Product Description
PTFE /PFA Lined Wafer Type Single Door Check Valve ( H74F)
PTFE /PFA Lined Wafer Type Single Door Check Valve ( H74F) APPLICATION
PTFE/PFA Lined ball valve is epecially designed for controlling the usual corrosive medium. Its body inner surface is lined with fluorine plastic like FEP/PTFE/PTFE or some other kinds of rubber. It features a high strength and aprominent performance of corrosion resistance. It can be selected to suit with different working temperature and fluid pipelines.

PTFE /PFA Lined Wafer Type Single Door Check Valve ( H74F)
Lined Wafer Type Single Door Check Valve only allow one way flow direction and prevent the back-flow of liquids in pipeline. Generally check valve is automatically working, under the pressure function of one direction flow, the disc open, while when the liquid back flows, the valve will cut flow. PTFE Lined Disc Can also guarantee the tight sealing performance.

Working Principle
Generally check valve is automatically working, under the pressure function of one direction flow, the disc open, while when the liquid back flows, the valve will cut flow. PTFE/PFA Lined check valves only allow one way flow direction and prevent the back-flow of liquids in pipeline. The solid PTFE ball at valve body lining guarantees that ball rolls into the seat due to gravitation.
