Pneumatic butterfly valve is small for the transfer medium in the pipe, which is because the effective flow area of the large diameter of the pneumatic butterfly valve in the valve is larger than that of the general butterfly valve.
In addition, the speed of the pneumatic butterfly valve is faster when opening and closing is faster, because its valve stem can complete the full-opening actions as long as the right angle is moved.
The sealing surface of the pneumatic butterfly valve uses high-grade rubber materials, which makes the sealing surface also have good sealing in the working environment of low pressure, and its sealing surface is similar to the metal butterfly valve.
