Butterfly valve
Butterfly valve is the substitution of traditional gate valve, which using the microscale deformation made by the stretch gate, to get a better sealing, the advantages of the soft seal gate valve include light&handy conduction, sealing more reliable, stretchable, and long service lift, etc. Soft seal gate valve can be used in field of tap water, waste water, construction, oil, chemical, food, medicine, light textile, electrical, boats, metallurgy, energy system, etc, such fluid line-pipe, using as the equipments to make adjust and closure.
