National standard pneumatic butterfly valve products
The closing member is a disc shaped butterfly plate. A valve that opens, closes, and regulates fluid around a fixed shaft is called a pneumatic butterfly valve. Pneumatic butterfly valve is a rapidly developing valve product in the near future. It has the characteristics of simple structure, small volume, light weight, less material consumption, small installation size, rapid switching, 90 degree reciprocating rotation, small driving torque, etc.
Since the valve plate movement of the pneumatic butterfly valve is being wiped, most pneumatic butterfly valves can be used for media with suspended solids. According to the strength of the seal, it can also be used for powder and granular media. Note that there are multiple levels. The metal hard seal pneumatic butterfly valve is not suitable for this working condition, because once the particles enter the non-metallic interlayer, the sealing performance will be affected, or even the sealing surface will be damaged.
