Features

D971F Lining butterfly valve

1, Both cavity and disc are lined F46 or PFA, which can be proof of almost all the corrosive medium and long time of permeating chloridion.

2, The soft seat will be deformed properly to ensure zero leakage when the valve is closed.

3, The substrate of soft material lined seat ring is formed by rubber injection.

4, The disc and stem are made as a while,the PFA bearing is used not only for guiding but also for good lubrication.
