Butterfly valve for pipeline pressure is also very limited.Butterfly valve in the pipeline pressure loss is three times as much as gate valve, so in the high pressure condition, it is not appropriate to choose butterfly valve. In the selection of butterfly valve, to fully consider the pressure loss by the pipeline system, but also consider the point is that when the butterfly valve is closed, whether the butterfly valve can withstand the pressure of pipeline media.
In common valve types, butterfly valve structure length and overall height are relatively small, open and close very quickly, with good fluid control performance. Butterfly valve this structure makes it in many valve types, become the most suitable for the production of large diameter valves.What is the standard of butterfly valve selection?Butterfly valve can be used if:
1. A pipe that needs to close or regulate the flow.
2. The medium is water, air, mud and other pipelines.
3. Short structural length, fast opening and closing speed and small pressure difference are required.
4. Ventilation pipe or corrosive medium pipe.
