DN50-300 Pneumatic butterfly valve 

Product Introduction of Pneumatic butterfly valve A pneumatic butterfly valve is a type of industrial valve used to control the flow of fluids in pipelines or other systems. It is operated by a pneumatic actuator, which uses compressed air to open and close the valve. The valve features a disc or plate, which is mounted on a shaft in the center of the valve body. When the valve is open, the disc is turned parallel to the flow of fluid to allow fluid to pass through the valve. When the valve is closed, the disc is turned perpendicular to the flow of fluid to block the flow. The pneumatic actuator used to operate the valve is typically a cylinder or piston, which is connected to the valve disc through a shaft or other mechanism. The actuator can be controlled by a variety of devices, including sensors, switches, and controllers. Pneumatic butterfly valves are commonly used in industries such as chemical processing, food and beverage production, water treatment…
