Manufacturer and Exporter of PTFE / FEP / PFA / PVDF Lined Check Valves For Corrosive Application

ICON supplies lined wafer check valve and lined ball check valve.

Check valves are Non-Return Valves. It allows flow of liquid in one direction only.

ICON offers PTFE / FEP / PFA / PVDF lined check valves. These lined valves are used for highly corrosive chemicals where higher alloy materials are costlier than lined ones, thus protecting the expensive equipment, extending the life of it and assuring superior performance.

The material selection for fluorocarbons lining of valves will depend on working conditions like chemical and mechanical characteristics of the fluid flowing inside the pipe, valves, temperature, etc.

Unique Features of Lined Check Valve- Lined Ball Check Valve and Lined Wafer Check Valve

  • The Ball Check valve is suggested for use in low-pressure drop application.
  • The lined Wafer Check valve is suggested for compact construction & low in cost and available in the widest range of sizes.
  • Lining offered PTFE / FEP / PFA / PVDF. The thickness of the lining is between 3.5 to 6 mm.
  • The lining resins from renowned manufacturers like DuPont, Daikin, GFC.
