With the acceleration of the industrialization process, more and more factories have higher requirements for butterfly valve. The butterfly valve can be used in more and more areas. Because more and more factories have started to use automatic control, people hope that the butterfly valve can be operated automatically without manual operation. Therefore the electric actuator is developed, the electric actuator can control the mechanical movement of the butterfly valve through the automatic control system, thus saving more manpower and material resources. In addition, the use of electric butterfly valve can also enhance the safety of production, and even play a role in environmental protection. In some dangerous situations, the automatic electric butterfly valve can reduce the harm of this kind of working condition to the personnel.
The working principle of the electric butterfly valve is to control the switch of the valve through the power supply signal, the electric actuator butterfly valve working power supply is: AC220V, AC380V, DC24V, input signal 4-20mA 0-10v. When the power is turned on, input 220V voltage, the electric actuator begins to work, input control signal and one-way power supply can control system operation. Can also receive 4-20mA signal on the valve opening very precise control, and then achieve the media flow, pressure and other parameters of control and regulation.
The electric actuated butterfly valve starts the electric actuator through the electricity, the electric actuator drives the butterfly valve stem rotation, and the butterfly plate connecting the valve stem, will do the rotation movement around the valve stem, thus the full butterfly valve opening and closing action In this way, the flow of the medium in the pipe can be controlled or regulated.
Electric butterfly valve with other butterfly valve products, there are many categories. Electric wafer butterfly valve and electric flange butterfly valve are different according to connection mode. Electric soft seal butterfly valve and electric hard seal butterfly valve are different according to sealing surface material. According to the control of electric drive devices, there are switching electric butterfly valve, Adjustable electric butterfly valve, intelligent electric butterfly valve and explosion-proof electric butterfly valve.
