The application range of the electric pneumatic control valve

Electric pneumatic control valve is an important execution units in industrial automation process control instrumentation. As in the field of industrial automation degree is higher and higher, is being more and more application in the field of all kinds of industrial production. Compared with traditional pneumatic pneumatic - valve has obvious advantages: electric pneumatic regulator can ( Only electricity when at work) , environmental protection, No carbon emissions) Fast installation, convenient, No need for complicated pneumatic pipe and pump stations) 。 Electric pneumatic control valve applied scope with the rapid development of China's industrial, electric pneumatic regulator in more and more widely applied in the field of metallurgy, petrochemical, its stability, reliability, also is more and more important, its working state is good or bad will directly affect the automatic control process. Electronic single-seat pneumatic control valve, is made up of straight travel all electronic electric actuators and top guide through low flow resistance of single seat valve. With compact structure, light weight, action quick, fluid channels in an s-shaped streamlined, small pressure drop loss, large capacity of valve, precise flow characteristic, directly to adjust the instrument input ( 4 - 20mA DC 0- 10 ma DC or 1 - 5 v直流) And control signals, such as single phase power can control operation, realize the process of the pipeline automatic adjustment control, are widely used in the precise control of gas, liquid and steam medium parameters such as pressure, flow, parameters such as temperature, liquid level in a given value.
