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.
