Benefits:
- Valve body material is the same as the pipe material , so they will not occur transformation due to unbalanced stress .
- The factory can make Face to face dimensions according to customer requirement.
- 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.
- The ball body has a highly machining precision due to the tracking of computer detector,so the ball valve is going to shut off/shut on conveniently.
Application industry:
centralized heating, coal gas pipe, waste gas treatment system, heat supply system
