Our electric explosion-proof butterfly valves are composed of a three eccentric butterfly valve and an imported electric actuator. The structural forms include three eccentric and single eccentric structures, with sealing options of metal and soft sealing. The connection types are flanged and clamped. Below 150 degrees Celsius, a PTFE-sealed butterfly valve can be selected, while for high-temperature conditions, a three eccentric hard-sealed body valve is suitable. Explosion-proof electric regulating butterfly valves are widely used in automatic control systems of industrial processes in industries such as food, environmental protection, light industry, petrochemicals, educational equipment, papermaking, and electricity. These valves serve as regulating flow and shutoff media in water supply and drainage, gas pipelines in food, chemicals, petrochemicals, electricity, light industry, and papermaking industries.
