Among all types of valves, there is a particular one with the most beautiful name—the butterfly valve. How did the name come from? In answering this question, we could use analogy. For example, the ball valve looks like a ball, so can we guess that the butterfly valve looks like a butterfly? Well, it seems a little funny, but I have to say: “Bingo, right answer!”
The butterfly valve is a regulating valve with simple structure, and it can be used for switching control of a low pressure pipeline medium. The opening and closing member (valve or disc) of the butterfly valve is a disc that rotates around the valve shaft to open and close. In the cylindrical passage of the butterfly valve body, the disc rotates about the axis to achieve flow control. The valve is fully open when the disc reaches 90°, and changing the angle of the disc can adjust the flow of the medium.
When the butterfly valve is fully open, it has a small flow resistance; when it is between about 15° and 70°, it can perform better flow control. Therefore, the butterfly valve is widely used in the field of large diameter adjustment. Most butterfly valves are available for media with suspended solid particles. Depending on the strength of the seal, it can also be used in powdered and granular media.
The butterfly valve has a small structural length and overall height, a fast opening and closing speed, and good fluid control characteristics. The structural principle of the butterfly valve is most suitable for making large diameter valves. When using the butterfly valve as a control flow, the most important thing is to correctly select the size and type of the butterfly valve so that it can work properly and efficiently. It is worth mentioning that the valves used in the medical and food fields have higher requirements in all aspects, so it is recommended to use the sanitary butterfly valve. The sanitary butterfly valve provided by Adamant Valves uses 304SS or 316 stainless steel, which is non-toxic and harmless with smooth and clean surface, and it is not easy to cause corrosion or fall off.
