Do you really know Butterfly Valve?

1. Butterfly valve has small flow resistance when fully open. When opened between about 15° and 70°, sensitive flow control can be carried out, so in the field of large diameter regulation, butterfly valve application is very common. Because of the movement of butterfly valve plate with wipe, so most butterfly valves can be used with suspended solid particles of the medium. Depending on the strength of the seal, it can also be used in powder and granular media.

2 butterfly valve is suitable for flow regulation. Because the butterfly valve in the pipe pressure loss is relatively large, about three times the gate valve, so in the selection of butterfly valve, should fully consider the pipeline system by pressure loss, should also consider the strength of the butterfly plate under the pipeline medium pressure when closing. In addition, the operating temperature limits of resilient seat materials at high temperatures must be considered.

3 butterfly valve structure length and overall height is small, open and close faster, and has good fluid control characteristics. Butterfly valve structure principle is most suitable for the production of large diameter valves. When butterfly valve is required to control flow, the most important thing is to correctly choose the specifications and types of butterfly valve, so that it can work properly and effectively.
