Triple Eccentric Metal Seated Wafer Butterfly Valve

The triple eccentric metal seated wafer butterfly valve is a long-life, energy-saving butterfly valve newly developed by Waits. It consists of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. Its structure adopts two-dimensional or three-dimensional eccentric principle design, elastic seal or hard and soft multi-level seal compatible processing technology, which reduces the torque of the butterfly valve during operation, achieving the effect of labor saving and energy saving. At the same time, it ensures the overall reliability of the butterfly valve in terms of corrosion resistance, high temperature resistance and wear resistance.

Performance Features

1. Triple eccentric metal seated wafer butterfly valve has unique structure, small size and light weight, flexible operation, labor-saving and convenient;
2. Reliable sealing, can meet various standards;
3. Good flow characteristics and adjustable function;
4. Adopting eccentric principle, the sealing surface is close to zero wear, which prolongs the service life of the valve;
5. Wide range of applications, can be used for water, steam, oil, air and gas and other media;
6. Suitable for pipelines of different temperatures, grades, corrosion and other working conditions;
7. Triple eccentric metal seated wafer butterfly The valve body and valve seat of the valve are connected components, and the valve seat sealing surface layer is welded with heat-resistant and corrosion-resistant alloy materials;
8. Three eccentricities: the center line of the shaft deviates from the center line of the sealing surface, the center line of the shaft slightly deviates from the center line of the pipeline, and the center line of the valve body sealing surface (oblique cone) forms an angle of with the center line of the pipeline;
9. The multi-layer sealing ring is fixed on the valve plate, which has the advantages of high temperature resistance, easy operation, no friction when opening and closing, and the sealing is compensated as the torque of the transmission mechanism increases when closing, which improves the sealing performance of the butterfly valve and prolongs the service life;
10. The multi-layer sealing ring adopts soft and hard laminated metal sheets, which has the dual advantages of hard and soft sealing, and has zero leakage sealing performance regardless of low and high temperature conditions.
