Fully welded ball valve
Free-valve's fully welded ball valve 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 in city gas , city heat supply , oil chemical industry, ship building , steel , power plant etc . Fully welded ball valve can be reliable run in the long time , easy to be installed 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 of ptfe+20%c sealing ring and metal sealing , which can adapt to the change of pressure and temperature, so the leakage will not occur during the pressure and temperature range.
4.The ball body has a highly machining precision due to the tracking of computer detector, so the ball valve was shut off/shut on conveniently.
