1) Corrosion resistance.Because the parts of the contact medium are
lined with fluorine plastic (lined with F46 or PFA), the acid and
alkali resistance is strong.
2) No leakage.With the valve core (ball of the ball valve,
butterfly plate), the seat is lined with fluorine plastic (F46 or
PFA), which is a soft seal to ensure no leakage.
3) Good seal performance.Control valve, shutoff valve, stop valve
1.6 Mpa under the four-fluorine bellows seal, sealing performance
4) Small flow resistance and large circulation ability.
5)If the valve locator is used, the proportional adjustment is
6) The valve can be equipped with various types of electric
actuators and form the zdwf-16 electric plastic butterfly valve
