alloy 20, Hastelloy
  4. Fire-safe design per API 607, anti-static, blowout-proof
  5. Available in 2-piece, 3-piece, trunnion-mounted, and metal seated designs
  6. Full port and reduced port options
  7. ISO 5211 mounting pad for electric or pneumatic actuation

ANSI Flanged Valve Installation Tips

  • Match valve pressure class with pipeline rating (e.g., Class 300 valve with Class 300 flange)
  • Use torque-sequencing while bolting for uniform sealing
  • Always verify gasket material compatibility with the media
  • Consider gear operators or actuators for sizes above 4”
  • Install drain or vent ports if required by project specs

FAQs

Only with a flange adapter or dual-standard valves. ANSI is preferred in North America and many export projects.

Yes—all our ANSI flanged valves are API 607 certified on request.

Absolutely—they come with ISO 5211 actuator mounting for both electric and pneumatic operation.

Use spiral wound gaskets with graphite/PTFE for high-pressure or high-temp sealing.
