Electric flange hard seal butterfly valve
The electric hard seal flange butterfly valve adopts a precision elastic sealing ring and a three eccentric multi-level metal hard seal structure, and is widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃ C, for regulating flow and cutting off fluids.
Performance characteristics:
1. This valve adopts a three eccentric sealing structure, with almost no wear on the valve seat and butterfly plate, and has a sealing function that becomes tighter as it is closed.
2. The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance in both low and high temperatures, corrosion resistance, and long service life.
3. The sealing surface of the butterfly plate is made of welded cobalt based hard alloy, which is wear-resistant and has a long service life.
4. This valve has a bidirectional sealing function, which is not limited by the flow direction of the medium or the spatial position during installation, and can be installed in any direction.
