Always open flap gate "U Gate"

Always open flap gate "U Gate"

A hinged floating gate that completely resolves the problem of clogging!

The "U Gate" is a permanently open flap gate designed to overcome the shortcomings of conventional non-powered automatic gates, such as clogging, and to ensure safe and reliable closure during floods. With a simple structure, the gate hangs in an inverted L shape, pivoting around a hinge located at the tip that extends from the riverbank during normal water levels. 【Features】 - No operation or power required, which avoids operational errors and saves maintenance costs. - Remains open during normal water levels, allowing the movement of fish and crustaceans without obstruction. - Can be manufactured at a slightly lower cost than floating structure gates or flap gates. - The gate body is made of aluminum, and other components are made of stainless steel, eliminating concerns about corrosion. *For more details, please download the PDF or feel free to contact us.*

Flap Gate "Auto Gate Junior"

Flap Gate "Auto Gate Junior"

Eliminating the drawbacks of conventional flap gates! Introducing a backflow prevention gate for small drainage pipes.

The "Auto Gate Junior" is a flap gate of the "balance weight" type that was born from the new technology of the "Auto Gate" developed by our company. Under normal conditions, the gate opens due to the action of the balance weight and smoothly drains water. Additionally, during floods, it quickly closes due to the interaction between the balance weight and the float. 【Features】 <Bearings> ■ It uses submerged, maintenance-free bearings on the rotating shaft to reduce friction resistance, allowing the gate to open and close smoothly. <Gate Opening> ■ The gate is in a 10° open position under normal conditions, which does not hinder the flow of water. ■ There is no need to lift the gate under normal conditions. *For more details, please refer to the PDF document or feel free to contact us.
