Brief Introduction
Q644/45F pneumatic three-way flange ball valve can be L-type or T-type. L-type (BQ644F) three-way ball valve is used for switching the flow direction of the medium and can connect two perpendicular channels; T-type (BQ645F) three-way ball valve is used for medium diversion, confluence and flow direction switching. T-type three-way can make three channels interconnected or connect two of them. Pneumatic three-way ball valve generally adopts two-seat structure, and can also adopt four-seat structure according to user requirements. It is widely used in water supply, petrochemical, metallurgy, mining, textile, energy, papermaking, food, steel and other pipeline systems to switch the flow direction of the medium and divert or mix the medium.
