  • Problems to be aware of when purchasing imported electric actuators

    1. Drive energy The most commonly used electric actuator drive energy source is a power source or a fluid source. If the power source is selected as the drive energy source, a three-phase power source is generally selected for a large-sized valve, and a single-phase power source can be selected for a small-size valve. General electric actuators are available in a variety of power types. Sometimes DC power can be selected, and the battery can be safely operated by installing…

  • What are the valves that are often seen and used in daily life?

    Valves are rarely noticed, but they play a vital role in our daily lives, operating the valve each time a faucet or gas stove is turned on, or when a water heater is used. An electric valve that helps maintain our quality of life by controlling all types of flow. They are critical to our home and almost all manufacturing processes as well as every industrial equipment and system. Different uses (on/off, control), different fluids (liquid or gas, flammable, toxic…

  • Three maintenance methods for valve electric actuators

    Valve electric devices, like the electrical equipment used in our daily life, must also be cleaned and maintained to achieve longevity. Our staff must ensure that the equipment is in a state of cleanliness, good lubrication, complete valve parts and normal operation. The following are some of the maintenance methods introduced: 1. Lubrication of valve electric actuator: trapezoidal thread of valve electric device, sliding part of stem nut and bracket, bearing part, meshing part of gear and worm wheel, worm…

  • What are the advantages of electric control valves?

    1. Good adjustment function The adjustment function is one of the main functions of the regulating valve</a>, which is characterized by 1 flow characteristic; 2 adjustable ratio R; 3 small opening working performance; 4 flow coefficient; 5 adjusting speed. The full-function ultra-light regulating valve R=100 makes the small opening degree adjustable; the Kv value is large, which is 2 to 3 times that of the single double seat valve and the sleeve valve. 2. Cut off function is good The…

  • Valve electric actuator selection basis

    Valve electric actuators refer to machines that use electrical energy as the main source of energy to drive valves. Today, I would like to tell you the five choices for valve electric actuators: One. Output speed: The opening and closing speed of the valve is fast, which is easy to produce water hammer. Therefore, the appropriate opening and closing speed should be selected according to different conditions of use. Two. Number of rotations of the output shaft: The number of…

  • Electric actuator application analysis

    Electric actuators, also known as electric actuators. It is a drive that provides linear or rotational motion that uses some kind of drive energy and works with some kind of control signal. The utility model has the advantages that the energy is convenient to use, the signal transmission speed is fast, the transmission distance is long, the centralized control is convenient, the sensitivity and the precision are high, the electric adjustment instrument is convenient to cooperate, and the installation wiring…

  • How is the electric actuator installed and commissioned?

    People in industrial production have an understanding of electric actuators. It is the terminal equipment for measurement and control in the production of enterprises. After the frequency screen input signal is displayed, the control signal is automatically converted into a parameter displacement guiding mechanism, and the motion is performed according to a certain displacement after the analysis. Electric actuators are divided into two categories according to different control methods: proportional and integral. The basic principle of the product is the…
