The electric flanged triple eccentric multi-layer metal hard-seal butterfly valve is widely used in industrial pipelines with medium temperatures ≤425°C, such as in metallurgy, power, petroleum, chemical, water supply and drainage, and municipal construction, for regulating flow and cutting off fluids.
The electric flanged triple eccentric multi-layer metal hard-seal butterfly valve is widely used in industrial pipelines with medium temperatures ≤425°C, such as in metallurgy, power, petroleum, chemical, water supply and drainage, and municipal construction, for regulating flow and cutting off fluids. This valve adopts a triple eccentric structure, with both the valve seat and butterfly plate sealing surfaces made of cast steel and stainless steel, providing excellent corrosion resistance. It is characterized by easy operation, good sealing performance, long service life, and convenient installation.
