Classification of pneumatic butterfly valves: stainless steel pneumatic butterfly valves, hard seal pneumatic butterfly valves, soft seal pneumatic ball valves, carbon steel pneumatic butterfly valves. The main advantages of pneumatic butterfly valves are simple structure, small volume, and light weight. They can be installed in high-altitude tunnels and controlled by two five way solenoid valves for easy operation. They can also regulate the flow medium. Simply rotate 90 ° to quickly open and close, with simple operation. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance for the medium to flow through the valve body. Therefore, this type of valve generates a small pressure drop and has good flow control characteristics. Under low pressure, good sealing can be achieved.
It can be widely used in the working environment with hygienic requirements, for conveying powder, particles, gel, liquid, etc. It is mainly used in the pharmaceutical, food, cosmetics, and fine chemical industries.
