Metal Triple Offset Butterfly Valve
A Metal Triple Offset Butterfly Valve is a high-performance valve designed with three distinct offsets: the shaft from the centerline of the disc, the shaft from the centerline of the bore, and the conical angle of the sealing surface. This geometry eliminates friction between the disc and the seat during operation, providing zero-leakage, bi-directional tight shutoff, and exceptional durability. Constructed from strong metals such as stainless steel, duplex steel, carbon steel, or alloy steel, this valve is engineered for critical applications involving high pressure, high temperature, and corrosive media where absolute reliability is required.
Key Features of Metal Triple Offset Butterfly Valve
- Triple Offset Geometry: Eliminates rubbing between disc and seat, ensuring zero leakage.
- Metal-to-Metal Seal: Provides fire-safe, bubble-tight shutoff in both flow directions.
- High Pressure & Temperature Resistance: Suitable for severe service applications.
- Low Operating Torque: Reduced friction enhances ease of operation and actuator efficiency.
- Long Service Life: Minimal wear on sealing surfaces extends operational lifespan.
- Compact & Lightweight Design: Space-saving alternative to gate and globe valves.
- Versatile Actuation: Compatible with manual, gear, pneumatic, and electric actuators.
- Corrosion & Erosion Resistant: Available with advanced coatings and robust seat materials.
