Product features

Pneumatic three-way ball valve is used for reversing, converging and diverting the medium in the pipeline. It is mainly composed of T-type or L-type three-way ball valve and pneumatic actuator. It can be divided into flange and internal thread according to different connection methods. The pneumatic three-way L-type ball valve is used to switch or cut off the flow direction of the media in two mutually perpendicular channels, playing a distribution role. The T-type ball valve can not only switch the flow direction of the media, but also make the three channels connect with each other or close any one of the channels, playing the role of diversion and convergence. The pneumatic three-way ball valve actuator can be equipped with valve positioner and other relevant accessories according to the working conditions, which can control the operation of the ball valve core and achieve automatic control of the medium in the pipeline.

Advantages of pneumatic three-way ball valve:
1. Different connection forms can be selected, including pneumatic flange three-way ball valve and pneumatic threaded three-way ball valve, to meet different operating conditions.
2. The sealing effect is excellent, and the flexible deformation of soft sealing tetrafluoroethylene can achieve leak free sealing.
3. One valve for multiple purposes: it can be made into L-shaped port or T-shaped port to achieve the functions of 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 without leakage.
5. It is widely used in environmental protection, oil products, metallurgy, steam, energy, paper making, food and other pipeline systems to change the flow direction of media or to achieve the separation or mixing of media.
Standard specification for pneumatic three-way ball valve:
 
1. Design and manufacture: GB ／ T12237-1989; APl608。
2. Inspection and test: GB ／ T13927-1992; APl598。
3. Flange connection: JB ／ T79] - 2-1994; ASME／ANSIB165。
4. Structure length: JD-2002
Echo: also called limit switch, remote feedback switch signal (explosion-proof)
Solenoid valve: double acting two position five way, single acting two position three way (explosion-proof)
Triple part: it can stabilize the air supply, filter, and add lubricating oil to the cylinder
Valve positioner: input 4~20mA signal to realize valve regulation function YT-1000R

Description of flow direction principle of pneumatic three-way ball valve:
 
The pneumatic three-way ball valve can be divided into L type and T type according to the structure and flow direction. The flow direction of the medium is shown below.

The L-type three-way ball valve can only connect or cut off two mutually perpendicular and orthogonal pipelines, and can not keep the third pipeline connected at the same time. It only plays the role of distribution.
T-type three-way ball valve can make three orthogonal pipes connect with each other or cut off any third channel to achieve the function of two in and one out or one in and two out, playing the role of diversion and confluence.
