Structure and operation mode
Globe valve: adopts lifting structure, through the up and down movement of the valve flap to switch or regulate the flow of media. It is suitable for high-pressure systems, because its structure is relatively simple and good sealing performance.
Butterfly valve: rotary structure, through the rotation of the butterfly plate to control the flow of media. The structure of butterfly valve is simple, easy to install and maintain, but the sealing performance is relatively weak.

Application Scenario
Globe valve: mainly used in pipelines that require strict sealing and high-pressure systems, such as hot and cold water supply and high-pressure steam pipelines.
Butterfly valve: suitable for low and medium pressure systems, especially in the need to regulate or cut off the flow of media, such as liquid and gas transport systems.

Sealing performance
Globe valves: provide better sealing performance and are suitable for demanding industrial applications.
Butterfly valve: weaker sealing performance, suitable for less stringent occasions.
