A Pneumatic Control Butterfly Valve is a type of butterfly valve used to control the flow of air from a source of air, such as a compressor or an air conditioning system. To operate a butterfly valve, the valve must be opened and closed to control the airflow. The butterfly valve is typically operated by a pneumatic control valve mounted on the air source.
The butterfly valve is then opened and closed to control the airflow. When the butterfly valve is opened, the air supply to the air source is increased. As a result, the pressure inside the source of air increases. This pressure increase causes the butterfly valve to open and close to control the airflow. When the butterfly valve closes, the pressure inside the source of air decreases, and so does the flow of air through the source of air.
