Design features and application standards of pneumatic three way ball valve

Pneumatic three way ball valve can be divided into L pneumatic three way ball valve and T pneumatic three way ball valve. L pneumatic three way ball valve for medium flow direction switching, can make each other vertical two channels connected. Three way ball valve generally adopts two seat structure, also can be used according to user requirements four seat structure. Four three seat sealing valve has beautiful appearance, compact and reasonable structure, which not only enables media flow switch, also can make the three channels connected with each other, but also to turn off any channel, connected to the other two channels, control of media in the pipeline or shunt flexible confluence.
