Metal bidirectional pressure welding butterfly valve
Metal bidirectional pressure welding butterfly valve
Bi-directional butt weld butterfly valve is a kind of equipment with three-eccentric multi-layer metal (SS304+graphite)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 200 ℃ for regulating flow rate and carrying and breaking off fluid.
