The Three Eccentric Laminate Hard Seal Flange Butterfly Valve is a durable and energy-efficient solution. Its design incorporates the principles of three-dimensional core design, ensuring optimal performance. The valve seat is crafted from laminate stainless steel with a graphite structure, offering compatibility for both hard and soft sealing, alongside precision engineering and advanced technology.

Comprising the valve body, butterfly disc, laminate seal as the valve seat, valve stem, transmission mechanism, and other key components, this product finds extensive applications in industries such as metallurgy, electric power, petroleum, chemical, air and gas handling, as well as water supply and drainage pipelines.

Triple Eccentric Butterfly Valve-Features

There are three eccentrics (offsets) in this design. The first eccentric is the deviation of the shaft from the centerline of the sealing face. The second eccentric is the deviation of the shaft from the centerline of the pipe and valve. The third eccentric is characterized by the unique included angle between the oblique taper angle of the eccentric seat and the centerline of the pipe. This configuration ensures that the seat is completely disengaged from the sealing ring throughout the entire opening and closing process. This structure not only utilizes the cam effect but also eliminates the possibility of abrasion and leakage.

Butterfly Valve Triple Offsets Structure Design Drawing

1. Elastic property of composite metal sealing ring to perform zero leakage.
2. Torque seal to ensure two-way zero leakage.
3. STL one piece hard surface seat may be adapted to many working conditions, which is featured by long service life and easy maintenance.
4. One piece cast body, face to face dimensions conforming to ISO 5752, ASME B16.10 and API 609, replacement to high performance butterfly valves and other types of valves, easy and flexible installation.
5. Intrinsically fireproof property thanks to all metal structure and leak tight performance.
6. Anti-blowout stem for high dependability, completely conforming to API 609
7. The stem of triple eccentric butterfly valve is a shaft. The stem and disc are connected by key or pin-key combination.
