Electric 3-way regulating pneumatic valve is suitable for the environmental protection equipment

Electric control pneumatic valve is also called electric regulating pneumatic valve, is an important executive element in industrial automation process control instrument. With the improvement of industrial automation field, it is more and more widely applied in the field of all kinds of industrial production. Compared with the traditional pneumatic control valve, has obvious energy saving, environmental protection, convenient installation, etc. Electric control pneumatic valve according to the structure classification, can be divided into electric single-seat regulating pneumatic valves, electric two-seater regulating pneumatic valves, electric socket to adjust pneumatic valve, electric 3-way regulating pneumatic valve, etc. , to introduce here are often used in environmental protection equipment electric 3-way regulating pneumatic valve on the main features.





electric 3-way regulating pneumatic valve is typically used for heat exchangers of two kinds of media regulation, and the ratio of simple adjustment. It can be made of one instead of two single, two-seat regulating pneumatic valve is used, also can save pipeline installation, saving investment, occupy small space. Therefore electric 3-way regulating pneumatic valve is widely used in electric power, chemical industry, metallurgy, petroleum, light industry and environmental protection industries.





electric 3-way regulating pneumatic valve is suitable for the environmental protection equipment, mainly is concrete the following features:


1, the direction of fluid for pneumatic valve core are away, so the working stability is good.


2, in addition to guide bushing pneumatic valve cover, pneumatic valve core and pneumatic valve seat surface side also has a guiding role, the area is large, reliable work.


3, depth of the servo amplifier adopts dynamic negative feedback, can improve the precision of adjustment.


4, electric operator has a variety of forms, can be applied to 4 ~ 20 ma. DC or 1 ~ 5 v. 直流。


5, electrical power regulating pneumatic valve can be directly controlled by the current signal of pneumatic valve opening, without the servo amplifier.


6, saving investment, automation and single-seat, two-seat or sleeve, compared to adjust the pneumatic valve of the same system can save a pneumatic valve, simplify the system, save investment.


7, bellows seal type of mobile pneumatic valve stem form completely sealed, plugging fluid leakage.


8, the 3-way regulating pneumatic valve is divided into FenLiuXing and confluence type, to shunt and confluence of medium, according to the model selection of the site conditions are determined.
