Fully Welded Ball Valve

Q61F fullly welded ball valve, there will be no external leakage. Processing of the ball valve has advanced computer detector tracking test, so the ball machining precision is high.

As the valve material is same as pipe material, there will be no stress uneven nor deformation when earthquake or vibration caused by the vehicle passing through. Ball valve seal ring adopts RPTFE with 25% carbon, to ensure complete no leakage.

Full weld ball valve can be buried directly underground, full weld ball valve do not need to build large valve wells, simply set up small shallow wells on the ground, greatly saving construction costs and engineering time. According to the pipeline construction and design requirements, ball valve body length and stem height can be adjusted.
