A Triple Eccentric Butterfly Valve is a high-performance industrial valve designed for critical applications requiring tight shut-off, durability, and reliable operation under extreme conditions. The "triple eccentric" design refers to the three distinct offsets in the valve's geometry, which work together to minimize wear, reduce friction, and ensure a tight seal even after prolonged use. This design makes it suitable for handling high-pressure, high-temperature, and corrosive media.

The stem axis deviates from the center of the disc and the center of the body at the same time, and the rotary axis of the valve seat and the axis of the valve body channel have a certain Angle, called the triple eccentric butterfly valve.
Three eccentric butterfly valve, is widely used in the medium temperature ≤425℃ metallurgy, electric power, petrochemical industry, as well as water supply and drainage and municipal construction and other industrial pipelines, used to adjust the flow and load the body. Material is divided into: cast iron, cast steel, stainless steel.
Key Features:
1. Triple Eccentric Design:
- First Eccentricity: The valve shaft is offset from the disc centerline.
- Second Eccentricity: The shaft is offset from the pipeline centerline.
- Third Eccentricity: The seating surface is angled, ensuring a frictionless seal during operation.
2. Bidirectional Sealing: Provides excellent sealing performance in both flow directions.
3. Metal Seat: Typically uses metal-to-metal sealing, making it suitable for high-temperature and high-pressure applications.
4. Flange Connection: Designed to fit between ANSI, DIN, or other standard flanges, ensuring easy installation and compatibility with existing systems.
5. Materials: Constructed from high-quality materials such as stainless steel, carbon steel, or special alloys for corrosion resistance and durability.
Advantages:
- Zero Leakage: The triple eccentric design ensures a bubble-tight seal, even under high pressure and temperature.
- Long Service Life: Reduced friction and wear during operation extend the valve's lifespan.
- Versatility: Suitable for a wide range of applications, including oil and gas, power generation, chemical processing, and water treatment.
- Low Maintenance: The robust design minimizes the need for frequent maintenance.
Applications:
- High-temperature steam systems.
- Oil and gas pipelines.
- Chemical and petrochemical industries.
- Power plants and water treatment facilities.
The Triple Eccentric Flange Butterfly Valve is ideal for demanding applications where reliability, durability, and tight shut-off are critical. Its innovative design and robust construction make it a preferred choice for modern industrial systems.
