Advantages
The working principle of three piece flange ball valve is to make the valve unblocked or blocked by rotating the valve. The ball valve has the advantages of light switch, small volume, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed and are not easy to be eroded by the medium. It has been widely used in various industries.
