Product Description

Product description
I. Overview
Pneumatic flange hard seal butterfly valve series products are long-life and energy-saving butterfly valves. Its structure adopts three-dimensional eccentric principle design, and a new processing technology compatible with elastic seal and hard and soft multilayer seal makes the butterfly valve reduce its torque force and achieve the functions of saving labor and energy. Thereby ensuring the overall reliability of corrosion resistance, high temperature resistance and damage resistance. It is suitable for water treatment in food, medicine, petrochemical industry, power plant, steel mill, industrial environment protection, high-rise building, water supply and drainage pipeline as the best device for regulating flow and cutting off fluid.

II.Pneumatic flange hard seal butterfly valve-characteristics
1. Unique structure, small size, portability, flexible operation, labor saving and convenience;
2. Reliable sealing, which can achieve air sealing without leakage;
3. The flow characteristics tend to have the best linear adjustability;
4. Using the principle of triple eccentricity, the sealing surface is nearly zero damage and the service life of the valve is prolonged;
5. Wide application range. For example, it can be used in water, steam, oil, air, gas and other media;
6. It is suitable for various medium pipelines with different temperatures and pressure grades below 6.4MPa and corrosion resistance.
