Understand the ventilation butterfly valve

As a bidirectional opening and closing device for ventilation and dust removal pipeline, ventilation butterfly valve is suitable for ventilation and dust removal and environmental protection systems in metallurgy, mining, cement, chemical industry, power generation and other industries.

The ventilation butterfly valve is made of the same material as the valve body. The applicable temperature depends on the material of the valve body. The nominal pressure is less than or equal to 0.6mpa. Its main characteristics are:

1, novel design, reasonable, unique structure, light weight, fast opening and closing.

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

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