No matter what the butterfly valve development trend is, it is an unchangeable fact that the butterfly valves are highly valuable to a lot of industries, the auto field in particular. The butterfly valve development trend can be derived from a family of valves that when the handle is turned at a certain angle, the valve can be opened or closed from the inside out. As a matter of pneumatic actuators, the major part of a butterfly valve is the metal disc or the butterfly that is mounted on a electric actuators rod so that when the butterfly valve is closed, the disc is capable of blocking the passageway in no time while when the butterfly valve is opened, the disc can move a quarter and allows the passageway to be opened as well. Thus, although butterfly valve development trend may vary from time to time, fluids or air can always pass through the butterfly valve and the position of the disc is affected by the exterior side of the electric actuators valve. In addition, advanced fuzzy data quantification methods that are developed in recent years are in general combined to establish the butterfly valve development trend and the choice of the butterfly valve can be characterized in detail. At the same time, the information will be reserved in the evaluation database in order to improve the accuracy of the electric actuators.
On the other hand, butterfly valves are widely used in the electric actuators and pneumatic actuators so as to satisfy the actual working requirements, which are especially true when we select transport work piece that is used in the automatic line in a manufacture factory. For instance, when the work piece on the horizontal is more than five kilograms and that on the vertical is over three kilograms, the working stroke can be reduced to less than forty millimeters and the electric actuators reciprocating frequency can reach as many as twenty times per minute. What is more, according to the working condition of electric actuators, different mechanical properties can be obtained and compared from the sample books as well as the experts’ working experience and mechanics knowledge in spite of the butterfly valve development trend. And the second electric actuators relation matrixes of the electric actuators can be listed and the grade can be ranked in a similar way with the pneumatic actuator. Thus, with the detailed data of the electric actuators, its comprehensive performance has been proved to be better than that of the pneumatic actuator in a number of working conditions so we can choose out a better model via the performance analysis method that is verified in the actual application.
