High Performance Elastic Metal Hard Sealing Butterfly Valve

The high-performance elastic metal hard-sealed butterfly valve designed by Dazhong Valve Group. This valve is designed on the basis of absorbing and digesting foreign products, and adopts the principle of three-dimensional eccentricity. The sealing ring of this valve adopts a unique design of asymmetric arc surface. The butterfly plate sealing ring is in contact with the elastic valve seat. When the valve is opened, the butterfly plate can be quickly separated from the valve seat. The elastic sealing surface is made of high-quality stainless steel.

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

• This valve is a product modified in product performance and structure on the basis of absorbing and digesting foreign products. It is designed with three-dimensional eccentricity principle, so that the sealing pair can be organically combined, and it has high temperature resistance, Corrosion resistance, wear resistance and other advantages.

• The valve is simple in structure, compact, light in weight and easy to maintain. The valve sealing ring adopts a unique design of asymmetric arc surface. When the valve is closed, the disc sealing ring is in contact with the elastic valve seat, and the more the disc is closed, the more The tighter the seal is achieved.

• When the valve is opened, the disc can be quickly separated from the valve seat, thereby preventing the wear of the sealing surface and prolonging the service life.

• The elastic sealing surface is made of high-quality stainless steel and has good elasticity and hardness after special heat treatment.
