Pneumatic butterfly valve can make full use of air pressure
This is because I don't know much about pneumatic butterfly valves. The pneumatic butterfly valve can take away some difficult and dirty media by using the air source pressure. This is conducive to the effectiveness of pneumatic butterfly valves in terms of pipeline safety. Pneumatic butterfly valves have very unique characteristics, but there are still many unpublished projects that have not been applied to pneumatic butterfly valves.
These projects are under study. It will pack the valve stem very tightly, resulting in large hysteresis. Cause mechanical damage and shorten valve life. The current method is to treat the butterfly valve with water. In special cases, such as when the inclination angle is large or the valve itself is too heavy, it may tilt, and the valve shall be protected by supporting parts. Remove dust and welding slag.
After installation, in order to ensure that there are no impurities left in the valve, the valve should be cleaned again, that is, when introducing media, all valves should be opened to prevent impurities from getting stuck. Its system configuration and composition are flexible and adaptable. Therefore, the pneumatic butterfly valve can use shielded twisted pair or low-cost unshielded three wire cable for internal communication of the system.
