What is PTFE Lined Valve?

A PTFE lined valve is an internally coated industrial valve with Polytetrafluoroethylene (PTFE), a corrosion-resistant fluoropolymer. The lining protects the valve from corrosive chemicals, acids, and elevated temperatures, giving it durability and safe fluid handling in hostile environments. Commonly applied in chemical, pharmaceutical and petrochemical processes, PTFE lined valves exhibit good non-stick properties, low friction, and longevity. They are most appropriate for handling corrosive or poisonous fluids in which metal valves would corrode or be useless.
