The ventilation butterfly valve can be divided into manual and electric transmission, which can be driven by an electric motor or a turbine to drive the actuator to freely rotate the butterfly plate within 90° to open, close or adjust the medium flow.
Ventilation butterfly valve adopts a new structural form in which a mid-line disc plate and a short structural steel plate are welded. The structure has features of compact, light in weight, easy to install, small in flow resistance, large in circulation, avoiding the effects of high temperature expansion and easy to operate.
There are no connecting rods, bolts, etc., and the work is reliable and the service life is long. Can be installed in multiple stations without being affected by media flow.
Ventilation butterfly valve is used in ventilation, environmental protection engineering, dusty cold air or hot air gas pipelines in chemical, building materials, power stations, glass and other industries. This type of valve should generally be installed horizontally in the pipeline.
We focus on wholesale of electric ventilation butterfly valve, manual ventilation butterfly valves, pneumatic ventilated butterfly valve and general ventilation butterfly valve. Welcome to check the four types of Ventilation Butterfly Valve listed below and contact us if you have any questions.
