ANSI Standard PTFE Lined Plug Valve

FVF ANSI Standard PTFE Lined Plug Valve

  • FVF lined plug valve is a valve that uses a plug body with a through hole as the opening and closing part and the plug rotates with the valve stem to realize the opening and closing action.
  • FVF plug valve can be opened and closed quickly with small fluid resistance. Since the movement between the sealing surfaces of the plug valve has the function of wiping and can completely prevent the contact with the flowing medium when it is fully opened, so it can also be used for the medium with suspended particles.
  • The plug and lined valve body have an ideal conical design.The top seal forms the second external seal to prevent the medium from leaking out of the valve stem when the sealing surface fails.
  • By removing the four bolts on the bonnet, all components in the valve can be taken out.Then the valve parts can be directly replaced without removing the valve from the pipeline.
  • Plug valves are mainly used to cut off the flow of medium and can also be used for medium distribution (three-way plug valve).
  • FVF lined plug valve is applicable to any corrosive medium except "molten alkali metal and elemental fluorine".It is widely used in chemical industry, petroleum, medicine, food, steel smelting, paper making, water and electricity, environmental assurance etc.
