更新時間:2018.07.20
What are the characteristics of pneumatic ventilation butterfly valves
1. Novel design, reasonable design, unique structure, light weight, quick opening and closing.
2. Small operating torque, convenient operation, energy saving and dexterity.
3. Suitable materials are used to meet the temperature and corrosive medium of low, medium and high media.
Features of pneumatic ventilation butterfly valve:
1. Designed and manufactured in the new structural form of welding of medium-wire plate and short structure plate, with compact structure, light weight, easy installation, small flow resistance and large flux, avoiding the influence of high temperature expansion and easy operation.
2. No connecting rods, bolts, etc.; reliable operation and long service life. Can be multi-station installation, not affected by the flow of media
Pneumatic butterfly valves are made of the same material as the valve body into a sealing ring, using electric or pneumatic transmission. The applicable temperature depends on the material selection of valve body, nominal pressure ~<0. 6MPa, generally applicable to industrial, metallurgical, environmental protection and other pipelines for ventilation and adjustment of medium flow. Its main features are:
1. Novel design, reasonable design, unique structure, light weight, quick opening and closing.
2. Small operating torque, convenient operation, energy saving and dexterity.
