The electric ventilation butterfly valve is designed and manufactured with a new type of structure in which the midline type disc plate is welded to the short structure steel plate, avoiding the influence of high temperature expansion and being light in operation, there is no connecting rod, bolts, etc. It can be installed in multiple stations without being affected by the flow of media. The design is new, reasonable, unique structure, light weight, rapid opening and closing. It uses adapted materials to meet the low, medium and high temperature of different media and corrosive media.
It is mainly used in the dusty cold air or hot air gas pipelines for ventilation, environmental protection in industries like metallurgy, chemical industry, building materials, power stations, glass and other industries, and is used as a gas medium to regulate flow or cut off devices.
- It is designed and manufactured with a new type of structure welded with a midline plate and a short structure steel plate. It has a compact structure, lightweight, large circulation, avoids the influence of high-temperature expansion, and is easy to operate.
- Long service life, can be installed in multiple stations, and is not affected by the media flow.
- It is a kind of non-sealed butterfly valve and is widely used in pipelines with medium temperature ≤300°C nominal pressure 0.1Mpa.
- It is processed into a seal ring with the same material as the valve body and is electrically or pneumatically driven. Its applicable temperature depends on the valve body selection, nominal pressure ≤ 0.6MPa.
- The design is novel, reasonable, unique structure, light weight, rapid opening and closing.
- Small operating torque, easy operation, and dexterity.
- Use of adapted materials to meet the low, medium and high temperature of different media and corrosive media.
- Gear type double piston, large output torque, and small size.
- Use of aluminum alloy cylinder material, light weight, good appearance.
- Manual operation mechanism can be installed at the top and bottom.
- Actuators can provide feedback indications and various accessories for automatic operation.
- IS05211 standard connection provides convenience for installation and replacement of products.
- Two-point adjusting screw allows the standard product to have an adjustable range of ±4° at 0° and 90°, which ensure synchronization accuracy with the valve.
