Introduction

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 . 

Advantage
 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.




Applications
 centralized heating, coal gas pipe, waste gas treatment system, heat supply system
