The Plasti-Fab flexible neoprene flap gate is the answer for applications requiring corrosion resistant equipment suitable for sea water and most low pH water. Simple construction and light weight make installation and maintenance easy. The flap gate’s molded body of reinforced copolymer has a 125 lb. pattern flange and a molded neoprene flap which also acts as a hinge. The flexible flap with molded-in weight reduces the possibility of pounding which is often a problem on valves having metal to metal seats. Body flanges can be drilled to accept standard bolt sizes when connecting to pipe flanges or can be drilled for smaller bolts when they are to be fastened directly to wall surfaces. We have three different kinds of flap gates. Our Rigid Round Flap Gates run in sizes from 4″ to 96″, rectangular flap gates range from 12″ to 96″ and our flexible rectangular flap gates range from 36″ to 96″.
