Brief introduction of pneumatic three-way ball valve:

Pneumatic three-way ball valve is used for medium reversing, confluence and diversion in pipelines. It is mainly composed of T-type or L-type three-way ball valves connected with pneumatic actuators. According to different connection methods, it can be divided into flanges and internal threads. Pneumatic three-way. type ball valve is to switch or store the flow direction of two mutually perpendicular channels, and achieve the distribution function, while the T-type ball valve can not only switch the flow direction of the material, but also make the three channels Interconnect or close any one of the channels to play the role of diversion and confluence. According to the needs of T conditions, a valve positioner and other related accessories can be installed on the pneumatic one-pass valve liner to control the operation of the ball valve core. Achieve automatic control of the medium in the pipeline.

Advantages of pneumatic three-way ball valve:

1. Different connection forms can be selected, which are divided into pneumatic flange three-way ball valve and pneumatic thread three-way ball valve to meet different working conditions. 2. Sealing effect, the elastic deformation of soft seal tetrafluoroethylene can achieve leak-free sealing.

3. One valve with multiple functions: it can be made into an L-shaped port or a T-shaped port to achieve functions such as distribution, confluence, and diversion.

4. The pneumatic three-way ball valve is easy to install, and any port can be used as the flow inlet of the medium, and there is no leakage

5. It is widely used in environmental protection, oil products, metallurgy, steam, energy, papermaking, food and other pipeline systems to change the flow direction of the medium or achieve the separation or mixing of the medium.
