Butterfly valve

The butterfly valve is also called a butterfly valve. As its name suggests, its key components are like butterflies blowing in the wind and freely swirling.

The disc of the butterfly valve is a disc that rotates around an axis in the seat. The size of the angle of rotation is the degree of opening and closing of the valve.

The butterfly valve has the characteristics of light weight, saves material compared with other valves, has a simple structure, is quick to open and close, can be used for cutting and throttling, has small fluid resistance, and is labor-saving. The butterfly valve can be made into a large diameter. Where a butterfly valve can be used, it is best not to make the gate valve, because the butterfly valve is economical and more tunable than the gate valve. At present, butterfly valves are widely used in hot water pipes.
