Sealing surface type has a plane and auricle. Flange structure is simple, small size, light weight; close and reliable, the current ball valve sealing surface materials widely used plastic, good sealing, in the vacuum system has also been widely used; easy maintenance, ball valve structure is simple, the seals are generally activities Of the demolition and replacement are more convenient; in full or closed, the ball and the sealing surface of the valve seat and the media isolation.
