Design prioritizing landscape quality in waterfront environments! Lineup of powered flap gates and expansion gates.
This product is a gate without gateposts that considers the landscape, unlike conventional lift gates. We offer a lineup of "power flap gates" that drive the flap using hydraulic cylinders, and "expansion gates" that seal the pipe with an air-inflated rubber bag (rubber gates for pipelines). The expansion gate comes in two types: one designed to be installed in concrete culverts and another that is installed with the entire casing. 【Power Flap Gate Features】 ■ Eliminates the shortcomings of commercially available flap gates ■ Responds to reverse water pressure ■ Does not obstruct water flow ■ Opens and closes using hydraulic cylinders *For more details, please refer to the PDF materials or feel free to contact us.
