Gas butterfly valve USES the same material as the valve body to process into the sealing ring, using electric or pneumatic transmission. Its applicable temperature is determined with the selection of valve body materials, nominal pressure ≤ 0.6mpa, generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation to regulate the flow of media. Its main features are:

1. Novel design, reasonable, unique structure, light weight, quick opening and closing.

2, small operating torque, easy to operate, labor saving dexterity.

3, the use of suitable materials to meet the low, medium, high temperature of different media and corrosive media.
