• 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…

  • 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…

  • 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…

  • What should you watch out for when selecting a valve electric device?

    At present, the distribution of the valve market is mainly based on the construction of engineering projects. The largest users of valves are petrochemical industry, power sector, metallurgical department, chemical industry and urban construction department. The petrochemical industry mainly uses API standard gate valves, globe valves and check valves; the power sector mainly uses high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations and some low-pressure butterfly valves and gate valves for water supply and…
