Ventilation butterfly valve 通风蝶阀
High quality ventilation butterfly valve for dust removal pipeline. Manual, electric, pneumatic types available, carbon steel/stainless steel material, good sealing, high temperature resistance, used for airflow regulation in power, metallurgy, foundry dedusting systems.
- Product introduction
Ventilation butterfly valve is core gas regulating and cut-off accessory for industrial dust removal and ventilation pipelines. It controls airflow volume, pipeline opening and closing by 90° rotating the disc via manual, electric or pneumatic driving device, featuring small flow resistance and good airtightness. It is matched with dust collector, exhaust pipe, silo and conveying equipment, applied for dusty flue gas, hot air ventilation cut-off and flow regulation in power plant, metallurgy, chemical, building materials, foundry and environmental protection industries.
Product Classification:
1.Manual ventilation butterfly valve: handle/worm gear drive, low cost, easy operation for conventional ventilation pipelines
2.Electric ventilation butterfly valve: electric actuator drive, remote automatic control, compatible with PLC linkage system
3.Pneumatic ventilation butterfly valve: cylinder drive, fast switch, suitable for automated dust removal production lines
4.Flanged/welded ventilation butterfly valve: two connection types to fit different pipeline installation conditions
Product Advantages:
1.Compact structure, lightweight, easy on-site installation and pipeline matching
2.Low air leakage rate, reliable sealing, stable air pressure of dust removal ventilation system
3.Integral forged valve shaft, anti-deformation, anti-wear disc, long service life for dusty flue gas
4.Multiple material customization, high temperature and corrosion resistant optional
5.0-90° stepless adjustment, accurate airflow control, low operation failure rate
