Triple Offset Metal Seated Butterfly Valves: Industry-Leading Reliability

Engineered with precision, our triple eccentric (triple offset) metal-seated butterfly valves redefine performance in high-pressure, high-temperature, and corrosive environments. Featuring a patented cam-effect design that eliminates friction during operation, these valves deliver zero leakage (API 598/ANSI Class VI certified) and a 20% longer service life compared to conventional alternatives.

Core Innovations:

  • 3D Offset Geometry:
    1. Radial eccentricity: Shaft offset from sealing surface.
    2. Axial eccentricity: Shaft offset from pipeline centerline.
    3. Angular eccentricity: Conical sealing profile ensures frictionless closure.
  • 100% Metal-to-Metal Seal: Eliminates dependency on medium pressure for sealing integrity.
  • Fire-Safe Design: Compliant with API 607/ISO 10497 for extreme conditions.

Key Applications

Trusted by global leaders in:
✅ LNG & Cryogenic Systems (-196°C/-321°F)
✅ Petrochemical Refining (Class 1500/PN260)
✅ Power Generation (saturated/overheated steam)
✅ Marine & Offshore Platforms (saltwater corrosion-resistant)
✅ Chemical Processing (acid/alkali media compatibility)

Competitive Advantages Driving ROI

  1. Zero-Leakage Assurance: Bidirectional sealing meets API 598/ANSI Class VI standards.
  2. Ultra-Low Torque Operation: Optimized disc/shaft ratio reduces energy costs by 15%.
  3. Frictionless Design: Immediate disc-body separation prevents wear (200,000+ cycle durability).
  4. Field-Replaceable Seals: Cut maintenance costs by 30% with on-site ring replacement.
  5. Full Material Flexibility: Choose multilayer composite or monolithic metal seals (Inconel, Stellite, 316L).
  6. Global Compliance: ASME B16.34, EN 593, ISO 5211, and API 609 certified.
