Brief introduction of structure and performance

This product is composed of valve body, butterfly plate, sealing ring, transmission mechanism and other main components. The structure of the butterfly valve is designed based on three-dimensional eccentricity principle, and a new processing technology compatible with elastic seal and hard-soft multi-layer seal is adopted to reduce the torque of the butterfly valve in operation and achieve the functions of labor-saving and energy-saving. So as to ensure the overall corrosion resistance, high temperature resistance, anti-wear reliability.

Performance characteristics

1. Unique structure, small and portable, flexible operation, labor-saving and convenient;

2. Reliable seal, no leakage of gas seal can be achieved.

3. Flow characteristics tend to have the best linear regulation.

4. Using the principle of tri-eccentricity, the sealing surface is nearly zero and the service life of the valve is prolonged.

5. Wide range of applications. Such as: can be used in water, steam, oil, air, gas and other media.

6. Suitable for pipelines with different temperatures, pressure levels below 6.4 MPa, corrosion resistance and other media.

Purpose

The butterfly valve is suitable for adjusting flow and cutting off fluid in food, medicine, petrochemical, power plant, steel plant, industrial environmental water treatment and high-rise buildings, water supply and drainage pipelines.
