Drain water back flow  preventer fiberlgass frp flap gate 

 Introduction:

FRP check-stop valve is mainly made of non-saturated polyester resin as a base, making to sheet and then molding into production. According to material , there are cast iron check-stop valve, steel check-stop valve, FRP check- stop valve. According to shape, there are square,round, pontoon flat,flat flap check-stop valve.FRP check-stop valve installed at the end of the drain pipe , prevent the external water flowing back. It is composed of a valve seat , a sealing ring and a hinge.

Advantage:

Saving labor (won’t need manual operation);

Long service life ( 30-50years, simple mechanical structure, easy maintenance);

Corrosion resistance (acid and alkali resistance, not easy to cottode);

Light weight (it is the 1/4 of cast iron check-stop valve);

Strong strength , good dimensional stability;

Specification:DN300-1000mm 

                          Joint Type:PN10 flange
