Triple Eccentric Metal-Seated Butterfly Valves: Next-Gen Industrial Sealing Solutions

Discover industry-leading triple eccentric metal-seated butterfly valves for LNG, petrochemical & high-pressure applications. API-certified, zero-leakage sealing, wide temperature range (-321°F to +1202°F). Request a quote for custom solutions today!

Engineered with precision, our triple eccentric design revolutionizes valve performance:

  • 1st Eccentric: Shaft offset from sealing surface centerline
  • 2nd Eccentric: Shaft offset from pipeline axis
  • 3rd Eccentric: Scalene cone geometry

This patented design eliminates friction during 90° operation, delivers zero-leakage bidirectional sealing (API 598/ANSI Class VI), and extends service life by 300%+ in extreme conditions. Trusted by Fortune 500 clients in LNG, nuclear power, and chemical processing.

Industry-Leading Sealing Technology

Choose between multi-layer composite seals (ideal for corrosive media) or full-metal seals (for ultra-high temps/pressures).

Sealing Principle:

  • Conical geometry creates uniform metal-to-metal contact force.
  • Zero friction during operation prevents seat wear.
  • Positive release angles eliminate dead zones.
