• 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…

  • Three-way electric valve selection method?

    Electric three-type regulator valve selection basis: First, according to the pipeline parameters to choose the electric two-way regulator valve: diameter Specifications (that is, DN), interface mode 1, according to the field pipeline diameter size or flow requirements to determine the diameter (DN) size. 2, interface mode, General >DN50 to choose Flange Interface, ≤DN50 can be freely selected according to user needs. Second, according to the fluid parameters to choose the electric two-way regulator valve: material, temperature group 1, corrosive fluid:…

  • Fault and treatment method of electric regulator valve

         The working performance of the electric regulator valve will directly affect the working quality of the whole regulation system. Because the electric regulating valve is in direct contact with the tuned medium in the field, the working environment is very bad, so it is easy to produce all kinds of faults. In addition to troubleshooting these faults at any time during the production process, regular maintenance and regular repairs are required. Especially for the use of the environment…

  • Features of explosion-proof electric valve electric device

    Valve using tight seal or valve pressure, valve cover seal washer structure, trustworthy, safe and reliable. The valve adopts an intermediate double plate universal top structure, which automatically adjusts the fit between the valve and the seat sealing surface to ensure that the valve is sealed, while this structure is easy to maintain, saves cost and better valve interchangeability. Seat sealing surface spraying tungsten carbide, by the plasma formation of cobalt chromium alloy, sealing surface hardness is high, wear-resistant, wear-resistant,…
