What is the relationship between electric actuators and electric regulating shutters? Is it the same or who includes who?
Electric actuators are one type of actuators, but also pneumatic actuators, hydraulic actuators, and actuators, while shutter valves are a type of valve, and butterfly valves and the like. Electric actuators also include adjustable, switch-type, and mediation-type, which can control the opening degree through 4 ~ 20MA signal, and switch-type is to directly control the switch. The electric regulating louver valve is used to adjust the louver valve through an electric actuator, which can control the opening degree.
What is the difference between the electric device of the flue damper and the electric actuator?
Air door ~~ A wind door like a blind? The kind of door torque is small, there are specialized damper actuators, there are many automatic controls in buildings, Siemens and others do it, and the price is cheap. You can Baidu damper actuators, electric actuators are similar to butterfly valve ball valves on the pipeline anyway. The electric device equipped with the valve provides a self-control function. Of course, this can only be said briefly, and the specific one or two sentences are unclear.
How to choose electric actuator according to valve?
Selection of electric actuator products
Electric actuator, also known as electric actuator, electric head. In pipeline engineering, when the selected valve is determined, the optional electric actuator is one of the guarantee conditions to ensure the safe and normal operation of the electric valve. If the electric actuator is not selected properly, it will not only affect the use, but also bring serious adverse consequences and economic losses.
Generally, the following aspects can be considered to choose electric actuators:
working environment
The electric actuator is suitable for the following typical working environments.
a. Outdoor outdoor installation, wind, sand, rain, snow, frost, sunlight, large temperature difference between day and night, dust and other environments. Of course, indoor installation is more applicable.
b. Humid and dry tropical environment. Ambient temperature: -30 ℃ ～ 60 ℃.
c. Salt spray, mold, and humid working environment, such as docks, ocean or river vessels.
d. Working environment containing corrosive gases, such as chemical plants.
e. Places with severe vibration, such as steam pipes and ships.
