Electric vacuum butterfly valve is used as a gas medium in the dusty cold or hot air gas pipelines of ventilation and environmental protection projects in chemical, building materials, power stations, glass and other industries. It is used as a gas medium to adjust the flow or cut off. The structure is designed and manufactured, with compact structure, light weight, easy installation, small flow resistance, large flow, avoiding the influence of high temperature expansion, and easy operation. There are no connecting rods, bolts, etc., reliable operation, long service life Position installation, independent of media flow direction.
