High Performance Multi-Level Metal Seal Butterfly Valve

The high-performance multi-layer metal-sealed butterfly valve designed by Dazhong Valve Group, this valve is designed on the basis of absorbing and digesting foreign products, using three-dimensional eccentric principle design, soft and hard laminated metal sheets such as butterfly plate sealing ring, it has elastic sealing and soft The hard multi-level seal is compatible with dual features, the valve seat and the disc sealing ring are almost free of wear, and the valve body sealing surface is made of surfacing drill-base cemented carbide.

• This butterfly valve is widely used in metallurgy, electric power, petroleum, chemical industry, building materials, urban water supply and drainage and other pipelines to control flow and cut off medium.

• This butterfly valve series is designed on the basis of absorbing and digesting foreign technology, and adopts the principle of three-dimensional eccentricity. It makes the space movement trajectory of the sealing surface ideal, and the performance of the valve is reliably guaranteed.

• Soft and hard laminated metal sheets such as butterfly plate sealing ring, it has the dual characteristics of elastic sealing and soft and hard multi-layer sealing compatibility, no matter in the case of corrosion resistance and high temperature resistance, it has good sealing performance.

• The three-dimensional eccentric structure is adopted, and the valve seat and disc sealing ring have almost no wear and tear, and have the function of tightening the tighter.

• The sealing surface of the valve body is made of surfacing drill-base cemented carbide, and the sealing surface is wear-resistant, corrosion-resistant and has a long service life.

• Unique structure, flexible operating parts, convenient and labor-saving.
