Lined wafer butterfly valve is split body designed for a wide variety of liners such as PTFE, EPDM, NBR, FPM, PU to fit a wide range of applications.

PTFE is the preferred material for corrosive applications in chemical industry.
PU is the preferred material for abrasive applications.
EPDM is the preferred rubber for water industries.
NBR is the preferred rubber for oil transportation.
FPM is the preferred rubber for wide range of medium composition and temperature.
Wafer design makes the valve convenient for connection between flanges and save length in pipe line.
