ZSH Shanghai Valve Manufzcturing Co.,LTD.

Three way ball valve has T type and L type. T type can make the three orthogonal channels and cut off the third channels Unicom, from the diversion, the confluence of the role. Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.
Features: one or two valve seat sealing three ball valve with compact structure, beautiful appearance, good sealing performance. Can also realize the switching of the pipeline intermediary flow. Can also make the resistance of the two channels perpendicular to the connection or close. Two, the four seat sealing ball valve three beautiful shape, 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 to another channel connectivity, 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.
