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.
