The pneumatic ball valve is compact in structure, reliable in sealing, simple in structure, and easy to maintain. The sealing surface and spherical surface are always closed, not easily eroded by media, and easy to operate and maintain. It is suitable for general working media such as water, solvent, acid, natural gas, etc. It is mainly used to cut off or connect the media in the pipeline, and can also be used for fluid regulation and control.

Color of stainless steel pneumatic butterfly valve
I'm afraid the stainless steel products that everyone first came into contact with were stainless steel tableware. We all know that their color is bright. Some flat stainless steel can even be used as mirrors.
Are all stainless steel products bright in color? Neither.
Some customers think that the color of stainless steel pneumatic butterfly valve should be relatively bright. In fact, we will find that some types of stainless steel pneumatic butterfly valves are snow white or even dark silver gray. For example, 316L stainless steel corrugated pipe is not bright in snow white color.
I once thought that the bright color of 304 stainless steel pneumatic butterfly valve is the way to distinguish 304 from 201 pneumatic butterfly valve made of ordinary material. Later, I learned that some 201 pneumatic butterfly valves have bright colors, while some 304 pneumatic butterfly valves have dark colors. In fact, the bright color of stainless steel pneumatic butterfly valves is mainly due to the use of electroplating or polishing, while some 304 stainless steel pneumatic butterfly valves will reduce their luster due to manufacturing processes, such as pickling, but the acid and alkali resistance will not be affected.
