Triple-Offset Butterfly Valve
- Design of Triple-Offset butterfly valve
First eccentricity: The valve shaft deviates from the center of the sealing surface, reducing friction during opening and closing and extending the life of the valve.
Second eccentricity: The valve shaft deviates from the center of the pipeline to achieve rapid detachment and tight sealing of the valve disc and reduce wear.
Third eccentricity: The sealing surface adopts a conical design to ensure zero leakage when the valve is closed.
- Excellent sealing performance:
The use of high-performance sealing materials ensures reliable sealing of the valve under high pressure, high temperature and corrosive media.
Low flow resistance design: The valve disc is streamlined to reduce fluid resistance and improve system efficiency.
- Quick opening and closing:
90-degree rotation can achieve full opening or full closing, which is easy to operate and responds quickly.
- Multiple drive modes:
Supports multiple drive modes such as manual, electric, and pneumatic to meet the needs of different working conditions.
- Wide range of applications
Applicable to a variety of media such as water, steam, oil, and gas.
Can be used in high temperature, high pressure, and corrosive environments with strong adaptability.
