The Triple Offset Multi-Layer Metal Seated Flanged Butterfly Valve is a high-performance industrial valve designed for demanding applications requiring zero leakage, high pressure, and high temperature resistance. Featuring a unique triple eccentric design, it eliminates friction between the disc and seat during operation, ensuring extended service life and bubble-tight shutoff.
Key features include:
Multi-layer metal sealing: Provides superior sealing performance with laminated stainless steel and graphite layers for bidirectional zero leakage.
Triple offset geometry: The shaft is offset from the centerline, the disc from the seat, and the conical sealing surface creates a cam-like action for frictionless opening/closing.
Flanged connection: Double flanged body compliant with ANSI/ASME standards for easy installation in pipelines.
Robust construction: Body materials in carbon steel (WCB), stainless steel (CF8M), or special alloys; suitable for temperatures from -196°C to 760°C and pressures up to ANSI Class 600.
Applications: Ideal for oil & gas, petrochemical, power generation, refining, water treatment, and severe service environments handling steam, abrasive media, or corrosive fluids.
This valve offers low torque operation, fire-safe design, and minimal maintenance, making it a reliable alternative to gate or globe valves in critical isolation and control systems.
