The characteristics of the dynamic balance of electric pneumatic - valve where good?

Dynamic balance of electric pneumatic control valve is an important execution unit in industrial automation process control instrument. 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: energy saving, Only electricity when at work) , environmental protection, No carbon emissions) , quick and convenient installation. Features: 1, the direction of fluid on the valve core are away, so the working stability is good. 2, in addition to guide sleeve valve cover, valve core and valve seat surface side also has a guiding role, the area is large, reliable work. 3, the 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 0 ~ 10 ma. 直流。 5, electrical power pneumatic control valve can be directly controlled by the current signal valve opening, without the servo amplifier. 6, save investment automation, compared with the single-seat, two-seat or pneumatic control valve sleeve, can save a valve of the same system, simplify the system, save investment. 7, bellows seal type of mobile stem form completely sealed, plugging fluid leakage. 8, tee pneumatic regulator is divided into T and L, to shunt and confluence of medium, according to the model selection of the site conditions are determined.
