The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve is a pneumatic valve that uses a circular butterfly plate that rotates with the valve stem to realize the opening and closing. Increasing use on medium-bore pipes
The main advantages of the pneumatic butterfly valve are simple structure, small size, light weight, and low cost. This characteristic of the pneumatic butterfly valve is particularly remarkable. It is installed in the high-altitude dark passage, and it is easy to operate through the control of the two-position five-way solenoid valve, and the flow medium can also be adjusted.
