The electric ventilation butterfly valve is mainly used in the dusty cold air or hot air gas pipelines for ventilation, environmental protection projects in 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.

Features of Electric Ventilation Butterfly Valve:
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, not affected by the media flow

Electric ventilation butterfly valve is a kind of non-sealed butterfly valve. It is widely used in pipelines with medium temperature ≤300°C nominal pressure 0.1Mpa for building materials, metallurgy, mining, electricity and other production processes to connect, open and close or adjust the amount of medium.

The electric ventilation butterfly valve 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, generally suitable for industrial, metallurgical, environmental protection and other pipelines for ventilation regulation media flow use. Its main features are:
The design is novel, reasonable, unique structure, light weight, rapid opening and closing.
small operating torque, easy operation, effort, and dexterity.
The 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, small size.
The use of aluminum alloy cylinder material, light weight, beautiful appearance.
Manual operation mechanism can be installed at the top and bottom.
Rack-type connection can adjust the opening angle, rated flow.
Actuators can provide feedback indications and various accessories for automatic operation.
IS05211 standard connection provides convenience for installation and replacement of products.
The two-point adjusting screw allows the standard product to have an adjustable range of ±4° at 0° and 90°. Ensure synchronization accuracy with the valve.

The electric ventilation butterfly valve is a kind of non-sealed butterfly valve, which is suitable for pipelines with building medium, metallurgy, mining and power production medium temperature ≤300°C nominal pressure of 0.1Mpa, for connecting, opening and closing or adjusting the amount of medium. The electric ventilation butterfly valve is mainly used in the dusty cold air or hot air gas pipelines of ventilation, environmental protection projects in the industries of gold, chemical, building materials, power stations, and glass, etc., and is used as a gas medium to regulate flow or cut off devices. The electric ventilation butterfly valve is designed and manufactured using a new type of structure in which the midline type disc plate is welded to the short structure steel plate.

Features:
1. 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.
2, there is no connecting rod, bolts, etc., reliable, long service life. Can be installed in multiple stations without being affected by the flow of media.
3, the design is new, reasonable, unique structure, light weight, rapid opening and closing.
4, electric ventilation butterfly valve operation torque is small, easy to operate, effort and dexterity.
5, electric ventilation butterfly valve uses adapted materials to meet the low, medium and high temperature of different media and corrosive media.
