With the acceleration of the industrialization process, more and more factories are increasingly demanding butterfly valves, and the places where butterfly valves can be used are becoming more and more extensive. And because more and more factories are using automated controls, it is hoped that butterfly valves can be automated without manual operation. Therefore, electric actuators have been developed, and electric actuators can control the mechanical movement of the butterfly valve through an automatic control system, thus saving more manpower and material resources. In addition, the use of electric butterfly valves can also enhance the safety of production work, and even play a role in environmental protection. In some dangerous situations, automated electric butterfly valves can reduce the damage to personnel in such working conditions.
And now let’s share with you what is an electric actuator butterfly valve.
The electric butterfly valve is equipped with an electric actuator on the butterfly valve. The electric actuator is used to control the selection of the butterfly plate to achieve the purpose of controlling the butterfly valve switch.
The working principle of the electric butterfly valve is to control the switch of the valve through the power signal. The working power of the electric butterfly valve is: AC220V, AC380V, DC24V, and the input signal is 4-20mA 0-10v. When the power is turned on, input 220V voltage, the electric actuator starts to work, input control signal and one-way power supply can control the system operation. It can also receive 4-20 mA signal to control the opening degree of the valve very accurately, so as to control and adjust the parameters such as medium flow and pressure.
The electric butterfly valve starts the electric actuator by electric power, the electric actuator drives the valve stem of the butterfly valve to rotate, and the butterfly plate connects the valve stem, and rotates around the valve stem, thereby completely opening and closing the butterfly valve, thereby realizing the pair The media flow in the pipe is controlled or adjusted.
Electric butterfly valves, like other butterfly valve products, also have many classifications. According to the connection method, there are electric pair butterfly valve and electric flange butterfly valve; according to the sealing surface material, there are electric soft sealing butterfly valve and electric hard sealing butterfly valve.
According to the control form of the electric drive device, there are an on off type electric butterfly valve, an modulating type electric butterfly valve and an intelligent type electric butterfly valve.
