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. It is used more and more on medium-bore pipes.

 butterfly plate outer circle using spherical shape, improve the sealing performance and prolong the service life of the valve, with pressure open and close more than 50,000 times still maintain zero leakage. the sealing parts can be replaced, and the sealing is reliable to achieve two-way sealing
