The ventilation butterfly valve is used in the ventilation of chemical industry, building materials, power plant, glass and other industries, the dusty cold air or hot air gas pipeline of environmental protection engineering, as the gas medium to regulate the flow or cut off the pipeline control device. This kind of valve should be installed horizontally in the pipeline.In the process of field use, sudden emergency fault, in the case of external power outage, power reset series electric actuators can be immediately valve command, a program to continue to work to the fully open or close the valve state power reduction effect, power is fully open or close the factory can set according to the requirement, this greatly satisfy the demands of various special pipeline protection, its widely used in power plants, chemical plants, environmental protection equipment, etc.
