Pneumatic 3-way flange 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.
1. Pneumatic 3-way flange ball valve adopts an integrated structure, seal type of four valve seats and less flange connection, ensuring high reliability and light weight.
2. Pneumatic 3-way ball valve spool is divided into T type and L type, with long service life, large flow capacity and small resistance.
3. The ball valve can be divided into single-acting and double-acting type. The single-acting type has the feature that once the power source has fault, the ball valve will be under a state required by the control system.
