• What are the application areas of electric actuators?

    Electric actuators are mainly used in the following three major areas 1. Power Plant Typical applications are: ① Thermal Power Industry applications Fan valve bezel once inlet wind valve bezel air pre-hot air door bezel flue gas recirculation bypass windshield bezel two times inlet wind door bezel main bellows valve bezel burner adjustment rod burner Swing driver hydraulic putter driver turbine speed flue gas regulator valve vapor regulator valve ball valve and butterfly valve control sliding Door Gate ② Application…

  • Determine the control mode of the electric actuator according to the production process control requirements

    1.Switch type (open-loop control) Switch type electric actuator generally achieve the valve on or off control, the valve is either in a fully open position, or in a full-off position, such valves do not need to accurately control the media flow. In particular, it is worth mentioning that the switch type electric actuator can be divided into split structure and integrated structure because of the different structure form.This must be explained when selecting, otherwise it will often occur in the…

  • Choose the right electric actuator for your valve

    Select electric actuator according to valve type 1. The Quarter-turn Electric Actuator(angle <360 degrees) is suitable for butterfly valves, ball valves, plug valves, etc. The rotation of the output shaft of the electric actuator is less than one week, that is, less than 360 degrees, usually 90 degrees to achieve the valve opening and closing process control. Such electric actuators are divided into direct connection type and base crank type according to different installation interface modes. a) Direct connection: refers…

  • Advantages of electric valves

    Electric valve Action Force distance than ordinary valve larger, electric valve switch action speed can be adjusted, simple structure, easy maintenance, can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive medium and other types of fluid flow. The traditional pneumatic valve action process due to the buffer characteristics of the gas itself, not easy to be damaged by the jammed, but must have gas source, and its control system is…

  • Why do more and more people choose intelligent valves?

    Valve market changes, in the operational efficiency and energy consumption, the use of automatic control valve is an indispensable link, the traditional industry commonly used manual valves, pneumatic valves, in the installation cost and efficiency are less than the electric valve actuator. Industry sources said that the valve class in the industrial process, mostly used to control a variety of fluid travel and flow, such as water, oil, chemical liquids, etc., based on the parameters of temperature, pressure and flow….

  • How the valve electric actuator prevents overload?

    Valve electric Actuator is an indispensable equipment to realize valve programmable, automatic control and remote control, and its motion process can be controlled by the size of stroke, torque or axial thrust. Since the working characteristics and utilization rate of the valve electric actuator depend on the type of valve, the operating specification of the device and the position of the valve on the pipeline or equipment, it is very important to select the valve electric actuator correctly to prevent…

  • Traditional irrigation vs Intelligent irrigation

    The pain point of traditional irrigation Traditional irrigation methods are inefficient, labor costs are high irrigation effect is not intuitive, can not be monitored Low utilization of water resources and rising costs High cost and low utility rate of fully imported equipment Accurate data collection and collation is not possible. Three reasons to choose QOTO Intelligent WiFi Control valve 01 Intelligent Irrigation One-stop service We have more than 12 years of industry experience, we can provide you with professional technical…

  • Working principle and structure composition of electric valve

    Introduction to the working principle of the electric actuator: The electric valve is usually connected by an electric actuator and a valve, which becomes an electric valve after installation and commissioning. The electric valve uses electric energy as power to connect the electric actuator drive valve to realize the valve switch and adjust the action.In order to achieve the pipeline medium switch or adjustment purposes. Electric Valve drive is generally with the motor, on or off the completion of the…
