General [Q61N-320] type valve main JB / t2203-1999 "length" of the main valve structure. At present, most of the ball valve manufacturers in China are designed and produced according to this standard. Through textual research, the connection sizes of different manufacturers are not uniform. In order to have a unified standard, users can exchange the same specifications when selecting and installing, and double high valves suggest that design institutes and users should be selected according to standard, and the ball valve manufacturers should be designed and manufactured according to standards.
