The electric flanged hard-sealed butterfly valve features a precision J-shaped elastic sealing ring and a triple-offset multi-layer metal hard-sealing structure.

Widely used in industrial pipelines with a medium temperature ≤425°C in sectors such as metallurgy, power, petrochemicals, water supply/drainage, and

municipal construction, it serves to regulate flow and cut off fluids. Adopting a triple-offset design, both the valve seat and the sealing surface of the butterfly

disc are made of stainless steel with varying hardness, offering excellent corrosion resistance and a long service life. This valve also provides a bidirectional

sealing function.
