The main features of the circular electric ventilation butterfly valve are:
1. The electric ventilation butterfly valve is designed and manufactured with the new structural form of welding of the center line disc plate and short structural steel plate, which avoids the influence of high temperature expansion and is easy to operate.
2. no connecting rod, bolts, reliable work, long service life.Can be multi - station installation, not affected by the flow of media.
3. can be electrically adjusted ventilation butterfly valve switch adjustment degree.(0-180 degree adjustment)
4. Novel design, reasonable structure, light weight, quick opening and closing.
5. operation torque is small, easy to operate, labor saving dexterity.
6. use suitable materials to meet the low, medium and high temperature of different media and corrosive media, etc.
Circular electric ventilation butterfly valve is composed of electric drive mechanism and valve.Electric actuator USES 220V or 380V power source as the power, drive valve circle butterfly plate in the valve body to do 90 degrees of rotation around the valve shaft, to start and close the valve, ventilation butterfly valve body is made of welding plate, simple structure.The medium is air, dust and other non-fluid media, belongs to the non-sealing butterfly valve, butterfly valve allows the leakage amount is usually less than 1%, widely used in industrial dust, high temperature flue gas pipeline.The motion process of electric ventilation butterfly valve can be controlled by stroke, torque or axial thrust.As the working characteristics and utilization rate of valve electric device depends on the type of valve, the working specification of the device and the position of the valve in the pipeline or equipment, valve electric ventilation butterfly valve device is an indispensable equipment to realize the valve program control, automatic control and remote control.
