Pneumatic 3-way thread ball valve
Pneumatic 3-way ball valve can be divided into L type and T type. L type 3-way ball valve is used for switching the flow direction of media and making two orthogonal passages connected. Four-seat 3-way ball valve has features including artistic appearance and compact and reasonable structure. It can not only switch the flow direction of media, but also connect three passages, or close one passage while making the other two passages connected. Thus, it can control the convergence and diversion of the media in pipe flexibly.
