The Triple Offset Multi-Layer Metal Seated Wafer Butterfly Valve is a high-performance industrial valve designed for demanding applications requiring zero leakage, long service life, and reliable operation under high temperature and pressure conditions.
Featuring a unique triple eccentric design with multi-layer metal-to-metal sealing, this wafer-style butterfly valve eliminates friction during opening and closing, reducing seat wear and extending valve lifespan. The multi-layer sealing ring (typically stainless steel laminated with graphite) ensures bi-directional bubble-tight shutoff, fire-safe performance, and excellent resistance to corrosion, abrasion, and thermal shocks.
Ideal for industries such as oil & gas, petrochemical, power generation, chemical processing, and water treatment, it supports temperatures from cryogenic to 650°C and pressures up to ANSI Class 600 or higher. Compact wafer body design allows easy installation between flanges, saving space and weight compared to flanged valves.
Key Features:
Zero leakage bi-directional sealing (API 598 compliant)
Frictionless operation for low torque and extended cycle life
Multi-layer hard/soft compatible seal for superior durability
Suitable for severe service: high pressure, high temperature, abrasive media
Available in carbon steel, stainless steel, and special alloys
This energy-saving, long-life valve is an excellent alternative to gate, globe, or ball valves in critical isolation and control applications.
