First, the pneumatic butterfly valve Introduction
Pneumatic butterfly valve and valve body made of the same material into a ring, the use of electric or pneumatic drive. The applicable temperature with the body material selection may be, nominal pressure ≤ 0.6MPa, generally applicable to industrial, metallurgical, environmental protection and other pipe for ventilation regulation of media flow purposes.

 Second, the main features of pneumatic butterfly valve
 1, a new design, reasonable, unique structure, light weight, quick opening and closing. 
 2, torque is small, easy to operate, labor-saving smart. 
 3, the use of adaptive materials to meet the low, medium and high temperature of different media and corrosive media.

 Third, the pneumatic butterfly valve Dimensions (PN0.5,2.5)
