Uses of electric valve actuators

 1. When it comes to the use of electric valve actuators, it is actually to convert the rotary motion of the motor into the operation (linear operation/rotary operation) that you want to achieve to achieve the operation of the Electric Actuator. And it has remote control function, local control function, which can be operated electrically or manually.
    2. The basic Actuator is used to drive the valve to the fully open or fully closed position. The Actuator used to control the valve allows the valve to be brought into any position with precision. Although most actuators are used to open and close valves, today's actuators are designed to go far beyond simple switching functions, including position sensing devices, torque sensing devices, electrode protection devices, logic control devices, digital communication modules and PID control modules, all of which are housed in a compact housing.
    3. The electric valve actuator is the driving device of various electric valves in the rotary control system, which is used to control the opening and closing of the valve, and is suitable for the valves of angular stroke such as butterfly valves, ball valves and dampers, which can accurately act according to the control instructions, and is the driving device for remote control, centralized control and automatic control of the valve.
    Features of electric valve actuators:
    1. Advantages
    Electric valve actuators are small and lightweight, easy to disassemble and maintain, and can be installed in any position. The structure is simple and compact, and the 90-degree rotation opens quickly. The operating torque is small, and the effort is low and lightweight. The flow characteristics tend to be straight, and the regulation performance is good. The sealing material is age-resistant, corrosion-resistant, and can be applied to a variety of media. Electric valve actuators are widely used in water supply and drainage systems such as water plants, power plants, steel mills, papermaking, chemical industry, and catering, as a regulation and cut-off. And the energy access is convenient, the signal transmission speed is fast, the transmission distance is long, it is convenient for centralized control, the sensitivity and accuracy are high, the electric valve actuator is convenient to cooperate with the electric regulating instrument, and the installation and wiring are simple.
    2. Disadvantages
    The structure of the electric valve actuator is complex, the thrust is small, and the average failure rate is higher than that of the pneumatic valve actuator, which is suitable for places with low explosion-proof requirements and lack of air source.
