Ventilation Butterfly Valve is an essential industrial control valve specially designed for ventilation,air volume regulation,flue gas isolation and duct cut-off.It is widely installed in dust removal pipelines,HVAC systems,factory ventilation,boiler flue gas exhaust,metallurgy,chemical and environmental protection engineering.

The valve adopts a simple wafer or flange type structure,featuring light weight,compact size,easy installation and low resistance to airflow.The butterfly disc rotates 0–90 degrees to realize stepless adjustment or full on-off of air volume,which can stably control wind pressure and flow in the pipeline.

It is available in carbon steel,stainless steel and high-temperature resistant plate materials.Supporting driving modes include manual,electric and pneumatic.The sealing performance is reliable with low air leakage,suitable for conveying dry air,flue gas,dusty gas and non-corrosive medium.With sturdy structure,stable operation and almost no maintenance,it is the ideal matching accessory for dust collectors,ventilation ducts and industrial exhaust systems.
