Pneumatic flanged butterfly valve is composed of flange butterfly valve and pneumatic actuator. The flanges at both ends of butterfly valve body are connected with pipeline flange, which has the advantages of relatively reliable sealing performance.
Pneumatic flanged butterfly valve can be divided into elastic seal and metal seal according to the sealing form. The elastic seal materials include NBR and fluororubber, the hard seal butterfly valve is multi-layer metal hard seal, which has the advantages of elastic seal and excellent sealing performance at low temperature. Compared with the clip type butterfly valve, the pneumatic flanged butterfly valve has higher pressure resistance. Generally, the flange type butterfly valve is used in the high pressure condition.

Pneumatic flanged butterfly valve is equipped with pneumatic actuator, the speed of pneumatic actuator is relatively fast, and does not need workers to do it by themselves, which saves human resources and time to a great extent·
The main advantages of the pneumatic flanged butterfly valve are simple structure, small volume, light weight and low cost. The pneumatic butterfly valve is especially remarkable. It is installed in the high-altitude underpass and controlled by two position five way solenoid valve. It is easy to operate and can also adjust the medium flow
