It is used in cold air or hot air gas pipelines containing dust in ventilation and environmental protection projects in chemical industry, building materials, power station, glass and other industries, as a gas medium to regulate flow or cut off devices.
The electric flange butterfly valve uses the electric actuator to input the standard signal, and the electric unit drives the gear turbine worm Angle torque to drive the disc rotation. When the valve is in the fully open position, the thickness of the disc is the only resistance when the medium flows through the valve body, so the pressure drop generated by the valve is small, so it has better flow control characteristics.
The butterfly valve is designed and manufactured by using the new structure form of welding between the middle line type butterfly plate and the short structure steel plate. It has the advantages of compact structure, light weight, easy installation, small flow resistance, large circulation, avoiding the influence of high temperature expansion and light operation. No connecting rod, bolt, etc., reliable work, long service life. Can be installed in multiple stations, not affected by the flow of media
