What are the advantages of electric pneumatic - valve factory products? Electric pneumatic control valve can be according to the need of control of intelligent network control system, optimization control to realize remote monitoring. Products have many advantages, so be used in many industries, there are many, and its model and with the constant innovation of science and technology, the product has become more and more popular. Here is an introduction to the related knowledge of products: electric pneumatic regulator action principle: motor power 220 vac or 380 vac, control signal 4 ~ 20 ma, valve controller, the controller convert current signal to the Angle of the stepper motor trip signal, motor rotation, by gears, levers, or gear lever, drive the stem, straight stroke or Angle of stroke. Electric pneumatic control valve feedback: the motor running, through the gear run, valve positioning signal output by SanJieTou slide rheostat, in addition to the three thread limit signals. Warm prompt: today, electric pneumatic control valve products by using frequency is very high also, so the manufacturer of these products very much, and its performance in the development of science and technology driven, but in order to make the product update security and ease to use, not only need to select the regular manufacturers when buy, but also at the time of operation must be carried out in accordance with the instruction guidance!
