Description Material Performance Product Size Specifications

Pneumatic three ball valve is a kind of valve can be divided into L type and T type. L type three way ball valve for medium flow switching, can make each other perpendicular to the two channels (such as the flow chart L). Three way ball valve is generally used two valve seat structure, can also be based on user requirements of four valve seat structure. Four three seat sealing valve has beautiful appearance, compact and reasonable structure, which not only enables media flow switch, also can make the three channels connected with each other, but also to turn off any channel, connected to the other two channels, control of media in the pipeline or shunt flexible confluence.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
