Product Description

Product  Description 

Pneumatic flange butterfly valve, equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast and does not require manual labor, which greatly saves human resources and time. The main advantages of pneumatic flange butterfly valve are simple structure, small size, light weight, low cost, and this feature is particularly significant. 

A pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem for opening and closing, to achieve activation action. It is mainly used as a block valve, and can also be designed to have the function of adjustment or both.

Butterfly valves are increasingly used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valves: stainless steel pneumatic butterfly valves, hard sealed pneumatic butterfly valves, soft sealed pneumatic butterfly valves, and carbon steel pneumatic butterfly valves. 

The main advantages of pneumatic butterfly valves are simple structure, small size, light weight, and low cost. This feature is particularly significant for pneumatic butterfly valves, which are installed in high-altitude tunnels and controlled by a two position five way solenoid valve for easy operation. They can also adjust the flow medium.

Detailed  Photos 

Ventilation butterfly valves are used in ventilation and environmental protection engineering in industries such as chemical, building materials, power plants, glass, etc., as pipeline control devices for regulating flow or cutting off gas medium in dusty cold or hot air pipelines. This type of valve should generally be installed horizontally in pipelines.
