first, the pneumatic three-way ball valve
pneumatic three-way ball valve can be divided into l-shaped pneumatic three-way ball valve and t-shaped pneumatic three-way ball valve, l-shaped (q44f) three-way ball valve for medium flow switching, channel connection; t-shaped (q45f) three-way ball valve for medium diversion, confluence and flow switching. t-tee can make the three channels connected to each other or the two of the channels. three-way ball valve generally use two seat structure, can also be used according to user requirements four seat structure.
