The triple offset butterfly valve has a slanting circular shape (the third eccentricity of the so-called triple eccentricity) except that the wide rod and the valve plate have two eccentricities.
Compared with other valves, the butterfly valve has a simpler structure. It is smaller in size, lighter in weight, and has fewer components. It relies on several key components to form a butterfly valve, but it has achieved better use.
The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it should also be considered that the butterfly plate is subjected to the firmness of the pressure of the pipeline medium when it is closed.
The butterfly valve has a small flow resistance when fully opened. When the opening is between about 15° and 70°, sensitive flow control is possible, so the application of butterfly valves is very common in the field of large-diameter adjustment.
Butterfly valves and gate valves are indispensable components in fluid pipelines, and they have a very wide range of applications. There is a difference in the function of the two, but the butterfly valve and the gate valve are more different. The most difference is appearance.
