Q644(5)F pneumatic flange three-way ball valve is divided into L-type pneumatic internal thread ball valve and T-type pneumatic internal thread ball valve.Q644(5)F pneumatic flange three-way ball valve is divided into L-type pneumatic internal thread ball valve and T-type pneumatic internal thread ball valve. The L-type is suitable for the conversion of medium flow direction, enabling the connection of two perpendicular channels. The L-type is suitable for the conversion of medium flow direction, enabling the connection of two perpendicular channels. The T-type is suitable for the diversion, confluence or flow direction switching of the medium. The double-layer valve stem packing meets the German leakage test requirements. The T-type is suitable for the diversion, confluence or flow direction switching of the medium. The double-layer valve stem packing meets the German leakage test requirements. After the system depressurizes, the entire valve body does not need to be removed for inspection and maintenance. After the system depressurization, the entire valve body does not need to be removed for inspection and maintenance. The pneumatic three-way internal thread ball valve can be used as an inlet for any of its ports without leakage, and can be made into L-type or T-type channels according to the working conditions. 

 The pneumatic three-way internal thread ball valve can be used as an inlet for any of its ports without leakage, and can be made into L-type or T-type channels according to the working conditions. 

The pneumatic three-way ball valve has two types of sealing structures (two-seater and four-seater), and the valve core channels have two structural forms (L-shaped and T-shaped).The pneumatic three-way ball valve has two types of sealing structures (two-seater and four-seater), and the valve core channels have two structural forms (L-shaped and T-shaped). By controlling the rotation angle of the valve core, the connection state between the valve core channel and the pipe opening can be changed, enabling different combinations of control for three branch pipes. By controlling the rotation angle of the valve core, the connection state between the valve core channel and the pipe opening can be changed, enabling different combinations of control for three branch pipes. It has a large flow capacity and can control gases, liquids, and steam. It has a large flow capacity and can control gases, liquids, and steam. It is more suitable for controlling high-viscosity and fibrous particle-like fluids. It is more suitable for controlling high-viscosity and fibrous particle-like fluids. It is also applicable in situations with strict sealing requirements. 

 It is also applicable in situations with strict sealing requirements. 

The two-valve-seat sealed three-way ball valve features a compact structure, an attractive appearance, and excellent sealing performance. It can switch the flow direction of the medium in the pipeline.The two-valve-seat sealed three-way ball valve features a compact structure, an attractive appearance, and excellent sealing performance. It can also connect or close the two perpendicular channels. It can switch the flow direction of the medium in the pipeline. It can also connect or close the two perpendicular channels. The four-valve-seat sealed three-way ball valve has a beautiful appearance and a compact and reasonable structure. The four-valve-seat sealed three-way ball valve has an elegant appearance and a well-designed compact structure. It not only enables the switching of the medium flow direction, but also allows the three channels to be interconnected. It not only can switch the flow direction of the medium, but also can connect the three channels, and at the same time, it can close any one channel, allowing the other two channels to be connected, providing flexible control over the merging or diversion of the pipeline medium. At the same time, any one of the channels can be closed, allowing the other two channels to be connected, providing flexible control over the merging or diversion of the pipeline medium.
