The characteristics and differences of ball valve and butterfly valve

The characteristics and differences of ball valve and butterfly valve
The valve whose opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve is called a ball valve. It should generally be installed horizontally in the pipeline. It is evolved from the plug valve.

The characteristics and differences of ball valve and butterfly valve

1. Low flow resistance;
2,Can be opened and closed quickly;

3.Its sealing structure determines its comparative design and corrosiveness;

4.Under higher pressure and higher temperature, complete sealing can be achieved;

5. The valve body is symmetrical, which can effectively withstand pipeline pressure and cope with high pressure conditions;
Butterfly valve is a kind of regulating valve with simple structure. It is also called flap valve. Butterfly valve that can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc and rotates around the valve shaft to achieve opening. A valve with closing.
The characteristics and differences of ball valve and butterfly valve
1,Can be used for large diameter valves;

2. Small flow resistance coefficient, quick opening and closing;
3.Simple structure, small size and easy installation;

4. It can be applied to different sealing surfaces and used in various environments, including powdery, granular media, etc.;

Ball and butterfly valves are very common and common valves. In some cases, it can be used in general, and in some cases, only one of them can be used. The difference between the two is mainly in the structure and switching principle.
When it is used to adjust the flow, the adjustment range of the butterfly valve is not large, while the V-type adjustment ball valve has accurate adjustment; in the high-pressure pipeline, the ball valve has an advantage over the butterfly valve.Compared with the ball valve, the butterfly valve has a slightly poorer sealing performance, but among the large-diameter valves, the butterfly valve has unique advantages over the ball valve, and the structure is relatively simple.
