FREE-VALVEsFull boreWeldedBallValve 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 tobeinstalled and 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 with*0%C sealing 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 ballbodyhas a highly machining precision due to the tracking of computer detector,so the ball valve was shut off/shut on conveniently.
