Product features

It is mainly composed of three-way ball valve and T-type ball valve, which can be connected with the three-way valve and the pneumatic split valve according to the three-way connection mode. The pneumatic three-way L-type ball valve is used to switch or cut off the medium flow direction of two mutually perpendicular channels, playing a distribution role, while the T-type ball valve can not only switch the medium flow direction, but also make the three channels connected with each other or close any one of them to play the role of shunt and confluence. According to the needs of working conditions, the valve positioner and other related accessories can be installed on the pneumatic three-way ball valve actuator to control the ball core operation of the ball valve and achieve the automatic control of the medium in the pipeline.

Advantages of pneumatic three-way ball valve:
1. It can be divided into pneumatic flange three-way ball valve and pneumatic thread three-way ball valve to meet different service conditions.
2. The sealing effect is excellent. The soft seal and the elastic deformation of tetrafluoroethylene can achieve no leakage seal.
3. It can also be made into one port, L-type and multi-purpose distributing valve.
4. The pneumatic three-way ball valve is easy to install. Any port can be used as the medium inlet, and there is no leakage.
5. It can be widely used to change the flow direction of oil products, metallurgy medium, etc.
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 / ANSI b165.
4. Structural length: jd-2002
Feedback device: also known as limit switch, remote feedback switch signal (explosion-proof)
Solenoid valve: two position five way for double action and two position three-way for single action (explosion-proof)
Triplet: it can stabilize the air source, filter and add lubricating oil to the cylinder
Valve positioner: input 4 ~ 20mA signal to realize valve regulation yt-1000r

Flow direction principle of pneumatic three-way ball valve:
 
The pneumatic three-way ball valve is divided into L-type and T-type according to the structure and flow direction. The medium flow direction diagram is as follows.

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