A butterfly valve, also known as a flap valve, is a simple structure regulating valve that can be used for switch control of low-pressure pipeline media. The butterfly valve refers to a valve with a disc as the closing component (valve disc or butterfly plate) that rotates around the valve axis to achieve opening and closing.
Butterfly Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. Mainly used for cutting and throttling on pipelines. The butterfly valve opening and closing part is a disc shaped butterfly plate that rotates around its own axis within the valve body to achieve the purpose of opening, closing or adjusting.

Install of the butterfly valve
Figure 1
| Incorrect Disc opened beyond valve body face. Pipe flanges not spread sufficiently.
| Disc positioned in the almost closed position. Pipe flange spread allows sufficient room for valve. |

Figure 2 Centering and Flanging of Valve
| Disc in closed position Gaskets installed between valve and mating flanges | Correct No flange gaskets used. Disc in the “almost closed” position. |
