Ball Series: Details Q644F / Q645F pneumatic ball valve: the pneumatic ball valve Overview: pneumatic ball valve can be divided into L-shaped and T-shaped, L-shaped (Q44F) ball valve is used to switch the flow of media, make mutually perpendicular two-channel connection; T-shaped (Q45F) ball valve for media streaming, confluence and flow switch. T-ball valve allows three interconnected channels or to two of passage. Generally use two-way ball valve seat structure, we can use four-seat structure according to user requirements.
