Product overview

The electric ventilated flange butterfly valve is designed and manufactured by welding the middle line type butterfly plate with the short structure steel plate. It has the characteristics of compact structure, light weight, easy installation, small flow resistance and large circulation. The applicable temperature depends on the selection of the valve body, the valve body has no connecting rod, bolts, etc., the work is reliable, the service life is long, the installation can be multi-station, and the flow direction is not affected by the medium. Configure AC 220V,380V power supply voltage as the driving power, accept the industrial automation instrument control system output (4~20mA) voltage and current signal can control the operation. It can be applied to industrial, metallurgical, environmental protection and other pipelines for ventilation and adjustment of medium flow, mainly used in metallurgy, chemical, building materials, power stations, glass and other industries in the ventilation, environmental protection projects of dust containing cold air or hot air gas pipeline, as a gas medium flow regulation or cutting device.



Product characteristics
1, the design is novel and reasonable, the structure is unique, the operating torque is small. And easy to operate, smart switch open and close quickly.
2, according to the on-site pressure and temperature to choose the valve material to meet the normal temperature, high temperature different temperature conditions.
