The use of electric pneumatic control valve and maintenance

With the rapid development of our country industry, electric pneumatic control valve 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, this paper will detail the use and maintenance of electric pneumatic control valves. 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.
