Pneumatic flange type hard seal butterfly valve

Pneumatic flange type hard seal butterfly valve series products are long life, energy saving butterfly valve. Its structured opts 3D eccentric principle design, and the valve seat adopts a multi-layer structure compatible with hard and soft seal, which is exquisite in processing and advanced in technology. This product is composed of valve body, butterfly disc, multi-layers valve seat, valve stem,transmission mechanism and other main components.

Because the butterfly valve adopts the tri-dimensional eccentricity principle design,the space movement track of the sealing surface is idealized, the sealing surface has no friction and no interference with each other, and the sealing material is selected properly, so that the sealing property, corrosion resistance, high temperature resistance and wear resistance of the butterfly valve are guaranteed reliably. Its main features are as follows:

• The opening moment is small, flexible and convenient, and labor-saving and energy-saving are realized.
• The tri-dimensional structure makes the more closing gets more sealing, the sealing performance of the butterfly disc is reliable, and no leakage is achieved.
• High pressure, corrosion resistance, wear resistance, long service life, etc.

The pneumatic flange type hard seal butterfly valve is widely used in the pipelines of the corrosive media such as metallurgy, electric power, petroleum, chemical industry, air, gas, combustible gas and water supply and drainage.
