Fully welded ball valve
FREE-Valve’sFullyWeldedBallValve are widely used in almost all the industry .Compared to the general casting ball valve,fully welded ball valve have a highly performance and longer life time .It was widely used incity gas ,city heat supply ,oil chemical industry,ship building ,steel ,power plant etc . Fully welded ball valve canbereliable run in the long time ,easy tobeinstalledand less maintenance work .
Benefits
1.Valve body material is the same as the pipe material , so they will not occur transformation due to unbalanced stress.
2.Face to face dimensions can be made according to customer requirement.
3.Material of valve seat is made up ofPTFE+20%Csealing ring andmetal sealing,which can adapt to the change of pressure and temperature,So the leakage will not occur during the pressure and temperatureRange.
4.The ballbodyhasa highly machining precision due to the tracking of computer detector,so the ball valve was shut off/shut on conveniently.
