Ventilation butterfly valve: a key dust removal accessory
Aug 04,2025
The ventilation butterfly valve is the core control component of the dust removal system, which adjusts the airflow by rotating the valve plate to ensure stable operation of the system and adapt to the dust removal needs of multiple industries worldwide.
Types and adaptation scenarios
1. Manual type: With a simple structure, it is suitable for small systems or scenarios with low adjustment frequency, and has low cost.
2. Electric type: remote control, can be linked with automation systems, suitable for large precision dust removal equipment.
3. Pneumatic type: Fast response, resistant to high and low temperatures, dust, suitable for flammable and explosive environments.
The valve body material is selected according to the medium: cast iron/carbon steel is used for ordinary working conditions, stainless steel is selected for corrosive dust, and high-temperature resistant alloys are used for high-temperature scenarios.
central role
1. Adjust the airflow of each branch to prevent pipeline wear or dust deposition.
2. Stabilize the system pressure to ensure efficient filtration of the filter bag.
3. Urgently cut off the airflow to prevent the leakage of unpurified gas.
4. Implement partition control to reduce energy consumption and maintenance costs.
Selection and maintenance
The selection should match the characteristics of the medium (temperature, corrosiveness), pressure rating, and local standards (such as EU DIN, North American ANSI flanges).
Maintenance points: Regularly clean dust to prevent jamming, check the aging of seals, and lubricate the drive device as needed.
As the "flow manager" of the dust removal system, the adaptability of the ventilation butterfly valve directly affects the dust removal efficiency and is a key component of foreign trade dust removal projects.
