Metal bidirectional pressure welding butterfly valve

Bi-directional pressure welding butterfly valve is a kind of equipment with precise J-shaped elastic sealing ring and three-eccentric multi-layer metal hard sealing structure. This series of butterfly valves are widely used in metallurgy, electric power, petrochemical industry, water supply and drainage and municipal construction and other industrial pipelines with medium temperature less than 425 for regulating flow rate and carrying and breaking off fluid.

The butterfly valve is a non-closed butterfly valve, which is widely used in pipelines of building materials, metallurgy, mining, electric power, etc., where the medium temperature is ≤300°C and the nominal pressure is 0.1Mpa, which is used to connect, open, close or adjust the amount of medium.
