Next-Gen Triple Eccentric Butterfly Valves: Zero Leakage, Maximum Durability

Engineered for critical industrial applications, our triple offset metal seated butterfly valves deliver unmatched performance in high-pressure, high-temperature, and corrosive environments. Designed to meet API 609, ASME B16.34, and ISO 10497 fire-safe standards, these valves ensure zero leakage and 30+ years of reliable operation across industries like LNG, oil refining, and power generation.

Core Advantages Driving Industry Leadership

  1. Zero Leakage Guarantee
    • API 598 & ANSI/FCI 70-2 Class VI Certified for bi-directional sealing under extreme pressures (up to PN260/Class 1500).
  2. Frictionless Design
    • Triple eccentric geometry eliminates seat-disc contact during operation, reducing wear by 90% and extending lifespan.
  3. Ultra-Low Maintenance
    • Replaceable metal sealing rings and interchangeable parts enable on-site repairs, slashing downtime and costs.
  4. Fire-Safe & Corrosion-Resistant
    • BS EN ISO 10497/API 607 certified with full-metal or multi-layered sealing options for cryogenic (-321°F) to ultra-high temperatures (1202°F).
  5. Optimized Flow Efficiency
    • High Cv/Kv coefficients minimize pressure loss, ideal for LNG transport, steam systems, and marine platforms.
