Maintenance method of pneumatic flange butterfly valve

Pneumatic flange hard seal butterfly valve Pneumatic flange hard seal butterfly valve is usually used to control pipeline system software and disconnect material or throttle valve. Usually, it is mainly used for large pipelines. Because the total number of internal parts is small and the structure is relatively simple, it is light compared with ordinary butterfly valves and can control the total flow well.
It is different from the telescopic hard seal butterfly valve in connection mode, which is usually connected by pneumatic flange. In specific applications, the specifications and dimensions of butterfly valves are selected according to the requirements of the natural environment. In addition, before purchase, it is necessary to check the working pressure, pulsation and other factors of the double pressure sealing butterfly valve to prevent damage during transportation. Finally, in the daily maintenance, we should also pay attention to the lubrication of the external thread of the transmission system.
