Carbon Steeel Handle Fully Welded Ball Valve, Brand Name : FREE-VALVE

Handle fully welded ball valve free-valve's handle 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 offshut on conveniently.
