The pneumatic electric wafer butterfly valve cannot be opened? (3) Inspection after installation
① Operate the driver to open and close the pneumatic ball valve for several times, which should be flexible without stagnation, to verify that it works normally.
② The design of connecting pipeline requires that the sealing performance of the flange joint surface between the pipeline and the spherical cavity should be checked
Elastic sphere
The ball of the pneumatic ball valve is elastic. The ball and valve seat seal ring are made of metal materials, and the sealing pressure is very high. The pressure of the medium itself cannot meet the sealing requirements, so external force must be applied. This valve is suitable for high temperature and high pressure media.
